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, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, 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 AVI files stop playing

AVI is still written by dashcams, older cameras, security systems and capture tools. The frames sit in a movi list, and an idx1 index at the end tells players where each frame is.

A recording that stopped without closing the file, or a copy that ended early, leaves the index missing or pointing past the end. Players then refuse the file, show the wrong length or cannot seek.

FileFix reads the frames that are present and rebuilds the index around them, and only offers checkout when it produces a playable file. Footage that never reached the file cannot be recreated.
