How do I cut a video online with Video Cutter Online?

Updated

Video Cutter Online (video-cutter-js.com) is a browser-based tool that cuts, converts, rotates, mirrors, compresses, resizes, and crops video. You open or drag a supported video file into the page, set start and end points, choose an output format and encoding options, then run the cut and save the result. Because it runs on HTML5 and JavaScript in your browser, the site states your video files do not need to be uploaded to a server for processing — which is the main reason to pick it over tools that require an upload.

Supported input formats

The tool lists these input formats: MP4, WEBM, MOV, FLV, 3GP, M4V, MPG, MPEG, MKV, AVI, WMV, MV, DV, ASF, 3G2.

If your file is outside this list, convert it first or use a different tool.

Step-by-step: cut a video

  1. Open the file. Click the file field ("Choose file...") or drag your video onto the drop area. The page shows a video preview once the file loads. Nothing is uploaded, so the file stays on your machine.
  2. Set the cut range. Use the Start and End fields to mark where the clip should begin and end. Check the preview to confirm the points land where you want.
  3. Choose the output format. Under the cut settings, pick from MP4, AVI, MPG, MOV, FLV, 3GP, WEBM, MKV, WMV, GIF, or the Apple Video / Android Video presets.
  4. Adjust encoding if needed. The cut panel exposes a video encoder (H.264 or MPEG-4), an audio encoder (MP3 or AAC), audio quality (48k–256k), audio sample rate (8000–48000), audio channel (mono/stereo), a "Remove audio" toggle, and a preset list covering 1080p/720p/480p/360p/260p/DVD/TV/Mobile at 25p, 30p, or 60p. There are also video bitrate, resolution, and fps fields.
  5. Run the cut. Start the operation. The result is produced in the browser.
  6. Save the file. Download the output locally.

What else the same page does

The tool groups its functions into tabs, and the cut tab is only one of them:

Function What you set
Cut Start/End points, output format, encoders, quality, preset
Convert Output format and encoding settings
Rotate 90° clockwise or counterclockwise
Mirror Horizontal or vertical mirroring
Compress Output file size target (0–10M shown), resolution, fps
Resize Resolution and fps
Crop Starting X/Y, width, height

If your goal is only to trim a clip, stay in the cut tab — the other tabs are separate operations.

Practical notes

  • Do the cut before heavy compression. Trimming first means the compressor only processes the part you keep.
  • GIF output is available in the format list, which is useful for short clips but produces much larger files than video formats for the same duration.
  • Audio-only trimming: set "Remove audio" to yes if you want a silent clip, or pick a lower audio quality/sample rate to shrink the file.
  • Presets vs. manual settings: the preset list (HD 1080p, HD 720p, 480p, 360p, 260p, DVD, TV, Mobile at 25p/30p/60p) is the quick path; the bitrate/resolution/fps fields are for when you need a specific target.
  • Language support: the interface is available in many languages, including English, Spanish, French, German, Chinese (Simplified and Traditional), Japanese, Korean, Arabic, Hindi, and others.

Common snags

  • File won't load: confirm the extension is in the supported list above.
  • Cut points feel off: re-check the preview after entering Start/End — the fields are numeric and a misplaced value shifts the whole clip.
  • Output looks worse than the source: a low preset or bitrate is the usual cause; raise the resolution/bitrate or pick a higher preset.
  • Large files: since processing happens in the browser, very long or high-resolution files depend on your machine's memory and CPU rather than a server.
