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).

Saving images for web/email/other media with the best compression ratio and quality is a difficult task if you don’t have the right tools. Choosing the right format then choosing the right parameters are the key factors of smaller files.


Using advanced lossy compression, TinyPNG reduces PNG file sizes by 50-80%, preserving full transparency and minimizing quality loss. Ideal for web designers, it increases website speed, saves bandwidth, and offers tools like a Photoshop plugin and API for seamless integration.
