Wofür ist video trimmer geeignet?

Video trimming exports a short clip from a local video. After the user enters a start time and duration, the tool calls ffmpeg.wasm in the browser and exports MP4.

The first version uses lightweight inputs instead of a full timeline. Keep the original file and preview the result before downloading.

Unterstützte Formate: MP4, MOV, WebM, AVI; Einzeldateilimit: 500MB.
