Let guests join your Wi-Fi with one scan instead of typing a long password. The code uses the standard WIFI: format that iPhone and Android cameras recognize, for WPA/WPA2, WEP, open and hidden networks; print it for a café table, a rental or a guest room.
How to use
- Pick what the code should contain: a link, text, Wi-Fi, a contact, email, SMS, phone number or location.
- Fill in the fields. The QR code updates as you type.
- Adjust colors, margin and error correction, or add a logo in the center.
- Download a PNG in the size you need or a vector SVG for print, or copy the image. To read a code, open Scan and use the camera or a picture.
- Codes are static: they contain the data itself, never expire and don’t track scans.
- Error correction L/M/Q/H lets a code survive 7/15/25/30% damage. Higher levels make the code denser.
- Keep strong contrast: a dark code on a light background scans everywhere.
- Wi-Fi codes follow the standard WIFI: format that iPhone and Android cameras understand. Your password never leaves the device.
- The scanner works offline in your browser. Camera access is only used while scanning.
Static codes that never expire
A static QR code stores the data itself: the link, the Wi-Fi details or the contact card is encoded in the pattern, so the code keeps working as long as the content is valid, with no account, subscription or redirect in between. The trade-off is that you cannot change the target after printing; if you need that, print a link to a page you control.
Error correction and logos
QR codes use Reed–Solomon error correction in four levels: L recovers about 7 % damage, M 15 %, Q 25 % and H 30 %. Higher levels make the pattern denser but let the code survive scratches, dirt or a logo in the middle. When you add a logo, use Q or H and keep the logo small.
Longer content also makes the code denser, so short URLs scan more easily from a distance.
Printing and scanning
Keep strong contrast: a dark code on a light background works with every scanner, while light-on-dark or low-contrast colors can fail. Leave a quiet zone (margin) of about four modules around the code. As a rule of thumb, the code should be at least 2 cm (0.8 in) wide for close scanning, and larger for posters seen from a distance. Use SVG for print so edges stay sharp.
Frequently asked questions
Do these QR codes expire?
No. They are static codes that contain the data directly, so they keep working forever and nothing depends on this website.
Is the QR code generator free for commercial use?
Yes. There are no limits, sign-ups or watermarks, and you can print the codes on packaging, menus, flyers and business cards.
Can I add a logo to a QR code?
Yes. Add a logo in the center and set error correction to Q or H so the code still scans with part of it covered. Test the result with a few phones before printing.
How do I make a QR code for Wi-Fi?
Choose Wi-Fi, enter the network name and password and the security type. Phones that scan it offer to join the network, and the password never leaves your device while you make it.
Can I track how many people scan my code?
No. Static codes have no tracking. If you need statistics, encode a link with campaign parameters or to a page whose visits you measure.
How do I scan a QR code with this site?
Open Scan and allow the camera, or choose a photo or screenshot. The decoded content is shown field by field, ready to open or copy, and images stay on your device.
