FileFix

Repair a corrupted FLAC file.

A corrupted FLAC file can be rejected when its stream metadata or audio frames are truncated or inconsistent. Upload it for a repair attempt; FLAC is accepted for analysis, and you see the outcome before checkout and pay nothing if the current engine cannot rebuild it.

Drop a broken audio file here — the free preview shows what's recoverable before you pay.

Files up to 2 GB.

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

Your files auto-delete within 48 hours

No person looks at your file as part of repair

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. You can try another file.

FileFix can't fix that kind of file yet.

Right now we repair video, audio, and document files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, ZIP, and PDF). 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 FLAC files stop playing

A FLAC stream begins with metadata blocks that describe the audio and is followed by individually framed compressed audio. A cut-off transfer can leave an incomplete metadata block or frame, while altered frame bytes can make stored checksums disagree with the decoded data.

Players use the stream marker, block lengths, frame headers, and checksums to find and verify the audio. Damage to those structures can stop decoding even when other frames remain in the file.

FileFix accepts FLAC for analysis, but the current repair engine may decline a file it cannot honestly rebuild. The result is shown before checkout; genuinely empty, deleted, or DRM-protected files cannot be repaired.
