How it works
Set the range
Drag the timeline handles or enter precise start and end times, then preview the selected section.
Trim and download
The selected range is accurately re-encoded as a broadly playable MP4.
Accurate trimming without a full editor
The compact editor timeline keeps visual handles and precise time fields synchronized. Start and end values are clamped before processing, so negative, reversed, out-of-range, and unusably short selections cannot become an invalid job.
Accurate mode re-encodes the selected range to H.264/AAC. That is slower than stream copy, but it avoids cuts unexpectedly snapping to nearby keyframes.
Frequently asked questions
How do I cut part of a video?
Select a video, wait for its duration to load, set the start and end in seconds, then choose Trim video.
Does trimming reduce quality?
The selected section is re-encoded for accurate cut points, so a small generational quality change is possible.
Can I trim MOV and MP4 videos?
Yes, the tool accepts MOV, MP4, and WebM containers when their internal codecs are supported by FFmpeg.wasm.
Is processing local?
Yes. The video is read, trimmed, previewed, and downloaded on your device without a media upload.
