QR code generator
Make QR codes for Wi-Fi, contacts, links, text, email, SMS and phone numbers. The code is drawn in your browser, so what you type stays with you.

How it works
What you type is turned into the short text format phones understand, such as WIFI: for networks or a vCard for contacts. That text is encoded as a QR code by a small encoder written for this page. It picks the smallest version (1 to 40) that fits, adds error correction at the level you choose, and tries all eight mask patterns to find the easiest one to scan.
Why it stays private
The whole encoder runs in this page. Your Wi-Fi password, phone number or message is never sent anywhere, and nothing is saved when you close the tab. If you like, turn off your connection after the page loads; the tool keeps working.
Questions
Will a Wi-Fi code work on iPhone and Android?
Yes. Both camera apps recognise the standard Wi-Fi QR format and offer to join the network. Hidden networks can be less reliable on some phones.
Which error correction should I pick?
Medium suits most uses. Choose High if the code will be printed small, may get scuffed, or sits behind glass. Higher levels make the code denser.
Do these codes expire?
No. The content is inside the pattern itself, so there is no link to a service that could stop working or track scans.
Why is there a contrast warning?
Scanners need a dark code on a light background with clear contrast. Light-on-dark or pale colours often fail, especially on older phones.
Is it safe to put a Wi-Fi password in a QR code?
Anyone who can scan the code can join the network, so treat a printed code like the password itself. A guest network is a good choice for codes on display.
