Trim, cut & crop
Cut a video to the part you want and crop the frame, right in your browser. Nothing is uploaded.
Files are processed in your browser and never uploaded.
How to use Trim, cut & crop
Add your file
Drop your video file onto the upload area, or tap the area to choose it from your device.
Set the options
Choose Engine, Start (s), End (s), Crop and Shape. Every setting is on screen before you add a file, so you can see what the tool will do before it runs.
Run it and save
Press Apply edits, Don →. The button stays disabled until there is something to work on, and each file shows its own progress and result. Press Download video, Don. Each finished file keeps a name based on the one you started with, so you can tell the versions apart.
What this tool does
Trim and cut video to a time range
Set a start and end time and the video is cut to that range, with Set to current filling in the time you are paused at.
Crop a region with a visual box
Drag a crop box over the preview to choose the region, free-form or locked to 1:1, 16:9, 9:16 or 4:3.
Hardware-accelerated fast engine with a compatible fallback
The quick engine uses your device's hardware encoder where it can, with a built-in fallback for the files it cannot handle.
MP4 or WebM output
Output as MP4 (H.264) or WebM (VP9), at balanced, better or best quality, with the audio kept, lowered or removed.
No upload, no sign-up
A video up to 1 GB is decoded and re-encoded in your browser, so nothing is uploaded and there is no sign-up.
Frequently asked questions
Are my videos uploaded anywhere?
No. The trimming, cutting and cropping all happen inside your browser on your device, and the video is never sent to a server.
Is there a size limit?
Yes, the limit is 1 GB per video and one video at a time. Everything runs on your device, so large or long videos use a lot of memory; files near that size are the most likely to slow down or crash the tab, especially on the compatible engine or on phones.
What are the two engines?
Quick mode edits with your browser's built-in recorder, needs no download, and works almost everywhere; it runs in real time, roughly as long as the kept part plays. ffmpeg mode downloads a built-in engine (about 31 MB) the first time and gives finer quality control. You can pick either one above; if one cannot run, switch to the other.
How do trim, cut and crop work together?
Trim and cut keep only the part between your start and end times. Crop keeps only the rectangle you draw on the video. You can use both together or just one of them, and the result is exported as a new video.
Will the quality change?
Editing re-encodes the video, so there is a small quality cost, set by the quality option. Cropping changes the picture on purpose by keeping only the area you select; trimming on its own mostly just shortens the clip.
Which formats can I use?
It reads most common video files and outputs either MP4 (H.264), which plays almost everywhere, or WebM (VP9). If your browser cannot make the format you picked, the tool switches to the one it can.
