MP4tools is a macOS video utility for creating, converting, joining, splitting, and editing MP4 or M4V files for playback on Apple devices and other hardware.
What is MP4tools?
MP4tools is a native macOS video utility that helps users create and edit MP4 and M4V files from common video formats such as MKV, MP4, OGM, and AVI. Published by Emmgunn as part of the VIDEOtoolbox suite, it is aimed at people who want to prepare videos for playback on devices like iPhone, iPad, Apple TV, and other compatible players. The app can convert files into MP4, join clips together, split larger videos into smaller parts, and extract individual audio or video tracks from existing MP4 files. It also supports subtitle handling, including adding external subtitles or burning subtitles into video when needed. Presets and batch-style workflows make it practical for users who process multiple files with similar settings. For Mac users who need a focused desktop tool for MP4 container editing and conversion tasks, MP4tools fits into straightforward personal media workflows.

Safety overview
Status: Mostly safe
MP4tools is a standard desktop media utility for working with video files you choose to open. Access to your files is normal for its purpose, and removing it does not affect macOS itself, but you may lose saved presets, queues, or app-specific settings if you delete its support files. Use it with copies of important media when making edits such as splitting, joining, or subtitle changes so you can keep the original files untouched.
Recommendation: Keep MP4tools if you actively convert or edit MP4 and M4V files on your Mac. If you no longer use it, you can remove the app and its leftover support files to recover space, though doing so may remove saved presets and other app preferences.
