And perhaps most importantly, Lena was used to develop the now-ubiquitous .JPEG image format, a compression scheme that allows complex digital files to transfer between devices and appear on . Because JPEG compressions often result in noise, and the resulting JPEG does not store it's current compression level, secondary compressions (i.e Original -> Quality=60 ->Quality=80) will often be larger than the primary compression. I've run this test using both GD and desktop compressors (see my original link).
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data. [1]Comparison of JPEG images saved by .Sample JPG files are example image files saved in the JPEG (Joint Photographic Experts Group) format. JPEG is a commonly used method of lossy compression for digital images, particularly for those produced by digital photography. JPG files are known for their balance between image quality and file size, making them ideal for various applications. Optimole is an all-in-one image optimization solution for WordPress.. What makes Optimole stand out is that instead of compressing images locally and then replacing them in your media library permanently, Optimole does everything in the cloud – so there is no slowing down of your website.

Lossy compression are irreversible, that is once the data gets lost, it is not .
Lossy compression results on the New Test Images. Results measure visual-quality of images compressed at different bit-rates by various algorithms. Higher SSIM value means better visual quality of compressed image. Higher quality at same bit-rate means better results. Click on the images to enlarge, you can enlarge multiple images at same time.Overview of JPEG 1.

The Smush image compression algorithm can reduce the image file size significantly without loss of image quality. Smush Image Compression Test. In our image compression test, we found Smush reduced image size from 200 KB to 190.8 KB (4.6%) using lossless compression. What’s Good About Smush?UPDATE: As a commenter mentioned, 100% quality still does not mean lossless compression when using JPEG. Loading the image, doing something to it, and then saving it again will ultimately result in image degradation. If you need to alter and save an image without losing any of the data you need to use a lossless format such as TIFF, PNG or BMP.
