Using UUID Generator for printed materials
How to size and format a identifier so it actually scans / works when printed. Browser-based, free, no signup, runs entirely on your device.
Generating a identifier sounds like it should require an app — and historically it did. UUID Generator runs the same thing in your browser tab, with one tap and no signup.
Launch the tool: UUID Generator — No upload, no signup, no daily limit.
UUID Generator for printed materials
Print is where identifier generation gets specific. The identifier needs to scan reliably from a few inches away, under uncontrolled lighting, possibly slightly crumpled or smudged.
Sizing rules
- Minimum size for scanning at arm's length: 2 cm × 2 cm (about 0.8 inches).
- For posters meant to be scanned from across a room: at least 10 cm × 10 cm, scaled up linearly with distance.
- Always include the quiet zone — the empty border. Without it, scanners struggle.
Print-specific tips
Generate at the largest size you'll need, then scale down in the layout — never up. PNG with high error-correction is the safest format for press output. Test with a real phone before you commit to the print run.
Run it in your browser
Browser-only. Nothing is sent to a server.
Frequently asked questions
Is UUID Generator truly free?
Yes. No signup, no daily cap, no watermark. The site is supported by ads, not subscriptions.
What format does UUID Generator output?
UUID Generator offers PNG (for print), SVG (for web), and plain text (for embedding) where applicable.
Will my identifier work after UUID Generator shuts down?
Yes — once generated, a identifier is a standalone artefact. It doesn't depend on UUID Generator continuing to exist.
Does UUID Generator store my generated identifier?
No. UUID Generator generates everything in your browser; nothing is uploaded, saved, or sent.
