Do these QR codes expire?

No. They are static codes: the information is inside the QR itself, with no redirect through any server, so they work forever.

Which error correction level should I use?

M (15%) is fine for most uses. Use Q or H if the code will be printed on surfaces that can get scratched, or if you plan to put a logo over it.

Can I change the colors?

Yes. Keep a dark color on a light background with good contrast; inverted or low-contrast codes may not scan.

What size should I print?

At least 2 × 2 cm, and about one tenth of the scanning distance: for a poster read from 2 meters, around 20 cm.

Are my files uploaded to a server?

No. Everything is processed inside your browser and your files never leave your device. There is no upload, no queue and no temporary storage, so the tool keeps working even if you go offline after the page has loaded.

Yes. There is no sign-up, no watermark and no daily limit. The site is funded by a few unobtrusive ads around the tools, never inside your files.
