ABOUT THIS TOOL

What can you do with QR codes?

Generate a QR code from a URL or text, or read content from an existing image. These operations help share links and inspect codes. A QR code stores the entered content; whether a link opens depends on its target URL.

Three steps to get it done
  1. Choose generation or reading.

  2. Enter a URL or text, or load a QR code image.

  3. Download the generated code or check the decoded content.

QR codes FAQ

Will a code update if its URL changes?

No. Generated codes contain fixed content. Changes to a URL do not rewrite the image.

How can scanning success be improved?

Use strong contrast, adequate size, and clear margins. Test the export with the target device.
