Video trimmer

Cut unwanted footage from the beginning or end of a clip. Set the exact start and end in seconds, preview the selection, then export only that range.

Video output is re-encoded WebM, up to 1920 px on the longest edge. Frame output is PNG, up to 3840 px. Input codecs depend on your browser. Video export uses real-time recording and is not lossless.

Compare the source with the actual export

We edited a VidLoop-generated product clip in this browser tool and exported the result. Click “Try demo video” to load the same source and test your own settings.

A two-second selection keeps the frame and supported source audio.

How to use video trimmer

  1. Choose a video and check its duration.
  2. Set a start time and a later end time; preview the range.
  3. Export the selection and play the downloaded clip to review its boundaries.

Cut a time range without changing the composition

Trimming removes time, not pixels. Keep the original frame while shortening a pause, removing a false start or preparing one AI-generated shot for an edit. This browser tool re-encodes the range; it is not a lossless keyframe cutter. The final edge can vary by one recording frame.

Video trimmer: choose the part worth keeping

Use the video trimmer when the frame already looks right and the problem is timing. A pause before the subject moves, an accidental ending or a long lead-in can distract from a short product shot. Set the first useful moment as Start and the last useful moment as End. The preview uses that range; exporting creates a new WebM rather than changing your original file. If you need to remove something from the side of the image, use Crop video instead.

Check the first and last frames of your trimmed video

For the demonstration clip, try Start 1 and End 3. The requested selection is two seconds. Play the exported result and inspect both edges: real-time recording and browser scheduling can add a small timing difference. The video trimmer retains the aspect ratio, but frames larger than the output limit are scaled down. Keep the source file if you may need another edit; re-encoding an already edited download introduces another compression pass.

When this video trimmer is a good fit

Use it for a short AI-generated shot, a product demonstration or a brief social clip. Work with one source clip and one contiguous range. This video trimmer does not join separate clips, remove an interior section, create subtitles or provide a multi-track timeline. Those tasks need an editor with that specific capability. A range longer than sixty source seconds is refused; shorten the selection before export.

Limits to check before export

  • MP4, WebM and MOV support depends on the codecs your browser can decode. A filename extension alone does not guarantee support.
  • Choose files up to 512 MB. Video exports process up to 60 source seconds at a time, in real time. Keep the tab visible and cancel if needed.
  • The output is WebM for edited video and PNG for a frame. This editor does not promise MP4 output, lossless editing or new AI-generated details.
  • Audio uses the browser audio graph; a source without sound may receive a silent audio track. Review the exported file before sharing.

Video trimmer FAQ

Does trimming reduce the video resolution?

The trimmer keeps the frame proportions. Exports are capped at 1920 pixels on the longest edge to keep browser memory bounded. Audio is retained through the browser audio graph when the source contains a supported audio track.

Is my video uploaded?

No. This editor reads the file inside your browser tab. The file, frames and typed text are not sent to Vidloop. The website has ordinary privacy-respecting page analytics.

What can I download?

A re-encoded WebM video. Choose up to 60 source seconds per export. Video output is capped at 1920 pixels on the longest edge; unsupported browsers show an error.
