Tip: right-click any spot on Google Maps and copy the coordinates
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.
Compatible with Google Authenticator, Authy, 1Password, Bitwarden, and any standard TOTP app.
Encodes the entire authorized_keys line. Scan to copy/paste the key onto a new machine.
For very long keys, use rMQR landscape or split into multiple QRs. Standard QR caps around ~2KB.
The official WireGuard mobile apps scan these directly. Never include your private key in a printed QR — only digital sharing.
GS1 Digital Link is the modern web-friendly alternative to the EAN-13 barcode for retail products. Resolver domain defaults to id.gs1.org but you can use your own.
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.
Paste a full RFC 5545 iCalendar payload — supports multiple events, alarms, recurring rules. Most calendar apps import the QR directly.
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.
Rectangular Micro QR — a narrow, wide format ideal for test tubes, wristbands, and ticket strips. Up to 361 characters.

Renders behind the QR at reduced opacity. Auto-forces EC=H so the QR still scans through the photo.
Batch Generation
Upload a CSV to generate up to 500 QR codes in a single batch. Each row becomes its own QR — pick a template or override 21 properties on a per-row basis: colors, frames, dot/eye/eyeball styles, gradients, transparency, size, error correction, format, built-in logo, and more.
21 columns: type, data, filename, frametext, frame, template, fgcolor, bgcolor, size, ec, dotstyle, eyestyle, format, logo, gradient, g2, gtype, gangle, transparent, eyeball, eyecolor. Only type and data are required. Use | to separate fields inside data (e.g. ssid|password|WPA).
All 20 QR types supported, including URL, WiFi, vCard, MeCard, Email, SMS, Event, Location, UPI, SEPA, PayPal, Crypto, Micro QR and rMQR. Download the sample CSV to see every column, all 40 templates, 11 frame styles, and the 12 built-in logos in action.
Save the entire QR — type, all field values, style, frame, logo, business card design — as a single .qr.json file. Load it later to recreate everything in one click.

iCalendar vs single-event Event QR
The Event QR type takes one event and emits a minimal VEVENT block. The iCalendar QR type takes a complete .ics file payload — multiple events, VTIMEZONE blocks, VALARM reminders, RRULE recurrence, attendee lists, attachments, X- extensions. The full RFC 5545 standard.
Use this for sharing a conference schedule (one .ics with 30 sessions), a recurring meeting that already exists in your calendar, an event with custom alarms, or any case where the simple Event UI isn't enough.
Frequently Asked Questions
Which calendar apps import these QR codes?
Apple Calendar, Google Calendar (via Lens or Files), Outlook, Thunderbird, Fantastical, BusyCal, Zimbra, Nextcloud Calendar, GNOME Calendar, KOrganizer, Etar, DAVx5. Most QR scanners drop the text into the clipboard or hand off to a calendar import flow.
How big can the .ics be?
QR codes hold up to ~2,950 bytes of text. A single VEVENT is usually 200-500 bytes. A 30-session conference schedule is tight — switch to rMQR or split into multiple QRs for very large payloads.
Do I need to include VTIMEZONE blocks?
If your DTSTART/DTEND use floating local times (no Z suffix and no TZID), no. If you use TZID parameters, you must include the matching VTIMEZONE block per RFC 5545. Apple Calendar is strict about this; Google Calendar is more lenient.
Can I include attendees and RSVP?
Yes — ATTENDEE properties with RSVP=TRUE are encoded verbatim. Whether the importing app actually sends an RSVP depends on the app and the user's account.
What about VALARM (reminders)?
Fully supported. Encode the VALARM stanza inside your VEVENT and the importing app will set the reminder.
Can I encode RRULE for recurring events?
Yes. Standard RRULE syntax (FREQ=WEEKLY;BYDAY=MO,WE,FR;UNTIL=...) is encoded verbatim. The importing app handles the recurrence.
Will the QR include attachments?
ATTACH properties can hold a URL or a base64-encoded blob. URL ATTACHs are tiny and fit fine. Base64 ATTACHs are huge — use the URL form for anything over a few hundred bytes.
