Anything expressible as text: URLs, plain sentences, phone numbers, or structured payloads like vCard contacts and WIFI network strings. The format tops out at 4,296 alphanumeric characters in theory, though codes get dense and fussy long before that.

It's free with no watermark, no account, and no expiry. The codes are static, meaning the data lives inside the image itself rather than behind a redirect service, so nothing can be turned off or put behind a paywall later.

SVG for anything going to a printer, because vectors scale to poster size without blurring the modules. PNG suits screens, documents, and quick shares. If you're unsure of the final print dimensions, SVG is the safe pick.

Yes, within limits. Scanners want strong contrast and expect dark modules on a light field, so a navy code on cream works while yellow on white fails. Avoid inverting the scheme entirely; light modules on a dark background trip up plenty of readers.

A working rule of thumb is one tenth of the scanning distance. A code scanned from 20 centimeters away should be at least 2 centimeters wide, while a poster read from across a room needs 20 centimeters or more. When in doubt, print a test sheet.

The usual suspects are weak contrast between the two colors, too much encoded data making the modules tiny, or glare from glossy paper. This tool always draws a quiet zone margin around the code, so at least that classic mistake is handled for you.

No. The code is drawn onto a canvas element inside your browser, and downloads are generated from that same canvas. URLs, phone numbers, or anything sensitive you encode never crosses the network.

Aim for under 300 characters. Every extra character adds modules, and denser grids demand bigger prints and better cameras. For long URLs, run them through a shortener first and encode the short form instead.
