Simple, precise video cutting
Fast, lossless mode
The clip is copied without re-encoding: it's instant and the original quality stays intact.
Precise mode
Re-encodes the section to cut exactly, down to the fraction of a second.
On-the-fly adjustment
Play the video and set the start or end at the right moment with a single click.
Confidential
Cutting happens on your device: your personal videos are never uploaded.
Trim a video with no software
Remove an overly long intro, keep the best moment of a match, or extract a section from a meeting: cutting a video shouldn't require editing software. Upload your video, choose the start and end, and download the clip.
Fast or precise: which mode to choose?
Fast mode copies the frames as-is, with no re-encoding: the clip is ready in seconds and keeps the exact original quality, but the cut snaps to the nearest keyframe (about one second, roughly). Precise mode re-encodes the section into MP4 to cut exactly where you asked; it's slower, with quality very close to the original.
Ideal for social media
Trim a short clip before posting it as a story, a Reel, or on TikTok, or to send it as a message. To turn it into an animation, use our “Video to GIF” tool.
Frequently Asked Questions
Does cutting a video reduce quality?
In fast mode, no: frames are copied without re-encoding. In precise mode, the video is re-encoded with quality very close to the original.
Why isn't the cut exact in fast mode?
Without re-encoding, a video can only start on a “keyframe”, generally every one to two seconds. Use precise mode to cut exactly.
What formats are accepted?
MP4, MOV (iPhone), MKV, WebM, AVI, and most common formats.
Is my video sent to a server?
No, everything happens in your browser thanks to FFmpeg. Only the conversion engine is downloaded.
