Make images Smolr·smolr.io

Smolr is a free, open-source macOS app that compresses and converts image files to make them smaller and more usable. It supports common formats like JPEG, PNG, and GIF as well as modern formats such as WebP, AVIF, and JPEG XL. All image processing happens locally on the user's Mac, so files never leave the device.
