QR codes: a quick guide
How it works, supported formats and file limits
Create a QR code for a link, Wi-Fi details or a contact. No account needed.
Will my QR code expire?
No expiry or redirect service. Links must still work. If the details or Wi-Fi password change, make a new code.
PNG or SVG: which should I choose?
Use PNG for sharing and SVG for print. Keep good contrast and test the downloaded code with your phone.
Getting started
- Choose what to share and fill in the details.
- Pick your colours and size, then check the preview.
- Download PNG or SVG and give it a test scan.
Formats and limits
- Create codes for links, Wi-Fi, contacts, email and other supported content types.
- Download PNG or SVG. QR content is limited to 1,200 bytes; long entries may need a larger code.
- Test the downloaded code at its final size before printing or sharing it.
