How it works
Select a file from your device. It stays in your browser.
Move the trim controls, then choose an optional filter or output framing.
Use Fast Trim for eligible MP4/M4V files or create an exact re-encoded MP4.
With an MP4/M4V file, Normal filter, and Original framing, the editor copies video and audio streams instead of rendering every frame again. It is ideal for quick cuts, although the starting frame may move to a nearby keyframe.
Use our Video Converter & Compressor to create a smaller MP4 for email, messaging, and sharing. Choose a compression level, process it locally, then compare the finished file size before downloading.
