CompressO

Video files too big to send, and online compressors want uploads that eat bandwidth and risk privacy. CompressO stays local: an open-source tool that compresses videos and images to much smaller sizes locally, drop in a video and shrink it with controllable quality loss, all processed on-device with no upload, easy for messaging and cloud drives. A macOS app, open source.

Features

Video compression: Shrink videos to smaller sizes.
