Free Lost & Found QR Code 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.

Mikä tahansa ladattava tiedosto — asennusohjelma, arkisto, asiakirja, datasetti. Isännöi missä tahansa; koodaamme URL:n. Käyttäjän selain käsittelee latauksen omien MIME-tyypisääntöjensä mukaan.

JPEG, PNG, WebP, GIF tai HEIC — isännöi missä tahansa. Mobiiliselaimet avaavat kuvan koko näytölle; työpöytäselaimet näyttävät sen upotettuna.

YouTube- ja Vimeo-URL:t avautuvat natiivisti sovelluksissaan puhelimissa. Suorat .mp4-/.webm-tiedostot avautuvat upotettuna kaikissa moderneissa selaimissa.

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.

Restaurant / cafe / bar menu — point to a PDF, an HTML menu page, or your online-ordering platform (Toast / Square / DoorDash / Uber Eats). Print on table tents, host signs, or window stickers. Pro tip: use a frame ("Scan our menu") so customers know what to do.

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.

Paikalliset lataukset pysyvät selaimessasi ja näkyvät vain tulostetulla kortilla. QR-data käyttää yllä olevaa URL-osoitetta.

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.

Punainen Sveitsin lippu lisätään automaattisesti QR-koodin päälle — sveitsiläiset pankit vaativat sen.

Liitä BOLT11-lasku (lnbc...) tai Lightning-osoite. Lisäämme lightning:-URI-etuliitteen, jotta mikä tahansa Lightning-lompakko voi skannata sen.

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.

Yhteensopiva Google Authenticatorin, Authyn, 1Passwordin, Bitwardenin ja minkä tahansa vakio-TOTP-sovelluksen kanssa.

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 -aktivointikoodi LPA-spesifikaation mukaan. iOS 17.4+ ja Android 13+ skannaavat ne suoraan eSIM-profiilia varten.

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.

Renderöi PDF417-viivakoodina AAMVA Card Design Standard -standardin mukaisesti. Skannaa takaisin tämän sivuston skannerilla nähdäksesi jäsennellyn ajokortin esikatselu-parserin toiminnassa.

Code 128 (ISO/IEC 15417). Muuttuva pituus, korkea tiheys, koodaa koko ASCII-merkistön. Käytetään lähetyslipoissa (UPS, FedEx, DHL käyttävät sitä sisäiseen seurantaan), toimitusketjussa ja teollisessa merkinnässä.

Code 39 (ISO/IEC 16388). Alkuperäinen aakkosnumeerinen viivakoodi, jota tukee jokainen koskaan valmistettu skanneri. Käytetään terveydenhuollon potilasrannekkeissa, sotilaallisessa logistiikassa (LOGMARS) ja varastoinnin merkinnässä.

Code 93 — Symbol Technologies'n tiiviimpi Code 39:n seuraaja. Pakolliset kaksi tarkistussummamerkkiä (C ja K) tekevät siitä luotettavamman naarmuuntuneissa tarroissa.

Codabar (NW-7) — käytetään Yhdysvaltain verenpankeissa, FedEx-ilmarahtilapuissa (perinteinen), kirjastoissa (USA/CA/EU) ja valokuvaamisessa. Itsestään tarkistava; ei tarvitse tarkistusnumeroa.

EAN-13 / GTIN-13 — maailmanlaajuinen vähittäiskaupan tuotetunniste. Käytetään Pohjois-Amerikan ulkopuolella (joka käyttää UPC-A:ta) kaikissa kuluttajatuotteissa. Käytä 12-numeroista GS1-numeroa; 13. tarkistusnumero lasketaan puolestasi.

EAN-8 / GTIN-8 — kompakti vähittäiskaupan tuotetunniste pienille pakkauksille, joihin EAN-13 ei mahdu (purukumi, paristot jne.).

UPC-A / GTIN-12 — Pohjois-Amerikan vähittäiskaupan tuotetunniste. Käytä 11-numeroista GS1-numeroa.

UPC-E — kompakti 8-numeroinen nollatiivistetty UPC-A:n muunnelma pienille pakkauksille.

ITF-14 (Interleaved 2 of 5) — GS1:n standardi lähetyslaatikoille/ulkopakkauksille. Tunnistaa sisällä olevan tuotteen (GTIN-14). Käytetään kaikissa suurissa jälleenmyyjissä ja 3PL-varastoissa.

Ajoneuvojen tunnistenumero ISO 3779:n mukaisesti. Koodattu Code 39 -viivakoodina yhteensopivuuden vuoksi valtion DMV-skannerien, autorekisterien ja vakuutus-/omistajuustyönkulkujen kanssa. 9. merkki on tarkistusnumero (automaattisesti vahvistettu, ei automaattisesti laskettu — virheelliset VIN-syötteet koodataan silti testausta varten).

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.

Koodaa koko authorized_keys-rivin. Skannaa kopioidaksesi avaimen uuteen koneeseen.

Hyvin pitkille avaimille käytä vaakasuoraa rMQR:ää tai jaa useaan QR-koodiin. Standardi QR rajoittuu noin ~2 kt:iin.

Viralliset WireGuard-mobiilisovellukset skannaavat nämä suoraan. Älä koskaan sisällytä yksityistä avainta tulostettuun QR-koodiin — vain digitaaliseen jakoon.

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 on moderni verkkoystävällinen vaihtoehto EAN-13-viivakoodille vähittäiskaupan tuotteille. Selvittäjän verkkotunnuksen oletusarvo on id.gs1.org, mutta voit käyttää omaasi.

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.

Liitä jakolinkki Spotify-sovelluksesta tai pelkkä tunnus. Rakennamme open.spotify.com-URL-osoitteen automaattisesti.

Muoto riippuu alustasta — Mastodonissa käytä @käyttäjä@instanssi, Blueskyssä handle.bsky.social, Nostrissa liitä npub-avain.

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/ — no backend, 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.

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.

Satispay — Italy's licensed payment-institution mobile wallet. Accepted by 300,000+ Italian merchants. Customers scan the QR from the Satispay app; no card data, no typing PIN.

Use this if you're piloting Drex (Brazil's wholesale/retail CBDC, launched 2026 by Banco Central do Brasil on a Hyperledger Besu DLT). Drex settles via the existing Pix infrastructure; most merchant integrations accept the same Pix EMVCo-style QR with a Drex flag.

Drex — Brazil's tokenised central bank digital currency, Phase-1 live 2026. Settles through existing Pix QR infrastructure during the transition. For pure-Pix transfers, use Pix.

Use this if you're testing Digital Euro pilot rails (ECB preparation phase, 2023–present; live retail issuance decision expected late 2026). Format follows EPC / SCT-Inst QR patterns with a CBDC flag. Not yet a production payment method — pilot participants only.

Digital Euro — the ECB's proposed retail CBDC. Preparation phase runs through Oct 2026; live issuance pending Governing Council decision. For standard euro bank transfers, use SEPA or EPC Girocode.

Digital Ruble — Bank of Russia CBDC. Pilot banks began retail rollout September 2026; mandatory distribution via commercial banks scheduled phase-in through 2027. Each wallet address is issued by a participating bank.

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.

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.

No account, no tracking, no service that can paywall your tag. The QR goes straight to your chosen contact method with a pre-filled "I found this" subject line. Works for pet tags, luggage, bike locks, cameras, anything with a visible printable surface.

PayID on Australian välittömän maksamisen osoituspalvelu. Toimii kaikkien NPP-yhteensopivien australialaisten pankkisovellusten kanssa.

ZATCA / FATOORA on Saudi-Arabian pakollinen sähköinen lasku-QR-muoto, jota vaaditaan jokaisessa kaupallisessa laskussa vuodesta 2021.

Paikalliset lataukset pysyvät selaimessasi ja näkyvät vain tulostetulla kortilla. MeCard QR -datassa ei ole kuvakenttää.

MeCard on yksinkertaisempi vaihtoehto vCardille, jota jotkin Android-laitteet suosivat

Micro QR -kapasiteetti: 35 numeroa, 21 isoa aakkosnumeerista merkkiä tai ~15 tavua (pienet kirjaimet/URL:t). Parhaiten lyhyille koodeille, sarjanumeroille ja tunnuksille. URL-osoitteille käytä tavallista QR:ää.

Suorakaiteen muotoinen Micro QR — kapea, leveä muoto, joka sopii ihanteellisesti koeputkiin, rannekkeisiin ja lipputarroihin. Jopa 361 merkkiä.
