JPEGmini is an excellent JPEG/JPG image automatic compressor from Israel, originally only exists in the form of online web service. It comes with a unique algorithm that can imitate the human visual system, which can automatically analyze and get the available maximum compression ratio of photos on the premise of maintaining the same level of image quality.
They claimed that JPEGmini can reduce the photos’ size up to 50%~80% (for photos above 8 million pixels) “without loss” on image quality. Note: the standard of “no quality loss” here means that for the human eyes it is difficult to distinguish what the difference is before and after the compression. This ability is amazing. Because JPG/JPEG image format itself is a lossy compression format, and most often they have been compressed.
Through actual tests, the compression effect of JPEGmini is better Photoshop when processing larger images; While for smaller pictures, using Photoshop’s “save for web page format” (in 60% quality) makes better performance.
Another thing that is worthy of mentioning is, JPEGmini is capable of keeping the metadata of digital photos, which is helpful for photographers or graphics designers.
Professional photographers who just like to use the RAW format to store photos may not need JPEGmini at all. However, for other users like web designers or graphic designers, it becomes pretty useful. BTW, if you are finding a solution for JPEG lossless compression (which is essentially a second transcoding), you can try jpegtran (a command-line tool) instead.
How To Install ?
- Download and extract
- Run ‘loader.exe‘ (or ‘JPEGminiPro.exe‘) as administrator (just the first time) to launch program, instead of the original ‘JPEGminiPro.exe’
