FAQ

What's the difference between SVG and PNG?

SVG is vector format, can be infinitely scaled without quality loss, suitable for printing and large format. PNG is bitmap format, will degrade when scaled, but has better compatibility.

How to use in web pages?

After generation, click copy button, paste SVG code directly into HTML.

Why recommend high error correction level?

High error correction level ensures QR code remains scannable when partially damaged, improving QR code reliability.
