jStrip has been discontinued. Similar apps include ImageOptim, which is open source and free for personal use. Other options are RIOT - Radical Image Optimization Tool, TinyPNG, PNGGauntlet and pngquant. Image Optimizers like jStrip are a crowded field, with more than 25 alternatives for Windows, Mac, Linux and the web.
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).

Oxipng is a multithreaded lossless PNG compression optimizer in Rust. It can be used via a command-line interface or as a library in other Rust programs.
Experimental, fast Web PNG/JPG optimizer which offer lossless, visually lossless or lossy compression. it performs image reductions over iterations thanks to recursive multi-processing and multithreading systems.
JPEGmini is a patent-pending photo recompression technology, which significantly reduces the size of photographs without affecting their perceptual quality. The technology works in the domain of baseline JPEG, resulting in files that are fully compatible with any browser, photo...
Curtail (previously ImCompressor) is a useful image compressor, supporting PNG and JPEG file types. It support both lossless and lossy compression modes with an option to whether keep or not metadata of images. It is inspired by .
