Caesium Image Compressor · Reduce product image weight before upload
Compress images and adjust dimensions through a desktop graphical interface to establish a repeatable local listing workflow.
Requirements
Windows/macOS is easier: 64-bit Windows 10 1809+ or macOS 12+. Linux requires building from source or verifying a third-party package separately. The software is free.
Quick start
On the official release page, select the Windows installer/portable ZIP or Mac DMG. This version has no official Linux binary package.
Suitable for store owners who frequently handle SKU images; local processing does not depend on paid APIs. After lossy compression, check fine textures and text; it is not an image repair tool.
