What does this video trim tool do?
This tool lets you trim a video directly in your browser - drop a file, drag the two handles under the preview to choose exactly where it should start and end, then export. There's no account, no upload, and no waiting on a server: your file is read, cut, and downloaded without ever leaving your device.
How do you trim a video online? Drop your file onto the tool, drag the start and end handles under the preview to select the part you want to keep, then click Trim Video. The clip is cut and downloaded straight to your device at the exact same quality as the original - nothing is uploaded.
Fast mode vs. Original quality mode
A basic trim tool can cut a video without re-encoding it at all, but that only works if the cut lands exactly on an existing keyframe - many videos, especially screen recordings and web downloads, only have keyframes every few seconds (sometimes just one, at the very start), so the beginning of the clip would silently fail to trim and jump back to frame 0 no matter where you dragged the handle.
To make trimming a video actually land where you drag it, this tool re-encodes the video rather than doing a raw copy. Fast mode (the default) does this using your device's own hardware video engine at the highest quality setting available - there's no visible or measurable difference from the source, and it's ready in seconds. Original quality mode re-encodes at the same bitrate as your source file instead, so the result matches its quality and file size closely, at the cost of taking much longer since it runs in software. The audio track is copied directly in either mode since audio frames are only tens of milliseconds long, so there's nothing to lose there. Fast mode currently supports MP4, MOV, WebM, MKV, and TS files - other formats automatically use Original quality mode.

Common uses for trimming video
Cutting dead air
Remove the pause before you start talking or the silence at the end of a screen recording, without re-exporting the whole thing.
Clipping a highlight
Pull a single moment out of a longer recording to share on its own, whether that's a gaming clip, a meeting excerpt, or a phone video.
Preparing for a compressor
Cut a long source video down to just the section you need first, then run it through a compressor for a much smaller final file.
Removing intros or outros
Strip an unwanted intro, watermark segment, or outro from a downloaded or recorded video before reusing it elsewhere.
Frequently asked questions
Can I trim an MP4 video with this tool?
Yes. MP4 is the most common format this tool sees, along with WebM, MOV, AVI, and MKV. The trimmed file keeps the same container and codec as your original.
Is there a file size limit?
There's no hard limit, but very large files need enough free memory on your device since everything is processed locally rather than on a server.
Is my video uploaded anywhere?
No. The entire trim happens in your browser using a local video engine. Your file never leaves your device.
Why does it download something on first use?
The local video engine that powers the trim is about 30 MB. It downloads once and is cached by your browser, so future visits load instantly.
Can I trim multiple videos in a row?
Yes. After downloading one trimmed clip, drop in another file to start a new trim - the video engine stays loaded for the rest of your session.
