Encode any non-empty text or URL as a QR code, with L/M/Q/H error correction, scale, and quiet-zone controls.
Common uses
- Create QR codes for posters, instructions, or presentations.
- Turn short text or URLs into images that are easy to print and share.
How to use it

- 2.Choose the error-correction level, scale, and quiet zone.
- 3.Generate the code, then copy the data or download PNG / SVG.
Limits and notes
- The payload is limited to about 4,000 UTF-8 bytes; longer content creates denser codes, so scan the printed result before relying on it.
Frequently asked questions
What can I encode?
You can encode non-empty text or a URL; the tool does not test whether a URL is reachable.
How should I choose error correction?
L through H provide increasing recovery capacity but also add modules. Choose based on the print conditions and available size.
