The video trimmer lets you drag a start and end handle along a visual timeline to select the range you want to keep. You can type precise timestamps for sample-accurate cuts, or scrub frame by frame to find the right in and out points. The preview plays only the selected range, so you can confirm the cut before exporting.
Typical uses include cutting the silent lead-in and tail off a screen recording, extracting a short clip from a longer talk for social media, or quickly producing a short teaser from a full interview. Because the tool re-encodes only the selected range, the output file is proportionally smaller than the original.
The trim runs entirely in your browser using WebCodecs. No uploads, no watermarks, no file size limit beyond what your device can hold. The output is a standard MP4 that plays on every device and platform.
Video Trimmer — Frequently Asked Questions
How do I cut a specific part of a video?
Drop your clip, drag the start handle to the beginning of the section you want, drag the end handle to where it should stop. Type exact timestamps into the input boxes for sample-level precision. Preview to confirm, then Export — only the selected range ends up in the output file.
How precise is the trim?
The trim is accurate to the millisecond. Keyframe-aligned cuts are instant (no re-encode); sub-keyframe cuts trigger a small re-encode of the boundary frames so the output starts and ends exactly where you asked.
Can I keep multiple segments from one video?
This tool trims to a single start/end range per export. For multiple segments, trim each one separately and merge the outputs with a concat step (ffmpeg or iMovie). A multi-segment version is planned.
Does trimming reduce video quality?
For keyframe-aligned cuts there's zero re-encoding — the output is bit-identical to the source within the selected range. Sub-keyframe cuts involve a tiny re-encode at the boundaries; picking the High or Ultra preset keeps that imperceptible.
What video formats can I trim?
MP4, WebM, MOV, MKV, and most other browser-decodable formats. Output is MP4 for maximum compatibility, regardless of input format.
Is my video uploaded during trimming?
No. All trimming runs in your browser via WebCodecs. Your video never leaves your device.
