Portable Network Graphics (PNG) was designed as a replacement for GIF in order to avoid infringement of Unisys' patent on the LZW compression technique. [42] PNG offers better compression and more features than GIF, [59] animation being the only significant exception.
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 ...
WebP is a format invented by Google that was intended to replace PNG, JPEG, and GIF. [61] WebP files allow for both lossy and lossless compression, while PNG only allows for lossless compression. WebP also supports animation, something that only GIF files could previously accomplish. [62]
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.
Some image file formats, like PNG or GIF, use only lossless compression, while others like TIFF and MNG may use either lossless or lossy methods. Lossless audio formats are most often used for archiving or production purposes, while smaller lossy audio files are typically used on portable players and in other cases where storage space is ...

Lossless compression in particular provides the same information as a bitmap in a smaller file size. [8] TIFF and JPEG have various options. JPEG is usually lossy compression. TIFF is usually either uncompressed, or lossless Lempel–Ziv–Welch compressed like GIF. PNG uses deflate lossless compression, another Lempel-Ziv variant.
