About QuickTime (MOV)
MOV is the QuickTime container format from Apple. MP4 was based on it, so the two share the same structure, but MOV is also used for editing codecs such as Apple ProRes.
iPhones and many cameras record MOV, and editors such as Final Cut Pro export it.
Outside Apple software, MOV files that use ProRes or other professional codecs often do not play without extra software.
Convert MOV to MKV online free, no account required — MKV is a flexible open container for video with any number of audio and subtitle tracks.

Why won't my MOV file play on Windows or Android? QuickTime containers often carry Apple-specific codecs such as ProRes, so converting to MP4 with H.264 makes the video play everywhere.
About Matroska (MKV)
Matroska (MKV) is an open container format that can hold almost any video and audio codec, any number of audio and subtitle tracks, chapters and attachments.
It is popular for films and series with several audio languages and subtitle tracks, and for archiving video.
Many phones, browsers and TVs do not play MKV files directly, even when they support the codecs inside.
Why convert video to MKV? When one file must carry several audio languages, subtitle tracks and chapters, no container holds them as flexibly.
What changes when you convert MOV to MKV
- The MOV is re-encoded into MKV at the default quality settings, so the result looks close to the original but is not bit-identical.
Settings you can change
Before you convert MOV to MKV, you can adjust: Video codec, Rate control, Quality (CRF), Video bitrate, Resolution, Width, Height, Scale fit, Frame rate, Encoder preset, Audio codec, Audio bitrate, Trim start, Trim duration, and Remove metadata.
Limits
Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted MKV file is kept for 2 hours, then deleted.
