FAQs

We have answers to the most common questions that our users ask.

Are these tools genuinely free?

Yes. Upload your file and repair it at no cost. A small number of advanced recovery scenarios — heavily fragmented files, for example — may require a paid upgrade, and we'll tell you upfront if that's the case.

What happens to my file after I upload it?

It's encrypted the moment it leaves your device, processed in a secure environment, and permanently deleted from our servers after 24 hours. We don't store, read, or share your files.

How long does a repair actually take?

Most files are done within two to three minutes. Larger or more severely damaged files can take a little longer — we'll show you a progress indicator so you're never left guessing.

Do I need to install anything?

Nothing. Open the page, upload your file, done.

What if the online tool can't fix it?

It's rare, but some files are too badly damaged for browser-based repair. When that happens, we'll point you directly to the right desktop tool or professional service — whichever fits your situation.
