How it works

How to use it

  1. Choose your videos, a whole folder, or drop them on the page.
  2. Pick the settings (the defaults suit most phone videos) and watch the progress, file by file.
  3. Compare before and after in the player, then save each file, a ZIP, or straight into a folder.

Questions

Which audio formats can I save?

MP3 (with the LAME encoder), M4A with AAC (copied without re-encoding when the video already has AAC sound), WAV (uncompressed) and Opus in OGG. Only extract audio from videos you have the rights to.

How big can the videos be?

Several gigabytes. The video is read in pieces and big results are written to your browser’s private storage on disk instead of memory, so long recordings work on computers and, more slowly, on phones.

Can I convert many videos at once?

Yes. Drop a whole folder or choose as many files as you like. They are converted one or two at a time, with a progress bar and time left for each, and you can pause, stop, retry, and save everything as a ZIP or straight into a folder.

Are my videos uploaded anywhere?

No. Your videos are read, converted and saved by your own browser, using your device’s video hardware where it has it. Nothing is sent to a server, so even private or very large videos stay on your phone or computer.

Which browsers work?

Recent Chrome, Edge, Safari (16.4 or newer, also on iPhone and iPad), Firefox (130 or newer) and Android browsers, all of which encode video with WebCodecs, usually in hardware. Which codecs are available depends on the browser and the device.

Is it really free?

Yes, with no account, no watermark and no limit on the number of files. FotoJock is made by Foto Jocković, a photo shop in Belgrade.
