How to use
- Paste URL/text (≤800 chars; shorter scans easier — shorten long URLs first).
- Pick size: Medium for screens, Large/X-Large for printed posters.
- Pick error level: M (15%) for general use; Q (25%) or H (30%) for dirty/folded prints or logo overlays.
- Colors must stay dark-on-light — low contrast is the #1 scan failure.
- Download PNG or long-press to save; test-scan with two phones before printing.
