Choose start and end times directly in your browser. Keep the original streams with fast copy or re-encode precisely to a broadly compatible MP4.
Fast copy or precise encoding
Fast mode avoids re-encoding when possible. Precise mode creates H.264 video with optional AAC audio for accurate cuts and broad compatibility.
Local browser processing
Your video is never uploaded. ffmpeg.wasm trims it in the browser and the finished MP4 downloads directly to your device.
Video trimming FAQ
Do I need to upload my video?
No. Reading, trimming, and export happen in the current browser, so the media content is not sent to a server.
What is the difference between fast and precise trimming?
Fast trimming copies the original streams, which is usually quicker and avoids extra quality loss, but cuts can align to nearby keyframes. Precise trimming re-encodes for more accurate endpoints.
Why does fast mode sometimes fall back automatically?
Some source containers or codecs cannot be copied directly into MP4. When stream copy fails, the tool retries with precise re-encoding to produce a usable result.
Can I remove the audio?
Yes. Enable audio removal to export a silent MP4 for demonstrations, background footage, or later voice-over work.
