How to trim videos online
Whether you need to cut the beginning off a recording, extract a highlight from a long video, or trim silence from the end of a clip, this free video trimmer makes it easy. The visual timeline scrubber lets you drag start and end points to select exactly the portion you want to keep.
Unlike server-based tools, this trimmer processes everything in your browser using FFmpeg WebAssembly. Your video files are never uploaded to any server, ensuring complete privacy. The tool re-encodes the selected range for frame-accurate cuts, giving you precise start and end points without keyframe alignment issues.
The trimmer supports MP4, WebM, MOV, and AVI formats, and preserves the original format in the output. The first trim requires a one-time download of the video engine (~30 MB), after which subsequent trims start immediately. For precision adjustments, use the number inputs below the timeline to set exact times in seconds.
