VideoSlim

macOS target-size compressor

VideoSlim

Compress any video to a target size in MB — for email, chat, and upload limits.

Most compressors offer quality presets. VideoSlim aims at a size in MB, analyzes codec, resolution, bitrate, duration, audio, and subtitles first, then explains the strategy. Processing stays on the Mac.
