A personal QR code generator running at qr.seraph.ws.
Built in Rust with Axum. Generates QR codes client-side as SVG or high-res PNG, with optional logo overlay and a print mode (black on white). The SVG preview updates live as you type.
Uses the qrcode crate with high error correction (Level H) to keep codes scannable even with a logo in the centre. PNG export is rendered at 40px per cell — large enough for print without upscaling artifacts.
