Trim Video Online — Cut Clips Free, No Re-encoding

What is the Trim Video tool?

Almost every video has dead weight: the five seconds of fumbling before the action starts, the awkward outro, the long pause in the middle of a screen recording. This free tool cuts your video down to just the part you want to keep. You enter a start time and an end time, and the tool extracts exactly that segment.

The clever part is that it uses stream copying: instead of re-encoding the whole video (slow, and it degrades quality), it copies the original video and audio data straight through. That makes trimming extremely fast — a two-minute clip is done in seconds — and the quality is bit-for-bit identical to the original. Everything runs in your browser with FFmpeg, so your video never leaves your device.

How to use it (3 steps)

1. Upload your video. Drag an MP4, MOV, MKV or WebM onto the drop zone, or click to browse your device.
2. Set the segment to keep. Enter the start time and end time in m:ss (e.g. 0:45 and 2:10) or plain seconds. Everything between them is kept; the rest is dropped.
3. Trim and download. Click the button — the video engine loads once on the first click (~30 MB), then the trim finishes in seconds and the clip downloads automatically.

When you'll need it (use cases)

• Cutting intros and outros: remove the fumbling at the start and the "bye!" tail from phone recordings and screen captures.
• Clipping highlights: pull the best 20 seconds out of a long recording to share in a chat or post as a Story.
• Cleaning up recordings: trim the silence before a meeting recording starts so the file starts on the action.
• Fitting platform limits: shorten a clip to fit a 60-second status video or a message attachment without re-encoding the whole thing.
• Splitting off a segment: isolate one scene from a longer video to reuse in an edit or a GIF.

Tips for the best results

• Expect keyframe snapping. Because nothing is re-encoded, cuts snap to the nearest keyframe — the exact frame may shift by a fraction of a second. For social clips this is invisible; don't use this tool for frame-perfect editing.
• Give yourself a margin. If you need the action to start at a precise moment, set the start time a second earlier rather than later.
• Trim before you compress. Cut first, then shrink with the Compress Video tool — there's no point spending minutes encoding footage you'll throw away.
• Check the end time. If your end time is past the video's length, the tool keeps everything up to the end — no error, just the full tail.
• Same format out as in. MP4 stays MP4, WebM stays WebM, so playback compatibility is unchanged.
