Files up to 2 GB.

Free preview — pay only if you download ($8)

Your files auto-delete — delete them sooner anytime

No person looks at your file as part of repair

Repair your file

Choose a supported file to see what can be repaired before checkout.

You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.

Try another file

Good news — your file isn't damaged. No charge.

There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.

We couldn't recover this one.

The file is too damaged to rebuild, so there is nothing to preview and no charge.

Unrepaired files are kept encrypted for up to 30 days, then deleted.

FileFix can't fix that kind of file yet.

Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

We store just your email and the file type — never the file itself. One message, when it's ready. No spam.

Why MP3 files get corrupted

Voice recorders and audio editing apps write MP3 files, which are also used for music and podcasts. Most "corrupted MP3" problems are not damage to the sound itself. They're damage to the structure of the file: the frame headers and metadata a player reads to find and decode the audio. That structure can be broken or missing after an interrupted download, a failed transfer, an app crash, or storage pulled too soon.

FileFix accepts MP3 files and analyzes what is recoverable, but the current repair engine does not yet rebuild every MP3 failure mode. If it cannot produce a playable result, you see that before checkout and pay nothing.

What no repair can do is invent sound that was never recorded — a genuinely empty file has nothing to rebuild.

What we can and can't fix

What happens when you upload

  • MP3 files are accepted for analysis, with the result shown before checkout.

We can't fix

  • The current engine may decline an MP3 it cannot honestly rebuild; genuinely empty, deleted, and DRM-protected files also cannot be repaired. More →

How it works

  1. Upload Drop a supported audio file in. It uploads over an encrypted connection. The repair runs automatically — no person listens to your file.
  2. Free Watermarked Preview You hear a free watermarked preview clip and see exactly how much we recovered.
  3. Pay & Download If it's right, you pay $8 once and download a clean, full-quality audio file.

About half of real-world corrupted files repair fully; you always preview first.
