trim start and end
Keep the part that matters, drop the rest
Give it a start and an end and it returns what sits between them. Where the file allows it the cut is made without re-encoding, so the picture arrives untouched and the job takes seconds.

What happens when you drop a file in
The file stays put. Your browser opens it the same way an image viewer would. There is no transfer, which is why there is no upload bar to watch.
An encoder arrives once. The first job on this site pulls down a compiled build of FFmpeg, roughly 30 MB. It is kept afterwards, so every job after the first starts immediately.
Your own hardware does the job. The work happens in this tab, on your processor. A laptop from the last few years handles short clips in well under real time.
The result lands in Downloads. Assembled in memory and handed straight to your browser. Close the tab and every trace of it is gone.
Trimming beats compressing, almost always
File size tracks duration more directly than it tracks any quality setting. Reducing a three minute clip to the thirty seconds worth keeping removes five sixths of the data before compression is even considered.
That makes trimming the first move whenever something will not fit an upload limit. People reach for a compressor instead and pay for it in picture quality, when the frames they were about to throw away were the cheaper thing to lose.
Times can be written however you think about them: plain seconds, minutes and seconds like 1:30, or the full 0:01:30. The end time is counted from the beginning of the original file rather than from your start point.
Why a cut sometimes lands slightly off
On the fast path the cut snaps to the nearest keyframe, which can shift the start by a second or two. This is a property of how video compression stores frames rather than a shortcoming here — most frames simply do not contain enough information to begin from. If you need the cut exactly where you asked, the slower path is accurate to the individual frame.
Common questions
What time format should I use?
Seconds, minutes and seconds, or hours and minutes and seconds. All three are understood.
My clip starts a second early.
The fast path cuts at keyframes. When exact timing matters, the re-encoded path is frame accurate.
Does quality change?
Not on the fast path, where the video is copied. On the fallback the loss is invisible at the default setting.
Can I cut a section out of the middle?
No. This keeps one continuous stretch. Removing a middle section means two cuts and a join, which needs an editor.
