MP4tools+ 1.0.1
A native macOS app for fast, mostly-lossless video processing (MKV/MP4/WEBM/AVI → MP4), built on FFmpeg. Signed with an Apple Developer ID and notarized by Apple. Requires macOS 14 (Sonoma) or later, Apple Silicon.
New in 1.0.1
- Name audio & subtitle tracks — give any audio or subtitle track a custom name that's written into the output (so players show "English", "Director Commentary", etc.).
- Multiple external subtitles — attach several
.srt/.ass/.ssa/.vttfiles at once; each appears in the Subtitles list with its own include toggle and editable name. - Stability: fixed a release-build crash when dropping a file into the preview.
Which download should I get?
Two editions are attached — the only difference is what the in-app preview window can play back. Conversion, splitting, joining, extracting and aspect-ratio adjustment are identical in both.
| Download | In-app preview plays | Size |
|---|---|---|
MP4toolsPlus-1.0.1.dmg — Standard |
MP4 / MOV (native macOS playback) | small |
MP4toolsPlus-1.0.1-vlc.dmg — VLC edition |
MP4, MKV, AVI, WEBM and more (bundles VLCKit) | large (~150–250 MB) |
Pick Standard for the smallest download; pick VLC if you want to preview MKV/AVI/WEBM before converting. You don't need the VLC edition just to convert those formats.
