  2. Image compression - Wikipedia

    en.wikipedia.org/wiki/Image_compression

    JPEG was introduced by the Joint Photographic Experts Group (JPEG) in 1992. [12] JPEG compresses images down to much smaller file sizes, and has become the most widely used image file format. [13] JPEG was largely responsible for the wide proliferation of digital images and digital photos, [14] with several billion JPEG images produced every ...

    [5] [6] This technology is integrated into JPEGmini Pro allowing users to reduce the file size of their photos and videos with limited quality reduction. JPEGmini technology is built around a perceptually aligned image quality measure, which reliably determines the maximum amount of compression which can be applied to each individual image or ...

    If the new version is too sharp, you can utilize the blur filter or tool to fix this, or use Colors > Levels to mess with the Alpha channel. Once it looks correct, save the image as a PNG. Then, to reduce file size, run it through a program like ImageMagick that supports 8-bit PNGs with alpha transparency, in order to remove any unnecessary ...

    It was designed by Google to reduce image file size to speed up web page loading: its principal purpose is to supersede JPEG as the primary format for photographs on the web. WebP is based on VP8 's intra-frame coding and uses a container based on RIFF .

  7. Image editing - Wikipedia

    en.wikipedia.org/wiki/Image_editing

    Many image file formats use data compression to reduce file size and save storage space. Digital compression of images may take place in the camera, or can be done on the computer with the image editor. When images are stored in JPEG format, compression has already taken place.

  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.

    Image Analyzer - Amongst other things, allows for lossy compression of PNG files. (Often, however, merely posterizing the image at a level that does not produce color banding results in smaller files of the same or higher quality.) JPG Cleaner - Removes Exif data from JPEGs, making the files smaller.
