DescriptionJPEG is the most common image format used by digital cameras, it is the most common format for storing and transmitting photographic images on the World Wide Web.PNG was created to improve GIF image-file format. Removing patent license issues at that time; and removing 256 colors limitation.WebP is an image file format developed by Google, and supposed to be a new open standard for lossily compressed true color graphics. It's a direct competitor to JPEG.SVG is an XML based file format. It allows to create vector graphics with animation and interaction support. It can be edited with any text editor.AV1 Image File Format is a recent image format based on the AV1 video codec and with a wide feature set.GIF is a bitmap image format that allows a lossless compression by reducing the image to 256 distinct colors. It has been replaced by PNG after fear over patent issues. It is still widely used for animation as it's the only format that supports animation and that is widely supported by browsers.JPEG XL is the next generation image format, with the ambition to replace the old JPEG format for the long term.JPEG 2000 is an enhancement of the JPEG standard. It supports transparency, is able to store lossless data. It is also having a better compression level. As it is unsupported by several browsers, it has not been widely used on the Internet.BMP File Format as been widely used on Windows platform. Although it supports data compression and alpha channels, these features were not widely used as it was not supported by all image editors.RAW relates to several image file formats since each camera manufacturer has one or several formats (depending on equipments). These files contains the data acquired by sensors almost unprocessed.TIFF is a file format for storing images losslessly. It is widely supported by image-manipulation applications, by scanning, faxing, word processing, optical character recognition and other applications.EPS is a file extension for a graphics file format used in vector-based images in Adobe Illustrator. EPS stands for Encapsulated PostScript. An EPS file can contain text as well as graphics.High Efficiency Image File Format is a container format developed by the Moving Picture Experts Group (MPEG). The format has several variants and supports individual or sequences of images.PICT is a graphics file format introduced on the original Apple Macintosh computer as its standard metafile format. It allows the interchange of graphics (both bitmapped and vector), and some limited text support, between Mac applications, and was the native graphics format of QuickDraw.PCX, standing for PiCture eXchange, was the native file format for PC Paintbrush and became one of the first widely accepted DOS imaging standards, although it has since been succeeded by more sophisticated image formats.PDF is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.PSD is the default image file format used by Adobe Photoshop. It supports layers and transparency.TGA format is used widely in paint, graphics, and imaging applications that require the storage of image data containing up to 32 bits per pixel. TGA has also become popular in the world of still-video editing.WMF is an image file format intended to be portable between applications and may contain both vector graphics and bitmap components. It acts in a similar manner to SVG files.
