Cách hoạt động

Trimming a video usually means an upload, a queue, and a watermark. This trimmer runs the real FFmpeg engine in your browser, and its fast mode copies the original streams so the cut is instant and lossless.

  1. 1
    FFmpeg.wasm loads once
    The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is cached by your browser afterwards.
  2. 2
    You set the start and end points
    Drag the handles to scrub the preview, or play the video and snap a handle to the current frame. The file stays in your browser the whole time.
  3. 3
    FFmpeg cuts the clip
    Fast mode uses stream copy (-c copy) — no re-encoding, so it finishes almost instantly with zero quality loss but snaps to a keyframe. Precise mode re-encodes for a frame-exact cut.
  4. 4
    The trimmed clip is offered for download
    The result is handed back as a downloadable blob and previewed in-page so you can confirm the cut.

Your footage never leaves your device — no upload, no queue, no watermark, and no file-size limit. Ideal for trimming private recordings, sensitive footage, or large files that conversion sites would reject.
