Best Image Compression Software in 2026
Updated
For a site, app, or image workflow where file size matters, compression tools vary in the ways they process and prepare images. Compare compression modes and supported formats, then consider batch processing, resizing, and maximum upload size against your typical workload. Metadata controls may be relevant when image information needs attention, and API access can matter when compression is part of a system rather than a manual step. TinyPNG, Fastly Image Optimizer, and Kraken.io are among the products covered. Free-plan availability and paid-from pricing add cost context as you weigh the listed capabilities.
