How MKV repair works here

Our goal is to fix the structure around your video/audio data, not to re-film anything:

1. Upload your corrupted MKV to FixMyFile.ai.
2. Choose Smart Repair and start the job.
3. Our pipeline inspects tracks, headers, and timestamps.
4. We attempt to rebuild a clean MKV or a more universal format like MP4.
5. Download the repaired file and try playing it again in your usual player.

Why MKV files corrupt so easily

MKV is powerful, but that flexibility comes at a cost:

Interrupted downloads or incomplete copies.
Bad sectors on storage devices.
Encoding/export crashes in editing software.
Improper muxing or merging from different sources.

Often, the underlying encoded streams are still there. The container around them—the MKV “wrapper”—is what’s broken, and that’s where tools like FixMyFile.ai focus.

Free to try, donations keep it running

FixMyFile.ai is meant to be the kind of tool you send to a friend at 2 AM when a deadline is on the line. To keep it that way, we:

Let you run repairs without an account.
Don’t watermark or lock your videos.
Rely on optional donations instead of forced subscriptions.

If this page helps you save a stream, recording, or movie rip you care about, consider paying it forward for the next person who panics over a broken file.

MKV repair FAQ

Will you convert my MKV to MP4?

In some cases, yes. If the MKV container itself is the problem, converting to a simpler container like MP4 can make the file playable again.

Can you fix subtitle tracks too?

If subtitle tracks are intact in the file, they may be preserved. If they’re stored in a damaged segment that’s unreadable, recovery may not be possible.

Is there a size limit?

We’re focused on everyday files, not multi-hour uncompressed masters. If you’re unsure, you can still try a repair—it’s free to attempt.

Do you keep my videos?

Files move through a Worker + storage pipeline and aren’t turned into any kind of public gallery or browseable archive. We’re here to fix, not to collect.
