Frequently Asked Questions

Is it free?
Yes, no account needed.

Does my data get sent to a server?
No, the QR code is generated entirely in your browser.

Should I download PNG or SVG?
SVG for print or enlarging (vector, no quality loss), PNG is fine for screens and sharing.

Do I need to sign up?
No.

Does the QR code I generate expire?
No, it's valid indefinitely — it encodes your data directly, there's no redirect or tracking server in between.

Can I customize the colors, or is it just black and white?
Yes — set custom foreground and background colors with the color pickers, and pick from three size presets (200px, 400px, 800px) before downloading.

Will the QR code still scan reliably if I change the colors or paste a lot of text?
Keep good contrast between the foreground and background colors for reliable scanning, and note that longer text creates a denser code — for long URLs, consider using a shortened link instead.

Which devices and browsers does it work on?
Any recent version of Chrome, Firefox, Safari, or Edge, on desktop or mobile — the code it generates can be scanned by the built-in camera app on any modern smartphone.
