How to make a QR code for a link, email, or Wi‑Fi network
QR codes are just text with a 2D barcode around them. The ToolNest generator builds that image locally.
Choose the payload type
Use Text/URL for https links. Use Email for a mailto with an optional subject. Use Wi‑Fi for a WIFI:WPA string phones can join from the camera.
Print size
512×512 is safer for posters. Test-scan from the distance a person will stand. Error correction is level H, which survives some dirt and crop, not a folded-in-half flyer.
Questions
Can I style the QR with a logo in the middle?+
Not in this tool. Adding a logo can break scans if it covers too many modules.
