Video Trimmer
Cut a video down to the part that matters — losslessly, in seconds, right in your browser.
No installs, no upload, 100% free.
Trim a video in three steps
A free video cutter that runs entirely in your browser. Drop a file, mark the cut, download the clip.
- Step 1
Upload your video
Drag a video into the upload area, or click to browse. MP4, MOV, MKV, and WebM all work — the player shows it immediately.
- Step 2
Mark start and end
Drag the sliders or type exact times, then hit Preview selection to watch exactly the clip you're keeping before you cut.
- Step 3
Trim and download
The cut copies the video stream instead of re-encoding it — a gigabyte trims in seconds with zero quality loss, and nothing is uploaded.
What people clip
Most videos are one good moment with too much around it.
Social clips
Cut the highlight out of a long recording for Reels, Shorts, or a chat — full quality, no watermark.
Screen recordings
Drop the setup fumbling at the start and the dead air at the end of a demo or bug repro.
Phone videos
Trim a two-minute clip down to the ten seconds worth sharing — before it eats someone's inbox.
Lossless & instant
No re-encoding means no quality loss and no waiting — the cut is a stream copy, done in seconds even for big files.
Lecture & meeting moments
Keep the demo, the answer, the decision — cut a recording down to the fragment people will actually watch.
Need the words?
If it's the content you're after, SlayScribe transcribes the whole video to text — often faster than scrubbing.
Why the cut is lossless
This trimmer never decodes your video: it copies the compressed stream between your start and end marks straight into a new file. That's why it finishes in seconds and the quality is untouched. The one trade-off: cuts align to keyframes, so the start can shift back by a moment on some videos. Need a frame-exact cut? That requires re-encoding — a heavier tool we're building next.
Frequently asked questions
Is the video trimmer free?
Yes — the video trimmer needs no account, adds no watermarks, and sets no limit on how many clips you cut.
Is there any quality loss?
None. The video and audio streams are copied byte-for-byte — only the parts outside your selection are dropped.
Why did my clip start slightly before my mark?
Lossless cutting aligns the clip to keyframes. On videos with sparse keyframes the start can shift back by a second or two — trim a little tighter to compensate.
Which video formats can I trim?
MP4, MOV, M4V, MKV, and WebM. The output keeps the same container and codecs as the input.
Does the trimmed video leave my device?
No. The whole cut happens locally in your browser — up to 1 GB per file.
Can I trim just the audio out of a video?
Yes — use our Audio Trimmer: drop the same video there and it cuts and exports the audio track as MP3, FLAC, or WAV.
Need the words, not just the audio?
SlayScribe turns any audio or video into accurate text in seconds — transcripts, captions, and subtitles in 99 languages.
