A QR code is text stored as a grid of dark and light squares called modules.
Error correction adds spare codewords so a scanner can repair modules it read wrongly.
A QR code is a short piece of text, usually a web address, drawn as dark and light squares.
Everything runs in your browser. Nothing is uploaded.
One line per code, optionally with a filename before a comma.
Paste your text and see which version (size in modules) you need at each error-correction level.
Every square in a QR code has a job. This tool colours them so you can see which is which.
Guides with a good and a bad example for every rule.
Minimum size is one tenth of the scan distance. Arm's length needs 2 cm; a poster read from 2 m needs 20 cm.
Dark modules on a light background, a four-module quiet zone, and a logo under a quarter of the area. Everything else is decoration.
Put the logo dead centre, set error correction to H, and keep it under about a quarter of the code's area.
Yes. Signed-in users can make unlimited static QR codes with no ads, no watermark and no expiry. Pro adds dynamic codes, analytics, AI design and print export.
Static codes never expire; the data is inside the code itself. Dynamic codes keep redirecting to their last destination even if Pro ends; editing them needs Pro. Any code can be duplicated as a static one.
iPhone and iPad. The site works everywhere and its free tools run in any browser.
Yes, on the free plan. The scannability check warns you if a logo is too large or the contrast is too low.
