Cut a clip down and shrink the file size — all processing happens on your device, nothing is uploaded anywhere. Free, no account needed.
First use downloads a ~30MB video engine (one time, then cached by your browser). Processing runs entirely on your device's CPU, so it's slower than a phone app — a short clip usually takes well under a minute, longer ones more.
Trim a clip and shrink its file size without installing anything and without uploading your footage. The Video Trimmer & Compressor runs FFmpeg in your browser via WebAssembly, so your video is processed on your own device — ideal for private recordings, unreleased game footage or anything you do not want on a random server.
Cut the start and end, pick a target quality or size, and export an MP4 that plays everywhere. It is the quickest way to turn a two-minute screen recording into a ten-second GIF-sized clip for a Discord post, a bug report or a store page.
No. FFmpeg runs inside your browser as WebAssembly. The file stays on your device the whole time; you can even disconnect from the internet after the page has loaded.
Encoding happens on your CPU through WebAssembly, which is slower than a native install. For long 4K clips, trim first, then compress — or reduce the resolution.
MP4 (H.264 + AAC), the most compatible format for web, Discord, Slack and social media.
Practically it depends on your device's memory. Files up to a few hundred megabytes work on a normal laptop.
