AtomWrap: MKV/WebM to MP4

Fast Video Conversion

Only for Mac

Free

Mac

Turn MKV files into Apple-friendly MP4/M4V without re-encoding video when possible. WebM files are converted for Apple playback. Drop in an MKV or WebM file and get a clean Apple-friendly video file for native playback on iPhone, iPad, Mac, Apple TV, and via AirPlay. AtomWrap is a native Mac app with an elegant Liquid Glass interface that feels right at home on macOS Tahoe. Drop a file and hit Wrap. Details are visible if you want them, hidden if you don't. For compatible MKV files, AtomWrap doesn't re-encode the video. It rewraps the original untouched video into a container Apple devices understand, so conversion takes seconds rather than hours and preserves the original quality. WebM files are converted for Apple playback. Audio is converted to AAC for compatibility, with stereo or surround options. Text subtitles are carried into the output so they can be turned on or off during playback. Features - Supports MKV and WebM input - Apple-friendly M4V output for iPhone, iPad, Mac, Apple TV, and via AirPlay - Compatible MKV video preserved without re-encoding when possible - WebM video converted for Apple playback - AAC audio with stereo or surround channel options - Text subtitles included as soft subtitles you can toggle during playback - Stream summary visible before conversion starts - All processing on your Mac - no uploads, no accounts, no tracking AtomWrap does one job deliberately: it makes MKV and WebM files easy to use with your Apple devices.
