Links, WiFi, plain text — drawn with shapes and colors you’d actually put on a poster. Free, no signup, never expires, and generated in your browser: nothing you type leaves the page.
Never. The code you download contains your data itself — there is no shortlink, no redirect through our server, no account it belongs to. Services that “expire” QR codes are selling dynamic redirects; a static code like this one works as long as ink and paper do.
No. The code is computed and drawn entirely in your browser — content, colors and logo included. Nothing you type here reaches our server, which is also why the tool is fast.
Yes, within reason — QR readers binarize the image, so shapes matter less than contrast. The rules of thumb: dark code on light background (not the reverse), contrast ratio 4:1 or better, quiet zone ≥ 4 modules, and if you add a logo keep it near 20% with error correction H. The generator warns you live when a choice threatens scannability — and always test the printed code with a phone camera before ordering 5,000 stickers.
SVG for print and design work — infinitely sharp, editable in Inkscape or Illustrator, tiny file. PNG for pasting into documents and slides; 1024 px covers most uses, 2048 px for large prints. Transparent background works in both.
QR codes carry redundancy so damaged or obscured codes still read. L survives 7% damage, M 15%, Q 25%, H 30%. Higher levels make denser codes. M is right for clean digital use; H when a logo covers the middle or the code lives outdoors.
