QR Code Generator
URLs & Text
Create downloadable QR codes from URLs or text, adjust the pixel size, and preview the result instantly.
What is this tool?
This QR code generator converts text or a URL into a scannable QR image. QR codes encode data into a two-dimensional matrix of modules, allowing cameras and scanner apps to recover the original value.
The current tool produces a PNG data URL at the selected pixel size. The amount of data, physical print size, contrast, quiet zone, and camera quality all affect scan reliability.
Use it for quick links, event pages, menus, internal labels, slide decks, and prototypes. Always test the downloaded code on the devices and at the size people will actually use.
How to use
- Paste a URL or text value into the input area.
- Adjust the size slider to choose the PNG dimensions.
- Preview the generated QR code.
- Download the image and scan-test it at the final display or print size.
