Notes

Notes

Important points are grouped with reasons so you can make decisions before using the tool.

Check

Use a readable color combination

A weak contrast between the foreground and background can make the QR code hard to scan. Start with a dark foreground and a light background.

Check

Keep enough margin for print and placement

Leaving enough space around the QR code helps scanners detect it more reliably on paper and on screen.

Check

Review the destination background when using transparency

A transparent background changes depending on where you place the QR code. Check the preview before saving.

FAQ

Questions about QR Code Generator

Questions that make decisions easier before use are summarized first.

Is the input sent outside the browser?

No. QR code generation runs in the browser and the input is not sent externally.

Can I create a QR code from text other than a URL?

Yes. You can create QR codes from short text, notes, or instructions as well as URLs.

Can I save both PNG and SVG?

Yes. PNG is useful for documents and image editing, while SVG is useful for web use and scaling.

Can I make the background transparent?

Yes. Turn on transparency to save a QR code with a transparent background.

Should I change the mask pattern?

Auto is usually best. Change it only when you want to compare the visual result before printing.

Are colored QR codes scannable?

They are easier to scan when the foreground and background have enough contrast. Test with a real device before use.
