Frequently asked questions

How do I fix a QR code online?

Upload a photo of the code. Semacode improves the image and runs a real QR decoder to recover the content, right in your browser — no app and nothing is uploaded.

Why won't my QR code work?

Usually low contrast, blur, a missing quiet zone or damaged modules. Semacode corrects exactly these and tries to make the code readable again.

Is it really free?

Yes — fixing a code online in your browser is free. For codes too damaged to fix automatically, you can send them in and we'll follow up by email.
