Cisdem Video Compressor for Mac

Cisdem — macOS Video and Audio Compressor

Cisdem Video Compressor is a macOS utility for shrinking video and audio files while retaining quality. It allows users to target a specific output size or set a desired compression percentage, and it provides three distinct compression approaches to suit different needs. The tool claims it can lower file sizes by as much as 90% without excessive quality loss, making it useful for freeing storage or preparing media for sharing.

Key capabilities

• Choose a target file size or specify the percent reduction you want
• Pick from three separate compression modes to match quality and speed trade-offs
• Preserve playback quality while substantially reducing storage use

Alternative Suggestion — The Unarchiver (Free)

If you prefer a free option, The Unarchiver is recommended as an alternative. It supports many popular container types and offers flexible output and bitrate controls, plus conveniences for previewing and batch work.

Notable features

• Shows an estimated size for the compressed file before you start
• Includes an integrated video player for quick previews
• Supports batch compression for processing multiple files at once
• Offers both constant and variable bitrate settings along with three quality tiers
