   On 10 July 2014, Mozilla released version 2.0, which mainly added trellis quantisation and is now able to reduce the size of baseline JPEGs also. Facebook , Inc. donated 60 000 dollars for the development of the next version, [ 12 ] and CloudFlare assigned a developer for the improvement of MozJPEG.

5. Image file format - Wikipedia

   en.wikipedia.org/wiki/Image_file_format

   The JPEG filename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a significant reduction of the file size.

6. Image compression - Wikipedia

   en.wikipedia.org/wiki/Image_compression

   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.

   Version 3.7 is the current stable release for Windows XP, 7, Vista, or 8. The current version Photoscape X is for Windows 10 and macOS 10.12 or later, with a pro version available for a fee. Older versions are still available for Windows 98 or ME users. It is distributed free of charge for all users, including commercial bodies. [citation needed]

8. JPEG 2000 - Wikipedia

   en.wikipedia.org/wiki/JPEG_2000

   JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.

9. Image conversion - Wikipedia

   en.wikipedia.org/wiki/Image_conversion

   Like any resampling operation, changing image size and bit depth are lossy in all cases of downsampling, such as 30-bit to 24-bit or 24-bit to 8-bit palette-based images. While increasing bit depth is usually lossless, increasing image size can introduce aliasing or other undesired artifacts.
