Tips

Longer or more complex content produces denser QR codes — increase the size to improve scan reliability.
PNG/JPEG are exported via canvas; SVG download is not supported yet.
A larger margin improves scan success, especially on busy backgrounds or in print.
Keep high contrast between dark modules and a light background; avoid inverted colors that hurt scanning.
After generating, test-scan to verify the link works and the content is correct.
