Usage and limits
Enter a URL or text, choose correction level and size, then view the result. Input is limited to 1,024 UTF-8 bytes; output is 128–1,024px. Codes use black and white with a four-module quiet zone and require at least two pixels per module. Scan the saved code on a real device. This is a static QR: regenerate it to change its content. Link safety is not checked, and input is not sent to a server.
