In addition I also used a customized measurement of 400 x 400 pixels for the test.
These are the sizes that you would normally use as a featured image or as a thumbnail while showing sidebar or associated posts. I am not showing the final optimized images here as that is unimportant considering that all outputs are quite excellent and look really close to the original image.
So let's begin: I evaluated 2 JPEG images of different sizes with these three plugins. The output information of each of these images is listed in a tabular format for easy reference. The very first image had a measurement of 640 x 427 Pixels and total size of 116 KB.Visit the following link to see the image that was used: 640 x 427 Pixels 116 KB Here is a small sneak peek of the image utilized: The outcomes are listed as follows.
Subsequent columns show the size of the last enhanced image by TinyPNG, WP Smush and EWWW Optimizer. Each row information the image sizes for a particular image dimension particularly the initial image, thumbnail, medium and custom-made size. 640x427 px (Original Size)116 KB79 KB108 KB108 KB150x150 px (Thumbnail)9 KB9 KB8 KB8 KB300x300 px (Medium)29 KB29 KB27 KB27 KB400x400 px (Customized Size)47 KB38 KB45 KB45 KB This image had a measurement of 640 x 426 Pixels and total size of 226 KB.
Compression outputs of EWWW and WP Smush are precisely the very same most likely due to the fact that they use the very same software application JPEGTran which offers lossless compression. Lossless compression as discussed before maintains the initial image quality but as a down side does not give max compression. Paid versions of both these plugins utilize lossy compression which will provide far better results.
