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

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 WAV files stop opening

WAV is the format professional recorders, DAWs, and field recorders write when they want uncompressed sound. Most "corrupted WAV" problems are structural: the header that declares the sample rate, channel count, and data length got damaged or was never finalized — which is exactly what happens when a recorder loses power or an app crashes mid-take, so the file is left without a proper end.

When the header is wrong or the length was never written, a player refuses the file or reads it as noise — even though the raw audio samples are usually still there. FileFix reads the actual sample data, rebuilds a correct WAV header around it, and produces a file your player can open. You hear a free watermarked preview clip and see how much we recovered before paying.

This works for many header, length, and sample-rate problems. It can't recover audio that was never written to disk.

What we can and can't fix

We can usually fix

  • WAV files from field recorders, DAWs, and recorder apps that won't open, report a bad length, or play as noise.

We can't fix

  • Genuinely empty files, deleted files, or physically damaged storage. 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 preview before you pay.
