About Trim & Cut
Cuts one or more segments out of a video, each with its own start and end point, without needing a full video editor. Add as many segments as you like, download each one individually, or merge them all into a single combined clip. Runs in your browser: the video never leaves your device, but the first use downloads a processing engine from a public CDN.
Upload your video, add a segment (start and end time as seconds, m:ss or h:mm:ss) for each cut you want, and process them. Each segment downloads on its own, or use Merge All to combine every segment into one file in the order they're listed.
"Exact" (the default) cuts at precisely the times you type and always produces a playable clip; it re-encodes, so it takes longer. "Fast" copies the video without re-encoding (identical quality, seconds) but can only start on a key frame, so the clip may begin up to a few seconds early; if that would leave no picture, the tool switches to an exact cut for that segment and tells you. Some phone-recorded videos (particularly .mov files) use a codec this tool can't read — if processing fails right away, try re-exporting the video from your phone's own share options first.
Watch: Trim & Cut in Action
- Will trimming reduce my video's quality?
- Individual segment trims use a fast method that doesn't re-encode the video, keeping quality identical to the original. The trade-off is that it can only cut precisely at the video's existing keyframes, so a segment may start up to a second or two off from the exact time you typed.
- Can I combine multiple trimmed segments into one file?
- Yes — use Merge All to combine every segment you've added into a single file, in the order they're listed. Merging re-encodes the combined result, which takes longer than trimming alone.
- What is the difference between Exact and Fast?
- Exact re-encodes the clip to MP4 (H.264 video, AAC audio at 128 kbit/s) so it starts at your typed time, but takes longer. Fast copies the streams without re-encoding, so it is quick and lossless, yet it starts at the nearest earlier key frame.
- How do I type times?
- Plain seconds such as 65.5, minutes and seconds such as 1:05.5, or hours:minutes:seconds. End must be later than start, and start must fall inside the video's length, otherwise a message appears and nothing is processed.
- Can I put several pieces into one file?
- Yes. Add a segment for each piece, press Trim All Segments, then press Merge All & Download. Pieces are joined in the order listed and saved as one MP4. Merging needs at least two finished segments.
- Why does it say it is downloading a processing engine?
- The cutting is done by FFmpeg running inside your browser, and that engine, about 25 MB, is fetched from a public CDN the first time you trim. It is the engine that is downloaded; your video is never sent anywhere.
- What format do the downloaded clips have?
- Exact cuts and merged files are MP4. A Fast cut keeps the original file extension, unless that segment fell back to an Exact cut, in which case it is MP4. The toast message after trimming states which applied.
How to use Trim & Cut
Drop a video onto the page and it appears in a player with one segment already spanning its full length. Choose a Cut type, Exact (recommended) or Fast. Type each Start and End as seconds (65.5), minutes:seconds (1:05.5) or hours:minutes:seconds, or scrub the player and press Set start to player time or Set end to player time.
Press Add Segment for every extra piece you want; the bar above the segments shades the selected parts of the video. Press Trim All Segments and watch the progress bar, which has a Stop button. Each finished piece gets its own Download Segment button. Once two or more are ready, Merge All & Download joins them in list order into a single MP4.
When to use it
Handy for cutting dead air from the front of a screen recording, pulling one answer out of a long meeting recording, saving a few highlights from a family video to send by message, or removing a mistake from the middle by keeping the segments on either side and merging them. No editor timeline is involved.
When not to use it
This is a cutter, not an editor. It adds no titles, transitions, music or color changes, and it cannot reframe a video or shrink it to a target file size; use a dedicated video editor for that. Very long or high-resolution recordings can also outgrow your browser's memory, in which case the cut is better done on a desktop computer.
Tips for best results
Choose Fast only when the original container must stay as it is and a slightly early start is acceptable; it copies the stream, so quality is identical and it finishes in moments. When the start must land on the time you typed, use Exact. It re-encodes with the picture bitrate capped near the source's average, which keeps a short clip from growing. Editing any time box clears that segment's result, so run it again before downloading.
Limitations
A Fast cut can only begin on a key frame, so the clip may start earlier than the time you typed, sometimes by a few seconds. If the copied piece has no usable picture, that segment is redone as an Exact cut and a message tells you. Merging uses the trimmed pieces, and clips that differ in size or frame rate are converted to match. Some phone .mov files use a codec the engine cannot read.
Privacy
Your video is read into your browser's memory and cut there by FFmpeg compiled to WebAssembly, so the footage is never uploaded. The one thing downloaded is the FFmpeg engine itself, about 25 MB from the jsDelivr CDN when you first press Trim All Segments, which is why a restrictive network can block it. Finished clips exist only on your device until you save them.
