There are six alternatives to ImgBoost, not only websites but also apps for a variety of platforms, including Mac, SaaS, Adobe Photoshop and Docker apps. The best ImgBoost alternative is ImageOptim. It's not free, so if you're looking for a free alternative, you could try ImageOptim or RasterFox. Other great sites and apps similar to ImgBoost are TinyJPG, Kraken Web Optimizer and Thumbrella.
ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It's useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization).
