PRIVATE BROWSER PROCESSING
Cut a video by watching it, not by guessing timestamps
Play the video, pause where the useful part actually begins, set Start and End, preview the range, then export only that section. The source stays on your device.
Video cutter
The hard part of trimming is finding the moment, not pressing Cut
This tool re-encodes the selected section for more accurate cuts. That is slower than copying around keyframes, but avoids the common problem where a cut starts early or late.
Privacy and limitations
Processing uses FFmpeg WebAssembly locally. The video is not uploaded by this tool. Closing or refreshing the page clears the working file. Speed depends on the browser, device memory, source codec, duration, and resolution, and tools that re-encode are not lossless.
Common questions
How precise are the timestamps?
Start and End accept seconds or minute:second.millisecond values, and the selected range is re-encoded to follow that timing closely.
Is my video uploaded to DJAI?
No. The source file is read and processed in your browser on your device.
Why can the first run take longer?
The browser downloads an FFmpeg WebAssembly core of roughly 31 MB the first time processing is needed; caching can help later runs.
