Free AAMVA Driver's License Barcode Generator

Host your PDF anywhere, Google Drive (use the "anyone with link" share URL), Dropbox, your own server, S3, etc. Paste the public link here. We encode the URL so the QR works forever and never depends on us. Tip: for Google Drive, replace /view in the share URL with /preview for a cleaner mobile view.

Any downloadable file, installer (.exe / .dmg / .deb / .apk), archive (.zip / .tar.gz), document, dataset. Host it anywhere; we encode the URL. The user's browser handles the download per its own MIME-type rules.

JPEG, PNG, WebP, GIF, or HEIC, host it anywhere. Mobile browsers open the image full-screen; desktop browsers show it inline. Common pattern: print on flyers / business cards / packaging so a scan opens a product photo or gallery.

YouTube and Vimeo URLs open natively in their apps on phones. Direct .mp4 / .webm files open inline in any modern browser. Host self-encoded video on your own server, S3, or Cloudflare R2 and paste the URL.

MP3 / OGG / WAV / FLAC / M4A direct URLs play inline in mobile browsers. Spotify (open.spotify.com/track/…) and SoundCloud (soundcloud.com/…) URLs open in their apps. Apple Music / Bandcamp / Tidal links also work.

This menu is too big to encode, point at a hosted menu URL instead. See /menu-qr-code/ for the recommended approach.

Build the menu inline, every item lives inside the QR code itself. Best for food trucks, pop-ups, and single-product cafes. Larger menus should point at a hosted URL instead.

Paste your form's share link, either the short forms.gle/… or the long docs.google.com/forms/d/e/…/viewform form. We auto-prefer forms.gle when both are available since the shorter URL produces a denser QR. Works for surveys, registrations, RSVPs, lead capture, classroom polls.

Local uploads stay in your browser and only appear on the printed card. The QR data uses the URL above.

Entered in your local timezone. Saved as UTC so anyone who scans the QR sees the right wall-clock time in their own timezone.

Scanning opens the attendee's contact card. Event name and session are recorded in the NOTE field so the attendee remembers where they met.

Tip: right-click any spot on Google Maps and copy the coordinates

Use this if you're sharing a receiving address to accept a payment (BIP-21 bitcoin: URI, Ethereum EIP-681, and equivalents). Do not paste a private key, seed phrase, or extended private key (xprv), those control the wallet, not a single payment. Double-check the receiving address in the generated QR matches what you pasted; chain-agnostic address-swap attacks exist.

A red Swiss flag is automatically overlaid on the QR, required by Swiss banks.

Paste a BOLT11 invoice (lnbc...) or a Lightning address. We prefix with the lightning: URI scheme so any Lightning wallet can scan it.

Use this if you're enrolling a new 2FA account in an authenticator app (Google Authenticator, Authy, 1Password, Bitwarden). Do not screenshot, email, or photograph this QR, the secret inside it is a permanent key to the account.

Compatible with Google Authenticator, Authy, 1Password, Bitwarden, and any standard TOTP app.

Use this if you're provisioning a counter-based hardware token (YubiKey OTP) or a system without a reliable clock. Do not use when TOTP will do, HOTP counters drift, and recovery is harder after a dropped sync.

HOTP (RFC 4226) is the counter-based sibling of TOTP. Use it for hardware tokens like YubiKey OTP or for systems without reliable clocks. Same otpauth:// scheme; counter increments per code instead of advancing on time.

Use this if you're a carrier or MVNO issuing an eSIM activation profile to a customer (iOS 17.4+ / Android 13+). Do not share this QR after it's been scanned, the SM-DP+ activation is usually single-use and the profile belongs to one device.

GSMA SGP.22 activation code per the LPA spec. iOS 17.4+ and Android 13+ scan these directly to provision eSIM profiles. Carriers issue the SM-DP+ address and matching ID; the confirmation code is optional second-factor.

Per RFC 3261, opens a SIP softphone (Linphone, Zoiper, Bria, etc.) and dials the address. sips: forces TLS for signalling. Works with Asterisk, FreeSWITCH, 3CX, and any standards-compliant PBX.

Opens the system MMS composer to send a multimedia message (text + image/audio/video attachment). Distinct from sms: in that the recipient receives an MMS-formatted message. iOS, Android and most carrier apps honour this scheme.

Paste the QR URL from your Alipay Receive Money page (Settings → My QR Code → Save). We pass it through verbatim. The Alipay app, AliPayHK, and any device with the Alipay+ scanner will recognise the URL or QR.

Personal receive codes start with wxp://f2f. Merchant codes are https://payapp.weixin.qq.com/... URLs from the Weixin Pay merchant portal. Paste either; we encode verbatim. The WeChat app and any Weixin-Pay-enabled scanner will resolve it.

Swish is Sweden's national P2P / merchant mobile-payment service. Payee can be a private mobile number (Swish-number) or a 1234-style merchant alias. The Swish app on iOS and Android scans the standard swish://payment?data=... URI.

Vipps is Norway's dominant mobile-payment app (now Vipps MobilePay across the Nordics). Send to phone emits a vipps://send?... deeplink for P2P; Merchant short-link wraps a https://qr.vipps.no/... URL.

Paste the link from your Mercado Pago Cobrar page (the https://mpago.la/..., https://link.mercadopago.com.br/..., or full mercadopago.com short-link). Works across MP apps in Argentina, Brazil, Mexico, Chile, Colombia, Uruguay and Peru.

Use this if you need pharma / medical / direct-part-marking symbology or you're encoding for industrial imagers. Do not use for consumer-facing signage, Apple iPhone cameras do not decode Data Matrix natively.

Data Matrix is a square 2D matrix barcode (ISO/IEC 16022) used in healthcare, electronics, manufacturing, and direct-part marking. Holds up to ~2,335 alphanumeric characters in a single tag. Note: this is not a QR code, QR-only styling (eyes, dots, gradients, frames, logos) is disabled and the basic monochrome render is used.

Use this if you're generating boarding passes, transit tickets, or electronic-ID payloads for dedicated scanners. Do not use for public marketing print, most phone cameras won't decode Aztec reliably.

Aztec Code (ISO/IEC 24778) is the 2D barcode used by airline boarding passes, train tickets, and electronic ID. Designed to scan well on phone screens and at low contrast. Holds up to ~3,067 alphanumeric characters. Not a QR; QR-only styling is disabled.

Use this if you're printing an IATA-compliant boarding pass (Aztec, QR, or PDF417) for gate scanners at any of the 200+ airlines that implement BCBP / Resolution 792. Do not use this to board a real flight you didn't check in for, the format carries no cryptographic signature; airline gate systems validate against their own DCS, not against the QR itself.

IATA Resolution 792 / BCBP Implementation Guide v7. Encode as Aztec for mobile boarding passes, PDF417 for printed Type-A stock, or QR for modern gates. We build the mandatory M1 header + a single leg; paste the full BCBP in Advanced for multi-leg itineraries.

Use this if you need stacked-linear barcode for driver's-licence parsing, boarding passes, airbills, or AAMVA workflows. Do not use for normal consumer phone-camera signage, coverage is uneven across readers.

PDF417 (ISO/IEC 15438) is a stacked linear barcode used on US driver's licences, passports, FedEx airbills, and AAMVA-encoded ID cards. Holds up to ~1,800 ASCII characters. Not a QR; QR-only styling is disabled.

Use for legitimate purposes only: AAMVA parser testing, kiosk & age-gate development, accessibility tools, and demoing AAMVA workflows. Producing a counterfeit government ID is identity fraud and is prosecuted as a felony in every US state. Use real data only when you own the source license, or use synthetic data clearly marked as such.

Renders as a PDF417 barcode following the AAMVA Card Design Standard. Scan it back with this site's scanner to see the structured License Preview parser in action.

Code 128 (ISO/IEC 15417). Variable-length, high-density, encodes the full ASCII set. Used in shipping labels (UPS, FedEx, DHL all use it for their internal tracking), supply chain, and industrial labelling.

Code 39 (ISO/IEC 16388). The original alphanumeric barcode, supported by every scanner ever made. Used in healthcare patient bands, DOD military logistics (LOGMARS), and inventory tagging.

Code 93, Symbol Technologies' more compact successor to Code 39. Mandatory two checksum characters (C and K) make it more reliable on scuffed labels.

Codabar (NW-7), used by US blood banks, FedEx airbills (legacy), libraries (US/CA/EU), and photo finishing. Self-checking; does not require a check digit.

EAN-13 / GTIN-13, global retail product identifier. Used outside North America (which uses UPC-A) on every retail consumer product. Use the 12-digit GS1 number; the 13th check digit is computed for you.

EAN-8 / GTIN-8, compact retail product identifier for small packages where EAN-13 won't fit (chewing gum, batteries, etc.).

UPC-A / GTIN-12, North American retail product identifier. Use the 11-digit GS1 number.

UPC-E, compact 8-digit zero-suppressed variant of UPC-A for small packages.

ITF-14 (Interleaved 2 of 5), GS1's standard for shipping cartons / outer cases. Identifies the product inside (GTIN-14). Used by every major retailer and 3PL warehouse.

Vehicle Identification Number per ISO 3779. Encoded as a Code 39 barcode for compatibility with state DMV scanners, automotive registries, and insurance/title workflows. The 9th character is a check digit (auto-validated, not auto-computed, input invalid VINs are still encoded for testing).

Paste the link from your Payconiq merchant portal, typically https://payconiq.com/t/1/... for transactions or https://payconiq.com/l/1/... for static merchant QRs. Scanned by Payconiq, Bancontact, KBC Mobile, Belfius, ING, BNP Paribas Fortis, and most Benelux banking apps.

EPC QR Code (EPC069-12 / Girocode), the European standard for SEPA Credit Transfer initiation via QR. Supported by most European banking apps including Sparkasse, ING, KBC, BNP Paribas, Rabobank, and all EPC-compliant banks.

Paste the URL to your .pkpass file or Apple Wallet deep link. Scanning opens the pass directly in Apple Wallet on iOS devices.

Paste the Google Wallet save link from the Google Pay API or your pass issuer. Scanning opens the pass directly in Google Wallet on Android devices.

Use this if you want to move a public SSH key (id_ed25519.pub, id_rsa.pub) to another machine by QR. Do not paste a private key (anything labeled PRIVATE KEY, id_ed25519 without the .pub suffix). A QR is not an encrypted channel; if you photograph the scanned screen, the key is on that photo.

Encodes the entire authorized_keys line. Scan to copy/paste the key onto a new machine.

Use this if you're sharing an OpenPGP public key block (-----BEGIN PGP PUBLIC KEY BLOCK-----). Do not paste a private key block (PGP PRIVATE KEY BLOCK). Anyone who scans the code reads the payload; only public material belongs here.

For very long keys, use rMQR landscape or split into multiple QRs. Standard QR caps around ~2KB.

Use this if you're provisioning a WireGuard peer and need to move a .conf to a phone or tablet. The config contains the peer's PrivateKey, treat the QR like the private key itself. Do not screenshot, email, or photograph it; delete the rendered QR from shared screens as soon as the device has imported it. Rotate the key if the QR is ever captured by a camera that isn't the target device.

The official WireGuard mobile apps scan these directly. Never include your private key in a printed QR, only digital sharing.

Use this if your WebAuthn server issued a FIDO:/ URI for cross-device passkey sign-in, or if you want a QR that opens your passkey-management page. Do not use this to "create" a passkey, the URI is issued by your relying party; we only wrap it as a QR.

Use this if your healthcare provider, state health department, or health-wallet app gave you a shc:/ URI (vaccination record, lab result, discharge summary, prescription) and you want to share it as a QR code. Do not use this to "create" a health card, the cryptographic signature is issued by the health authority; we only wrap the URI as a QR.

The URI starts with shc:/ followed by digits. If your card is chunked (shc:/1/2/..., shc:/2/2/...), paste one chunk at a time and generate one QR per chunk, SHC verifiers scan them in sequence. Single-chunk payloads fit in a V22 QR (~1,191 digits).

Use this if you're a brand owner preparing for the GS1 Sunrise 2027 cutover or you need a single code that carries product identity + batch/expiry/serial. Do not use as a standalone marketing QR, retailers' POS systems will treat it as inventory data first, URL second.

GS1 Digital Link, the Sunrise 2027 successor to EAN-13. Resolver domain defaults to id.gs1.org. GTIN check digit is validated live.

Use this if you're a manufacturer or importer preparing for the EU Digital Product Passport (DPP) mandate, operational 19 July 2026 under ESPR Regulation (EU) 2024/1781. Each individual product instance sold in the EU needs a scannable QR or Data Matrix resolving to its DPP record. Do not use this as a marketing QR, the URL should resolve to structured DPP data (JSON-LD), not a landing page.

The QR encodes a GS1 Digital Link URL pointing to your DPP record, the same URI syntax as GS1 Digital Link (Article 10 mandate explicitly references it). Your resolver must return structured DPP data (GS1 Digital Link resolver or custom JSON-LD endpoint) and the unique identifier must comply with ISO/IEC 15459:2015.

Paste the share link from the Spotify app, or just the ID. We build the open.spotify.com URL automatically.

Format depends on platform, for Mastodon use @user@instance, for Bluesky use handle.bsky.social, for Nostr paste the npub key.

Geo URI (RFC 5870) opens directly in any maps app on the device (Google Maps, Apple Maps, OsmAnd, etc.) without picking a vendor.

Standard BitTorrent magnet link. Scanned by any BitTorrent client that supports URI scheme handlers.

Entered in your local timezone. Saved as UTC so anyone who scans the QR sees the right wall-clock time in their own timezone.

Scanning the QR opens the native calendar app with a Subscribe prompt. Standard webcal:// URI scheme.

Your entire bio page is encoded into the QR's URL hash, no backend, no account, no tracking. The /bio/ page decodes and renders it client-side.

Paste the 11-character video ID, a youtu.be URL, or a youtube.com/watch URL. We normalize to youtu.be/{id}.

Opens the Apple Music app (or the web player) directly to the song, album, playlist, or artist. Storefront controls which country's catalog is used.

The slug in your Yelp URL after /biz/. Scanning opens the Yelp Write A Review page.

The d + numeric ID from your TripAdvisor listing URL. Scanning opens the Write Review page.

Routes happy customers to your public review page and unhappy ones to a private channel. The branching happens in the user's browser via a hash splash at /review/, with no backend and no tracking. Important: Google's review-gating policies prohibit hiding negative reviews. Use this only to collect private feedback in addition to allowing all customers to leave a public review if they choose.

Tries the deep link first; if the app isn't installed, shows the right store button (App Store on iOS, Play Store on Android). On desktop, opens the web fallback. OS detection happens at /app/, no backend.

Paste any meeting invite link. For Zoom, Google Meet, and Teams we extract the canonical join URL automatically.

If a URL is provided, the QR opens the page with your promo code appended as ?code=YOURCODE. Without a URL, the QR encodes the plain promo code text.

Requires the Venmo mobile app. Desktop browsers will redirect to venmo.com instead.

Use this if you want to share your Zelle-registered email or US phone number as a scannable contact card. Note: Zelle has no universal QR URI scheme, scanners open your chosen contact method; the payer still initiates the transfer from their own banking app. This QR is a convenience, not a direct-pay link.

Zelle is built into every major US bank app (Chase, Bank of America, Wells Fargo, Capital One, Citi, and ~2,000 others). This QR encodes a mailto: or tel: that opens the recipient's contact card. The payer then opens their banking app, taps Zelle, and pastes the email / phone, the actual transfer happens bank-to-bank, never through us.

e₹ / Digital Rupee, the RBI's retail CBDC, live via pilot banks since December 2022. QRs share UPI-style VPAs with an @{bank}digital suffix (e.g. @icicidigital, @hdfcdigital). Interoperable with the existing UPI QR landscape since October 2023.

Use this if you want a reusable Lightning receive QR. BOLT12 offers (lno1...) don't expire and can be scanned repeatedly, unlike BOLT11 invoices. Not all Lightning wallets support BOLT12 yet (Phoenix, Core Lightning, LNDk, Zeus partial); check your wallet before handing out printed QRs.

BOLT12 "offers" are the reusable successor to BOLT11 Lightning invoices, no per-payment re-issuance, no 1-hour expiry. Generated server-side by Core Lightning (lightning-cli offer), LNDk, or Strike. Our QR is a passthrough.

Use this if you're sharing a Monero receiving address or subaddress to accept a payment (monero:<address>?tx_amount= format). Do not paste a seed phrase, view key, or spend key, those control the wallet, not a single payment. If privacy matters for the amount, use a subaddress: regenerate it per recipient so on-chain observers can't link payments.

Monero (XMR) is the largest privacy-by-default cryptocurrency. QR emits a monero: URI per the community-standard scheme; GUI and CLI wallets, Cake, MyMonero, Feather, and Monerujo all parse it.

Use this if you're printing the onboarding QR for a Matter-certified smart-home device (light bulb, sensor, lock, thermostat). The code admits the device into any Matter ecosystem, Apple Home, Google Home, SmartThings, Alexa, Home Assistant. Do not share once the device is paired, anyone with the code can commission it into a fresh fabric.

Matter QR payload (Connectivity Standards Alliance spec). Format is MT: + base38-encoded CBOR. Manual pairing code (11 digits) is the fallback for devices without a QR. Every Matter-certified product is shipped with one from the manufacturer.

WalletConnect v2 (now called Reown) URI. Generated by the dApp when a user clicks "Connect Wallet". Scanning with MetaMask, Trust, Coinbase Wallet, Phantom, Rainbow, Zerion, and 300+ other wallets completes the pairing. Session-specific, URIs are single-use.

NFT claim / mint URLs from thirdweb, Reown, Zora, Manifold, or any chain-aware frontend. Scanning opens the claim page in the user's browser; WalletConnect or injected provider handles the on-chain mint. Works across Ethereum, Base, Polygon, Optimism, Arbitrum, Zora, Solana (scheme-dependent).

Tailscale auth-key URL (ephemeral or reusable) from the admin console. Scanning on a new device triggers the auth flow. Works for Tailscale, Headscale (self-hosted), and compatible forks. Don't publish reusable keys in public QRs, anyone can join your tailnet.

Works for any ActivityPub-compatible server (Mastodon, Pleroma, GoToSocial, Akkoma). Profile URL for sharing; OAuth authorize link for signing into a third-party app.

Use this if you're printing a pet tag, key-chain sticker, laptop label, water-bottle decal, or anything else you want returned if lost. Scanner sees an "if found" contact prompt; owner is never exposed until they choose to respond.

Unified QR, modern Bitcoin wallets pick the Lightning route for small/fast payments and fall back to on-chain. Recommended format for Bitcoin receivers.

Local uploads stay in your browser and only appear on the printed card. MeCard QR data has no photo field.

MeCard is a simpler alternative to vCard, preferred by some Android devices

Micro QR capacity: 35 digits, 21 uppercase alphanumeric, or ~15 bytes (lowercase/URLs). Best for short codes, serial numbers, and IDs. For URLs, use standard QR instead.
