qrok

QR code generator that runs entirely in your browser.

How it works

Type or paste text. QR codes update as you type. Customize size, error correction level, and colors. Download as SVG or PNG.

• Instant generation: updates in real-time
• Customizable: size (200×200 to 800×800), error correction (L/M/Q/H), foreground/background colors, transparent backgrounds
• SVG + PNG export: download in vector or raster format
• All local: everything happens in your browser
