To compress the original camera images I used PhotoFiltre,, a great free photo-edting programme by Antonio Da Cruz. By adjusting the quality level for each image, I was able to generate files with the same size as the corresponding JPEGmini files.

When saving a JPEG file, most software allows the selection of a quality level, usually on a scale. So far, good news …īut how good Is it? To access the value of JPEGmini’s optimized JPEG compression, I used ordinary JPEG to compress several of their example image files. image sets (before and after JPEGmini processing), I observed little or no loss of detail or introduction of distortion, quantization, etc. Sounds impressive, but is it? After downloading several demo. JPEGmini compression of up to 5x, therefore implies an overall compression of about 15x. This is due to the natural statistics of image data, and is routinely done with little or no apparent loss or distortion. These are already compressed by the processing of digital cameras by about 3x. However, the claims of virtually no loss of image quality got me interested, so I devised an experiment to verify the claims, and evaluate JPEGmini’s performance.īackground: JPEGmini’s claims are based on the compression of JPEG files. Compression up to 5x was touted, which is not very impressive to people developing image compression. Recently I was made aware of JPEGmini,, a product that is described as optimized JPEG compression for your photos.
