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.
Drop a video to shrink
Pick a target size or a quality and the bitrate and resolution follow from it, with the projected size shown before anything starts. The encoding runs on this device, through WebCodecs.

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.
Remove Audio
Strips the audio track from a video without touching the video stream.
Video Joiner
Concatenates clips in order, normalising resolution and frame rate when they differ.

Video Crop & Aspect
Crops the frame with a draggable window locked to 9:16, 1:1, 16:9, 4:5 or free, or pads it with bars to a target ratio, then re-encodes on your device.
