Video converter – Convert any video to MP4 or WebM

Often, yes. MOV and MKV usually hold H.264 or HEVC video that MP4 can store as it is, so FotoJock copies it without re-encoding: it takes seconds and the quality is identical. Otherwise the video is re-encoded at the quality you choose.

Yes. Old formats the browser cannot read itself are decoded by a small LGPL build of FFmpeg’s decoders that loads only when such a file shows up, and are then encoded to MP4 by your browser.

Yes: MOV and MP4 in H.264 or HEVC, portrait or landscape, with variable frame rate. Rotation is kept, sound stays in sync, and HDR videos are converted to normal colours when the output cannot hold HDR.

FotoJock uses H.265 (HEVC) when your device has a hardware HEVC encoder, as iPhones, Macs and many Android phones and Windows PCs do: the same quality in about a third less space. Elsewhere it uses H.264, which plays everywhere. AV1 is offered only where it is hardware accelerated. The settings show which encoder your device uses.

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.

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.

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.

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.

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.
