99.9% Accuracy. Second To None!

best software to compress your images to save at least 70% of bandwidth increasing your load speeds by a whole margin.

Glossy seems to work the BEST for me as the compression is very reasonable not as aggressive as lossy not as passive as losseless giving a good balance between quality retention and compression. I noticed with some images, lossy compression degrades the quality and the final result is pixelated or blurry.

This doesnt happen all the time. However, you dont get that problem with Glossy and the compression size is still very decent (10-20% less than lossy). With the advent of webp, which further reduces image size while preserving 100% of the quality, this no longer becomes a problem.

I would highly recommend shortpixel for your wordpress image optimization needs. Team is superb. Compression is immaculate. Quality is pristine. The best of all worlds!
