How to use

This tool belongs to the “Utilities” category.

  1. 1Text to QR: paste a link or text (up to about 800 characters works best), set the size and the error-correction level L/M/Q/H, then download the image.
  2. 2Text compare: put the two versions in the boxes above and additions and deletions are highlighted live. Ctrl / Cmd + Enter runs it, Esc clears both.
  3. 3ICO maker: start from an image or straight from one to three characters or an emoji; it exports several sizes and previews the favicon.

Frequently asked questions

Can I encode very long content in a QR code?

It will generate, but the module grid gets so dense that cheap printers and older cameras struggle. Shorten the link first, or split the content into several codes.

Which error-correction level should I pick?

M covers ordinary use. Choose Q or H when a logo sits on top or the code may get scratched - the same content then needs a larger image.

Is my text uploaded when comparing?

No. The comparison happens entirely in the browser; the text never leaves your device.
