How to use
Type a link or any text and the QR code updates as you type. Switch to Wi-Fi to make a code that lets phones join your network without typing the password. Download it as PNG for documents and chat, or SVG for print, where it stays sharp at any size.
Do these QR codes expire?
No. The content is stored in the code itself, not behind a redirect link, so it works forever and nobody tracks the scans. The flip side is that the content can’t be changed after printing.
Tips for reliable scanning
Keep a dark foreground on a light background, leave the white margin around the code, and print it at least 2 cm (about 1 inch) wide. Use error correction Q or H if the code may get scratched or you plan to place a logo over it.
