FixMP4 repairs corrupted, truncated or unplayable MP4, MOV and M4A files, including iPhone Voice Memos, right in your browser. Files never leave your device. You get a free preview of your repaired file; a subscription ($9/mo or $29/yr) unlocks full export.
What it does: When a recording is interrupted by a dead battery, a crash, full storage or an app being closed, the video data is usually still there but the index (the "moov atom") that players need is missing or damaged. FixMP4 analyzes the file structure locally, scans the media data for H.264/HEVC video frames and AAC audio frames, and rebuilds a fresh, standard index so the file plays again in VLC, QuickTime, Windows Media Player, iMovie or Premiere.
Who it's for: anyone with a broken phone video, an interrupted iPhone Voice Memo, a cut-off GoPro, DJI or dashcam clip, a camera MP4/MOV, or a screen or meeting recording from OBS, Zoom or QuickTime that refuses to open.
Privacy: zero bytes of your video are uploaded. The whole repair runs in your browser, and large multi-gigabyte files are processed in slices.
Pricing and access: diagnosis and a free 15-second preview of your own repaired file are free. If the preview plays, a subscription of $9 per month or $29 per year unlocks full export with unlimited repairs, cancelable anytime.
Key features: in-browser repair with no installation, support for MP4, MOV and M4A, a reference-file mode for videos, audio-only repair for Voice Memos, and a try-before-you-buy preview.
