qrxel ☁️

quirky qr-code pixel art (/ˈkwɜːk.səl/)

qrxel is a local-first, mobile-first PWA for turning QR codes into tiny pixel-art canvases. Upload or take a photo of a QR code, preserve its exact module grid, paint color layers on top, add labels for the shapes you see, and export or post the result.

• Exact QR module extraction from uploaded images, including non-aligned photos and inverted light-on-dark codes.
• Tap/drag painting with overlapping color layers, per-layer visibility, undo, reset, invert, zoom, and pan.
• Marker labels attached to color layers so you can point out the shapes you see.
• SVG, PNG, compact project JSON, and Bluesky posting with qrxel-first image order.
• Offline-ready PWA with all processing kept local in the browser.
