About

Caesium Image Compressor lets you reduce picture file sizes by up to 90% without visible quality loss, delivering a free, open source solution designed for both simplicity and effectiveness. It offers a clean, real-time preview interface and batch processing so photographers, bloggers, webmasters, businesses, and casual users can optimize image libraries for storage, sharing, or web use while retaining visual fidelity. Advanced features include metadata preservation options and folder-structure support for streamlined workflows, and Linux or macOS users can harness the command-line tool for rapid, script-driven compression. For quick tasks or occasional use, the online compressor handles multiple images directly in your browser without any installation. Available as an installer or portable ZIP for Windows 10 (build 1809+) and as a DMG for macOS 10.15+, Caesium balances ease of use and advanced control across platforms.
