JPEGmini is described as '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' and is a Image Optimizer in the file management category. There are more than 50 alternatives to JPEGmini for a variety of platforms, including Web-based, Windows, Mac, Linux and Wordpress apps. The best JPEGmini alternative is Caesium Image Compressor, which is both free and Open Source. Other great apps like JPEGmini are ImageOptim, Dinky, TinyFast and OptiImage.
Caesium Image Compressor lets you compress your pictures up to 90% without visible quality loss. Providing a simple yet effective interface with a real-time preview and multiple image processing at the same time, everyone will be able to reach the best result.
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).
Free macOS tool for compressing images, videos, and PDFs—just drag and drop to support numerous formats, flatten or rewrite PDFs, remove metadata, set size targets, preserve quality, and save compressed files alongside originals without internet required.

This program, unfortunately, does not have the same quality and ease of use as “JPEGmini”. Therefore, I can not recommend it, unfortunately.
