Keep the good part, cut the rest.
Drop in a video, set the start and end of the clip you want, and download the trimmed result. It all runs in your browser with ffmpeg.wasm — no upload, no watermark.
Add a video
Drop in an MP4, WebM or MOV — it's processed on your device, never uploaded.
Set the clip
Drag the start and end points to the section you want to keep.
Trim & download
The engine cuts your clip in the browser and you download the MP4.
Is my video uploaded?
No. Trimming runs in your browser with ffmpeg.wasm — your video never leaves your device, which keeps it private and avoids upload waits.
The first trim is slow — why?
The video engine (ffmpeg.wasm, ~30 MB) is downloaded to your browser the first time. After that it's cached and much faster.
Which formats work?
Most common formats your browser can play — MP4, WebM and MOV. The output is an MP4.
Is there a length or size limit?
No artificial limit, but very large videos take longer since everything is processed locally in your browser's memory.
Is it free?
Yes — completely free, no sign-up and no watermark.
