What we can repair

Stage 1 · Free

Fixed on the spot

Blurry, low-contrast, slightly smudged or crumpled – cleaned up right in your browser, free.

We keep working on it

Badly damaged, but part of the structure survives. Register, submit – we notify you the moment we can recover it.

Stage 3 · Honestly gone

Physically unrecoverable

Too much is missing – e.g. a destroyed corner marker. That information is no longer in the image. We tell you straight.

Frequently asked questions

How does online QR code repair work?
Semacode converts the image to grayscale, stretches contrast, sharpens the edges and applies an optimal threshold, then a real decoder reads the content. It all happens on your device — nothing is uploaded.
What damage can be repaired?
Blur, low contrast, fading, creases and a missing quiet zone are usually repairable. A destroyed corner marker or a large missing area is not — that information is physically gone.
Does QR code repair cost anything?
Instant repair in your browser is free. For codes that are too damaged, leave your email and we'll let you know when we can recover them.
