How to Trim a Video Online
Drop your video file into the trimmer above, drag the handles on the visual timeline to set your start and end points, and hit export. The tool decodes your video, re-encodes only the selected segment as H.264/AAC MP4, and hands you a download. No account required. No watermark. No upload to any server.
Common use cases include cutting intros and outros from screen recordings, isolating a key moment from a long clip, and trimming webcam footage before sharing. If you need to reduce the file size further after trimming, run the result through the video compressor.
What Is the WebCodecs API?
WebCodecs is a browser API that gives JavaScript direct access to the hardware video encoder and decoder on your device. Instead of relying on FFmpeg compiled to WebAssembly, this tool sends raw frames to the GPU and gets compressed output back at near-native speed.
The result is faster encoding, lower memory use, and real-time preview playback. WebCodecs is supported in Chrome, Edge, and Opera (94+). Firefox support is in development. Because encoding happens on your hardware, your video never touches a remote server.
Why Use a Browser-Based Video Cutter?
Desktop editors like Premiere or DaVinci Resolve are powerful but heavy. For a quick cut, you do not need a 2 GB install. A browser-based video cutter opens quickly, works on any OS, and keeps your files local by default.
This tool processes everything locally using your device’s GPU. Nothing is uploaded, so there are no file size limits imposed by a server. For professional subtitle and caption workflows, check out Velocaption. Explore all free utilities on the tools page.
