Trim Forge
Free online video trimmer. Set IN and OUT, export the clip in your browser. No watermark, no upload, no account.
Trim Forge is a free online video trimmer. Take any video, set an in-point and an out-point, and download the clip between them. No timeline editor, no extra effects, no fluff, just the cleanest possible way to cut a video down to size. Audio comes along by default and pitch stays correct.
Most "trim video online" pages on the open web slap a watermark on the output, cap your file size, force a signup, or send your footage through their server. None of that is necessary anymore. Trim Forge runs the whole job in your browser. Your footage never leaves your machine.
- 01Drop a video file (mp4, webm, mov), or click to pick one.
- 02Play the video. Pause where you want the trim to start, then click Set under IN.
- 03Continue playing. Pause where you want the trim to end, then click Set under OUT.
- 04Pick MP4 or WebM in the Format toggle. MP4 works on Safari and modern Chromium; WebM works everywhere including Firefox.
- 05Decide whether to keep the audio. Off makes a silent clip.
- 06Click Render. Wall-clock time is roughly the OUTPUT clip length.
- 07Download. Files save as <source>-trimmed.mp4 or .webm.
- Output format is your choice: MP4 (H.264) on Safari, Chrome 122+, Edge, and other modern Chromium browsers; WebM (VP9 / VP8) on everything including Firefox.
- Trim points are accurate to about 1/30th of a second. The actual cut may be off by one frame at the very edges depending on the source container.
- Render takes roughly as long as the output clip itself, since the video plays back at 1× during capture.
- Nothing leaves your machine. No upload, no server, no account.
Is Trim Forge free, and does it add a watermark?
Yes, it’s free. No account, no upload, no watermark on the output, ever.
What file formats does it accept and export?
Input: mp4, webm, mov, m4v, and mkv. Output: pick MP4 or WebM in the Format toggle. MP4 (H.264) works on Safari, Chrome 122+, Edge, and other modern Chromium browsers. WebM (VP9 / VP8) works everywhere, including Firefox.
Can I trim from both ends, or just the front?
Both. IN is the start of the kept clip and OUT is the end. Anything before IN and after OUT is discarded.
Where does my video go?
Nowhere. The clip stays in your browser tab. There is no upload and no server processing.
How precise are the trim points?
Frame-accurate to roughly 1/30th of a second. Browsers cannot guarantee perfect sub-frame seeks on every container format, so the actual cut may be off by one frame at the very edges.
How long can my video be?
There’s no hard cap. The practical limit is your browser’s memory. A few minutes is comfortable on most machines.
Does it work on a phone?
Yes. Mobile Chrome and Safari can both render, though longer trims may take longer than on a laptop.
Should I pick MP4 or WebM?
MP4 if you’re uploading to platforms that prefer it (iPhone Camera Roll, iMovie, Premiere, some older CMS, some Discord embeds). WebM if you want a smaller file at the same visual quality, or if you’re on Firefox where MP4 isn’t available. Both play in modern browsers and on most social platforms.
