WebP is a raster graphics file format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, [8] as well as animation and alpha transparency. Google announced the WebP format in September 2010, and released the first stable version of its supporting library in April ...
The PNG (Portable Network Graphics) file format was created as a free, open-source alternative to GIF. The PNG file format supports 8-bit (256 colors) paletted images (with optional transparency for all palette colors) and 24-bit truecolor (16 million colors) or 48-bit truecolor with and without alpha channel – while GIF supports only 8-bit ...

AVIF was designed by the foundation to make up for the shortcomings of other image codecs, including PNG, GIF, and WebP. [64] AVIF is generally smaller in size than both WebP and PNG. [65] AVIF supports animation while PNG does not and has a superior image quality when compared to PNG. [66]
High Efficiency Image File Format (HEIF) is a digital container format for storing individual digital images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text , audio and video.
When saving a JPEG, the graphics program will let you choose the compression level. Usually the values range from 0 to 100 where 100 is the best quality possible with very little compression applied. Some apps, notably Paint Shop Pro, reverse this scale with 0 as highest quality and 100 as the lowest quality. Don't mistake the 0 to 100 scale ...
Some high compression algorithms require high processing power. The quality of a compression method often is measured by the peak signal-to-noise ratio. It measures the amount of noise introduced through a lossy compression of the image, however, the subjective judgment of the viewer also is regarded as an important measure, perhaps, being the ...
It is based on the intra-frame encoding of the High Efficiency Video Coding (HEVC) video compression standard. [2] Tests on photographic images in July 2014 found that BPG produced smaller files for a given quality than JPEG, JPEG XR and WebP. [3]
