About trimming a video
This cuts a video down to a chosen range without uploading it. It plays the selected part of the source and re-records it from a canvas using the browser's own `MediaRecorder`, so it works in every current browser and needs no ffmpeg. The output is a fresh file containing just the part you kept.
The trade-off of this approach is that it runs in real time — a 30-second result takes about 30 seconds to produce — and the video is re-encoded, so there's a small quality change (usually invisible on short clips). That's why it's aimed at short cuts: grabbing a highlight, dropping a slow intro, clipping a moment to share.
The container is MP4 where the browser can record it (Chrome, Safari) and WebM otherwise. For frame-exact cuts on a long file with no re-encode, a desktop editor is still the better tool — but for a quick trim that never leaves your device, this does the job.
Supported files
Accepts any video your browser can play (MP4, MOV, WebM…). Produces an MP4 or WebM clip.
Is my file uploaded?
No. The clip is played and re-recorded entirely in your browser with MediaRecorder — nothing is sent to a server.
Common problems
- It's taking a long time
- Trimming runs in real time — the wait is roughly the length of the part you're keeping. Pick a shorter range.
- The output is WebM, not MP4
- Your browser can't record MP4. The WebM plays in every modern browser; convert it afterwards if you need MP4 specifically.

Trim Video — frequently asked questions
Is my video uploaded?+
No. The clip is re-recorded from a canvas in your browser — nothing is sent anywhere.
Why does it take as long as the clip?+
This trims by playing the selected part and re-recording it in real time, so a 30-second clip takes about 30 seconds. It's the simplest approach that works in every browser.
Is the video re-encoded?+
Yes — the output is a fresh recording, so there's a small quality change. For short clips it's hard to notice.
What format do I get?+
MP4 where your browser supports recording it (Chrome, Safari), otherwise WebM.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
