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 3GP files stop playing

3GP is the format older phones and some messaging apps used for video. It is built like MP4, with an index (the moov atom) that tells a player where the footage is.

A recording that stopped when the battery died or the memory filled, or a transfer that ended early, can leave that index missing. Players then refuse the file even though the footage is often still inside.

FileFix rebuilds the index from the footage that is present and only offers checkout when it produces a playable file. Footage that was never recorded cannot be recreated.
