About Trim Video
Cut a clip down to the part that matters — the useful minute of a long screen recording, the take without the false start. The trim happens in your browser, which is the point when the footage is something you would rather not upload to a stranger’s server. Trimming is free, and the clip is cut inside this page, so a private recording is never uploaded and nothing comes back watermarked. No sign up either.
How to use Trim Video
- Open the videoCommon formats your browser can play will load. Nothing is uploaded; the file is read from disk into the page.
- Set the start and endScrub to each point and mark it. The preview plays just the selection.
- ExportThe trimmed clip is saved to your device as a new file, leaving the original as it was.
Why the trimmed clip is re-encoded
Compressed video stores occasional complete frames and describes everything between them as changes from the last one. Copying only from the nearest complete frame would make the clip start early, so the section you marked is re-encoded instead: it takes longer than a copy-only cut, and the clip begins where you put the start.
Formats and what the trimmed file contains
MP4, MOV, M4V and WebM videos can be trimmed, and the clip keeps the format it came in. MP4, MOV and M4V are encoded as H.264 at quality setting CRF 20 with AAC audio at 128 kbit/s; WebM uses VP8 at CRF 20 with Opus audio. The cut starts and ends exactly where you set it rather than at the nearest keyframe, the shortest clip is a tenth of a second, and the frames carry no watermark or logo. Metadata such as the recording location is removed from the clip.
What it does not do
- A long recording can exhaust what the tab is allowed to hold, so something that works on a desktop may not on a handset.
- Because the clip is re-encoded, a trim takes longer than a copy-only cut and the file size can differ a little from the original rate.
- A dedicated editor will do this faster. What you get in exchange is that the footage never goes anywhere.
- Videos can be up to 200 MB, 60 minutes long and 4K (3,840 by 2,160 pixels).
Trim Video: questions people ask
- Is my video uploaded?
- No. The file is read and processed in the page, which you can confirm by watching the network panel while the trim runs — the bytes never appear in a request.
- Why did a large video fail?
- Almost always memory. A browser tab has a bounded amount and video decoding uses a lot of it. Closing other tabs or using a desktop browser usually gets it through.
- Can I trim a video on Windows or Mac without installing an app?
- Yes. The trimmer runs in a web page, so any up-to-date desktop browser can cut MP4, MOV, M4V or WebM files of up to 200 MB, 60 minutes and 4K. The trimmed clip is saved in the same format as the source.
- Will the trimmed video have a watermark?
- No. Nothing is added to the picture or the sound. No paid tier exists to remove a watermark either, because none is put there in the first place.
- Can I trim a video without losing quality?
- Almost. Because the clip is re-encoded so it starts exactly where you mark it, it is not a bit-for-bit copy, but it is encoded at CRF 20, a high-quality setting where the difference is very hard to see. The original file is never changed.
