Video Repair Online: Fix Corrupted Videos

Repair corrupted MP4, MOV and AVI videos in your browser. Your files stay on your device: no upload, no account.

Video Repair Online fixes MP4, MOV and AVI videos that will not play, show 0:00 as their length, or cannot be skipped through. It rebuilds the missing index of the file so the footage that is still inside it becomes playable again. HOW IT WORKS - MP4 and MOV: choose the corrupted video and a healthy video from the same camera or app. The extension copies the codec settings from the healthy one, finds every frame in the damaged file and writes a new index. - AVI: choose the corrupted file. In most cases no reference video is needed. - Save the repaired video as a new file. Your original is never changed. PRIVATE BY DESIGN - Everything runs on your own device, inside the browser. Your videos are never uploaded. - The extension asks for no browser permissions and collects no data. - Works offline. WHAT IT SUPPORTS - MP4 and MOV with H.264 or H.265 video and AAC audio - AVI with common video and audio codecs - Large files: they are read in small pieces, so the extension does not set a size limit GOOD TO KNOW - MP4 and MOV repair needs a healthy reference video recorded on the same device with the same settings. - In MP4 and MOV files, sound is kept only when it is AAC-LC. - The order of frames in videos that use B-frames is not rebuilt. - MKV, WMV and MTS files are not supported. - Footage that was never written to the file cannot be recovered. Always keep your original. Guides, FAQ and the web version: https://videorepaironline.com/
