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).

Compress images, videos, and PDFs directly on your Mac with local batch processing, no internet required, and full privacy. Features drag-and-drop workflow, smart quality preservation, on-device optimization, and subscription options for premium tools.




Optimize PNG, JPEG, WebP, and SVG images efficiently with flexible lossless and lossy compression modes, metadata control, and safe mode to avoid data loss, using tools like oxipng, jpegoptim, scour, and cwebp, enhancing image storage and load efficiency.

Compress images with pixel-perfect precision using advanced algorithms that preserve quality while dramatically reducing file sizes.



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.
