What Video Cutter does
Cut a selected time range from a short video privately on your device or with the faster compatibility server. The tool keeps the operation focused and creates a separate result so the original remains available for comparison.
Video Cutter offers a private browser mode and a native server mode. The interface explains the speed, compatibility, memory, and upload tradeoffs before processing starts.
How to use Video Cutter
For a predictable Video Cutter result, keep the source available, test the smallest useful example first, and confirm the downloaded or displayed output independently.
- Select a short representative video, animation, or capture source and confirm the displayed duration and dimensions.
- Choose the required timeline range, frame, layout, audio, or output settings for the destination.
- Create the result and watch the complete preview, including transitions and the first-to-last loop boundary when relevant.
- Test the downloaded file in the target browser, player, editor, or publishing service before deleting the source.
Where Video Cutter fits
Use this media workflow to prepare a short clip, recording, or animation for a known player, platform, presentation, or editing step. Decide the required dimensions, duration, frame behavior, audio state, and output format before processing so every setting has a clear purpose.
What to check
Review frames and audio immediately around the selected timestamps. Compressed video may align cuts to nearby keyframes during re-encoding.
Review the whole timeline for correct framing, orientation, timing, animation loops, audio sync, captions, and legible overlays. A short representative clip is useful when choosing compression settings.
Privacy and limitations
Private mode loads a self-hosted FFmpeg WebAssembly engine after you request it and processes the video on this device without uploading the file. Server mode uploads only the selected video for a bounded native FFmpeg request and uses a temporary workspace with best-effort cleanup.
Private mode requires WebAssembly, a web worker, sufficient device memory, and a one-time engine download; it can take substantially longer than native server processing, particularly on phones. Server mode is usually faster and more compatible but uploads the selected file temporarily. Exact cuts re-encode the clip and can change quality, metadata, and file size.
