Video Trim & GIF
Trim a clip, strip its audio, or turn a section into a looping GIF — all in your browser, nothing uploaded.

🔒 The video is processed only in your browser. It is never sent to a server.
Three quick edits, no software
Drop in an MP4, WebM, or MOV (MKV, AVI, and M4V work too) and pick one of three modes. Trim keeps only the range you set with a start and end time in seconds. Remove audio strips the soundtrack while leaving the picture untouched. To GIF turns a short section into an animated GIF, where you choose the start, duration, frame rate (1-30 fps, 12 by default), and output width in pixels — height scales automatically to preserve the aspect ratio. A built-in player lets you scrub to the exact moment before you set the numbers, and a progress bar tracks the conversion.
When it comes in handy
Trim to cut dead air off the front or back of a screen recording before you share it, or to lift a single scene out of a longer download. Reach for Remove audio when you want a silent background loop, need to drop a music track, or are prepping footage for a slideshow. GIF mode is built for the small, looping clips that chat apps, issue trackers, and docs handle better than video: a three-second bug repro, a UI interaction, or a reaction clip. Because you control the width and frame rate, you can keep the file small enough to paste anywhere — lower them for a tiny file, raise them for a smoother, sharper result.
Local processing, original quality
The whole tool runs on ffmpeg compiled to WebAssembly, executing inside your own browser tab — your video is read straight from disk and never uploaded, so even private or unreleased footage stays on your machine. Trim and Remove audio copy the original video stream instead of re-encoding it, so those outputs are bit-for-bit as sharp as the source and finish quickly; only GIF export re-renders the frames, using Lanczos scaling for clean resizing. The engine is a few-megabyte download the first time you run it and is cached afterward. Since everything is computed on-device, long or high-resolution videos can be slow — trimming first, then converting a short section, is the fastest path.
Frequently asked questions
Is my video uploaded to a server?
No. The tool runs on ffmpeg compiled to WebAssembly inside your browser; the file is read locally and never sent anywhere, which is why even sensitive or unreleased videos are safe to process here.
Why is trimming instant but GIF export slow?
Trim and Remove audio copy the existing video stream without re-encoding, so they finish almost immediately and lose no quality. GIF export has to re-render every frame, and all of it runs on your device, so a longer duration, higher fps, or larger width takes more time — keep the clip short and the width modest for a quick, small result.
Which formats and options are supported?
It reads common videos like MP4, WebM, and MOV (plus MKV, AVI, and M4V). Trim and Remove audio keep the original format and quality; GIF export outputs a looping .gif and lets you set the start, duration, frame rate (1-30), and width, with height scaled automatically to preserve the aspect ratio.
