About MKV
Matroska started in 2002 as a free, open container that can hold any codec. MKV files are common for movies and shows, and OBS and many other apps can record to it.
One MKV can hold several sound tracks, subtitles and chapters. The video is usually H.264, HEVC, VP9 or AV1, and the sound AAC, Opus, FLAC or the Dolby Digital and DTS tracks of films.
Chrome and Firefox play many MKV files by themselves since version 145. For the rest, Filepeek reads the file itself, lets the browser decode the video it can, and decodes Dolby Digital, DTS and older codecs on its own.

Questions
Why won't MKV files play in my browser?
Few browsers play MKV by themselves, and Chrome plays it silent when it can't decode the sound, such as Dolby Digital. Filepeek reads the file itself and decodes that sound and older codecs, so MKV plays here with nothing to install.
Does it play Dolby Digital and DTS sound?
Yes. Filepeek decodes AC-3, E-AC-3 and DTS inside your browser, which most browsers can't do on their own.
Can I turn an MKV into an MP4?
Yes. Open it, choose Export, then Save as MP4. Keep it all, or drag the handles on the frame strip to save only a part.
Is my video uploaded?
No. The file plays inside your browser and never leaves your device.
