How it works
Trimming is the commonest video edit there is: cutting the dead air off the front of a screen recording, pulling one moment out of a long clip, getting a file under a length limit. It is also the edit where uploading is most painful, because video files are big and the upload is usually slower than the edit. This runs ffmpeg inside the page, so nothing is uploaded and nothing is waited on.
How the cut is made
The clip is re-encoded rather than copied, which means the cut lands exactly where you put the handle. Copying without re-encoding is faster, but it can only cut at keyframes — which is why some trimmers silently move your cut by a second or two. This one does not.
It uses your device, so long clips take time
There is no server doing the work, so the encode runs at whatever speed your machine manages. A short clip is quick. A long one, or a 4K one, can take several minutes and will make a laptop fan audible. That is the honest trade for not uploading it.
What you get back
An MP4 with H.264 video and AAC audio — the combination that plays on essentially everything, from phones to browsers to TVs. The original file is untouched.
Size limits
Very large files cannot be handled, because the whole video has to fit in the browser's memory alongside the encoder. Around 250 MB is comfortable on most machines; beyond that you will be warned before anything is attempted.
Trim a video — questions
Is my video uploaded to a server?
No. The trim runs inside your browser using ffmpeg compiled to WebAssembly. The file never leaves your device.
Why is it slower than other online trimmers?
Because your own device is doing the encoding rather than a server farm. The upside is that nothing is uploaded and there is no queue.
Is the cut exactly where I put it?
Yes. The clip is re-encoded so the cut is frame-accurate, rather than being nudged to the nearest keyframe.
Is there a watermark or a length limit?
No watermark and no imposed length limit. The practical limit is your device's memory, and you are warned in advance if a file is too big.
