Video Trimmer
Cuts a clip between two timestamps, copying streams without re-encoding when the cut is on a keyframe.
Video Converter
Reads MP4, MOV, WebM and MKV and writes MP4 (H.264 + AAC) or WebM (VP9 + Opus) with quality and resolution settings. When only the wrapper changes — MOV to MP4, MKV to WebM — the streams are copied untouched.
Video Compressor
Re-encodes to a target file size or a quality preset, stepping the resolution down when the bitrate would starve it, and shows the projected size before it starts and the actual size after.
Remove Audio
Strips the audio track from a video without touching the video stream.
