What video formats can I trim?

You can trim MP4, MKV, MOV, AVI, WebM, and most other common video formats. The output is saved in the same format as the input.

How do I set the start and end times?

Play the video preview to find the exact moment you want, then click 'Set Start' or 'Set End' to capture the current playback position. You can also type times manually in seconds.

Is my video uploaded to a server?

No. All trimming is done inside your browser using FFmpeg.wasm. Your video file never leaves your device.
