Trimma
Trimma is a macOS video and audio trimming app for quickly cutting media, exporting clips, and preparing files without a full editing suite.
What is Trimma?
Trimma is a native macOS media editing app focused on fast video and audio trimming. It helps users cut unwanted sections, keep selected portions, and export finished clips without the overhead of a full nonlinear editor. The app supports precision cutting, multiple export presets, and passthrough export workflows that can preserve quality while avoiding unnecessary re-encoding when supported. It also includes audio waveform viewing for audio work and command-line tools for users who want to automate repetitive media-processing tasks. Common uses include preparing short clips for sharing, making rough first-pass edits, splitting one source file into multiple outputs, and converting media into practical delivery formats. Trimma is published by Karsten Kusche and is aimed at creators, editors, and other macOS users who need focused trimming and export tools.

Safety overview
Status: Mostly safe
Trimma is a legitimate media-processing app for macOS. Access to your files is normal for a video and audio trimming tool, since it needs permission to open source media and save exported results. If you use command-line features or process important originals, keep backups of source files before batch work so you can recover easily from unwanted edits or exports.
Recommendation: Keep Trimma if you actively edit or trim video or audio on your Mac. If you no longer use it, removing the app is usually fine, though you may also want to delete its support files and caches if you want to free additional space.
