Convert Video open in OneMacApp, with its settings in the inspector.

How it works

Three steps.Nothing to learn.

  1. 1

    Drop your videos

    MOV, MP4, M4V, MKV, WebM, AVI and MTS all work. Drop one file or a whole folder’s worth.

  2. 2

    Pick a format

    MP4 for almost everything, MOV for Apple apps and editors, or WebM for the web.

  3. 3

    Press Convert

    The converted copies are saved together in a dated OneMacApp folder in Downloads. The originals stay exactly as they were.

The details

Everything you’d want.Nothing you wouldn’t.

  • Opens the awkward ones

    MKV, AVI and camcorder MTS files that QuickTime refuses become ordinary videos you can play, share and edit.

  • Three useful targets

    MP4 and MOV are saved as H.264 with AAC audio. WebM uses VP9 video with Opus audio, the pairing browsers expect.

  • Good quality by default

    Video is re-encoded at a high quality setting, so the result looks like the source without you having to tune anything.

  • Stays on your Mac

    Conversion runs locally with FFmpeg. There is nothing to upload, no wait in a queue and no limit on file size.

FAQ

Questions,answered.

Drop the MKV into Convert Video, leave the format on MP4 and press Convert. The new MP4 plays in QuickTime, Photos, iMovie and on an iPhone.

Both hold the same H.264 video and AAC audio here. MP4 is the safer choice for sharing and the web. MOV is handy if an Apple app or editor you use prefers it.

WebM is made for websites. Pick it when you are putting a video on a page yourself and want an open format that browsers play natively.

The video is re-encoded, so it is not a bit-for-bit copy, but it uses a high quality setting and most people cannot tell the difference. If you also want a smaller file, use Compress Video.

Yes. Drop as many as you like. Every file gets the same format and they all land in the same folder.
