2. Image compression - Wikipedia

   en.wikipedia.org/wiki/Image_compression

   The best image quality at a given compression rate (or bit rate) is the main goal of image compression, however, there are other important properties of image compression schemes: Scalability generally refers to a quality reduction achieved by manipulation of the bitstream or file (without decompression and re-compression).

3. QOI (image format) - Wikipedia

   en.wikipedia.org/wiki/QOI_(image_format)

   The Quite OK Image Format (QOI) is a specification for lossless image compression of 24-bit (8 bits per color RGB) or 32-bit (8 bits per color with 8-bit alpha channel RGBA) color raster (bitmapped) images, invented by Dominic Szablewski and first announced on 24 November 2021.

4. Image file format - Wikipedia

   en.wikipedia.org/wiki/Image_file_format

   An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed.

5. JBIG2 - Wikipedia

   en.wikipedia.org/wiki/JBIG2

   JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group.It is suitable for both lossless and lossy compression. . According to a press release [1] from the Group, in its lossless mode JBIG2 typically generates files 3–5 times smaller than Fax Group 4 and 2–4 times smaller than JBIG, the previous bi-level compression standard released by

   WhatsApp doesn’t take a large space on your phone compared to some games and apps. When you take the backup of your WhatsApp account, all these files are backed up too. Sadly, there’s no way ...

9. Lossless JPEG - Wikipedia

   en.wikipedia.org/wiki/Lossless_JPEG

   Typically, compressions using lossless operation mode can achieve around 2:1 compression ratio for color images. [5] This mode is quite popular in the medical imaging field, and defined as an option in DNG standard, but otherwise it is not very widely used because of complexity of doing arithmetics on 10, 12, or 14bpp values on typical embedded 32-bit processor and a little resulting gain in ...
