Frequently asked questions

Can I use the data URL format in HTML directly?

Yes — format=dataurl returns a base64-encoded PNG you can embed as an <img src='data:image/png;base64,...'> without a separate request.

What error correction level should I use?

H (30%) if you plan to overlay a logo on the QR code. M (15%) for clean codes without overlay.

Is there a size limit?

Size must be between 64 and 2048 pixels. 300px is good for web; 600px+ for print.
