Local uploads stay in your browser and only appear on the printed card. The QR data uses the URL above.
More fields (optional)
Address
Social profiles
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.

Why a fediverse handle QR?
Decentralized social means no single company owns your audience — the trade-off is that your handle includes your home server, which is harder to remember and share than a single Twitter username. Mastodon handles look like @user@instance.social, Bluesky handles like user.bsky.social, Nostr identities are 64-character npub strings. None of them fit on a business card without typos.
QR fixes that. Print on a card, a sticker, the back of your laptop. Scan and follow.
Frequently Asked Questions
Which platforms are supported?
Mastodon (any instance), Bluesky (handle.bsky.social or custom domain handles), Threads (Meta's federated network), Nostr (via npub keys), and Matrix (matrix:u/handle:server URIs).
How do I write a Mastodon handle?
Use the @user@instance.social form (with the leading @ optional). We split on @ and build the canonical https://instance.social/@user URL.
What about Bluesky custom domain handles?
If your handle is a domain you control (like 'jay.bsky.team' or 'craigtumblison.com'), enter the full handle. We build https://bsky.app/profile/handle which works for both bsky.social and custom-domain handles.
Why does Nostr use a key instead of a name?
Nostr identities are public keys, not usernames. The npub format is bech32-encoded for human readability. Our QR encodes the nostr: URI scheme with the npub key, which Nostr-compatible apps recognize.
Will the QR work with Threads?
Yes for the public web profile (https://www.threads.net/@user). Threads' federation is partial as of 2026 — some Mastodon servers can follow Threads accounts but the integration is one-way for many features.
Can I encode a Matrix room?
This generator does Matrix user handles (matrix:u/...). For a room, use the URL QR type and encode the matrix.to/#/!roomid:server URL.
What if my handle has special characters?
Most fediverse handles are ASCII. Unicode usernames aren't widely supported on Mastodon; Bluesky allows them but they're rare. If your handle has unusual characters, test the generated QR with a real client before printing.
