In their own words
Caesium Image Compressor
Caesium Image Compressor reduces digital pictures for storage, sending, and sharing, with desktop and online options. The maker says compression can reach 90% without visible quality loss. Desktop tools include a real-time preview, batch processing, resizing, metadata storage options, and folder structure support. Supported formats are JPG, PNG, WebP, and TIFF; both compression modes are available. The online compressor works without a dedicated download, states images never leave your device, and offers a lossless mode that preserves image quality completely. It accepts up to 10 files at once, with a 20 MB limit per file. Caesium also provides command-line tools for image compression. The free software is listed for Linux, macOS, web, and Windows. The current Windows desktop version is v2.8.5 for Windows 10 build 1809 or later, with installer and portable downloads. The macOS version supports macOS 12 or later. Linux users can compile the source or obtain a third-party build; the project README reports testing on Ubuntu 22.04 and Manjaro.
