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

Choose a supported file to see what can be repaired before checkout.
Simulated checkout — no payment is processed.
Optional — we'll email your private download link.
You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.
Try another fileGood 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.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
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.

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.

FLAC players rely on the stream marker, metadata-block lengths, frame headers, and checksums. A truncated or altered block can stop decoding even when other frames remain in the file.

No. It means the current engine did not produce a result it could offer. Keep the original file unchanged so it remains available for another recovery method.
A one-time $8 — and only if the repair works. Seeing what was recovered is free, and checkout is only offered when the engine produces a validated repaired file.
