About
Tessera generates digital mosaics (QR codes) from any text or URL, with full control over how they look and where they end up.
Features:
- Live preview as you type
- Custom foreground color, with a warning if contrast is too low to scan reliably
- Four error correction levels (Low, Medium, High, Quartile)
- Export as PNG or SVG
- Copy to clipboard from the menu or with a single click on the mosaic
- Persistent preferences for default color and error correction level
