How to Trim a Video: Cut Start & End Points — Free
A screen recording with a dead ten seconds at the start, a phone clip you only want the middle of, a video that needs to lose its outro before you post it somewhere with a length limit — here's how to trim a video down to just the part you need, right in your browser.

Open Video TrimmerWhich situation needs this?
| Situation | What trimming fixes |
|---|---|
| Screen recordings | Cut the few seconds of setup/countdown before the actual demo starts |
| Phone clips | Pull out just the moment worth keeping from a longer recording |
| Upload length limits | Shorten a video to fit a platform's duration cap before uploading |
| Removing an outro/intro | Drop a boring lead-in or a trailing "thanks for watching" segment |
The tool uses two plain start/end fields in seconds rather than a drag-handle timeline — it's built for a quick, precise cut, not for frame-by-frame video editing.
Does trimming lose quality?
It depends on what you cut. If the start point stays at 0 and you're only shortening the end, the video stream is cut directly without touching a single frame — no re-encoding, no quality loss at all. If you move the start point forward too, the video needs to be re-encoded from that exact frame so it starts cleanly; that happens automatically at high quality, so the difference is generally not noticeable, but it's not a byte-for-byte copy in that case.
FAQ
How do I cut a video down to a specific clip?
Upload the video at Stelluna's Video Trimmer, set the start and end time in seconds, and click Trim.
Is it free?
Yes — no account, no watermark, no limit on how many videos you trim.
Does my video get uploaded anywhere?
No. Trimming happens entirely in your browser, using your device's own video processor — your video never leaves your device.
What format will the downloaded clip be?
The same format as your source video whenever possible (MP4 stays MP4, WEBM stays WEBM). Formats the tool can't target directly, like AVI, fall back to MP4 (H.264 + AAC).
Is there a file size limit?
Yes, up to 300MB, to keep the trim running smoothly in your browser.
