I’ve been using EWWW image optimiser to compress all of my जेपीईजी तथा पीएनजी images on this site for several years. EWWW makes use of OptiPng and PngOut and whilst these are powerful tools there are alternatives out there now that I wanted to test and compare.
I am aware of newer image formats that may offer smaller sizes but until they are broadly supported we will have to continue to work with पीएनजी तथा जेपीईजी.
I have already seen some comparisons showing some impressive performance by some other formats but I wanted to test this for myself with my realworld images. Based on the claims presented I decided to start with Pingo and see how much it reduced the size of my total image library.
वहाँ रहे हैं 3549 छवियों जो PNG का का मिश्रण हैं, JPEGs, and Webp files and range in size from over 1000×1000 pixels to small thumbnails of 60×60 pixels.

3505 images were processed in 434 seconds which is impressively quick compared to the previous tools I’ve used. कैसे कभी, केवल 3455kb (3.37एमबी) बचा लिया गया था जो एक है 2.5% बचत.
Despite the lack of reduction, I will still be looking to migrate to pingo as it is vastly faster than the tools used by EWWW and achieves effectively the same result

Lossy compression was much more impressive in size reduction with a 22.6Mb (19%) reduction but this is to be expected as my previous tools were not using lossy compression. I had decided in advance that a significant reduction would be needed for me to consider using lossy compression. This reduction is right on the borderline. The ultimate decision comes down to how much the smaller dimension (अधिक बार प्रस्तुत) images saved — the majority of the savings were with original images not with the smaller images so I’m not persuaded that the reduction is worthwhile at this point, especially as I already serve webp images to over 50% of visitors and these gained the least
The next step is to figure out how to automate the process with pingo which isn’t supported by EWWW.
