About this tool
Turns text, URLs, WiFi credentials, or contact details into a downloadable QR code, with adjustable size, colors, and error-correction level.
When you’d use it
- Putting a link on a printed handout or business card.
- Generating a WiFi QR code for guests instead of reading out a password.
Frequently asked questions
- Does the QR code expire, or point at a service you host?
- No, it encodes your data directly, so nothing is generated or tracked server-side once you've downloaded it.
- What does the error-correction level actually control?
- Higher levels let the code still scan correctly if part of it is damaged, dirty, or obscured, at the cost of a denser pattern. Use a higher level if the code will be printed small or placed somewhere it might get scuffed.
