File Extension	Image Format	Description
.jpg	JPEG	JPEG is a 1992 standard, named by the the Joint Photographic Experts Group which has developed it. JPEG is used for lossy image compression. JPEG is a shortform for the graphic format JFIF which is used for storage of JPEG- compressed images. JPEG is the most widely used web graphics format for photos.
.tif	Tagged Image File Format	The Tagged Image File Format (TIFF or short TIF) is a file format for storing image data. The TIF was originally created by Aldus (1994 Adobe over), and Microsoft for scanned raster graphics for the color separation.
.png	Portable Network Graphics	Portable Network Graphics (PNG) is a graphics format for raster graphics. It was developed as a free replacement for the older GIF format which is less complex than TIFF. The images are lossless compressed.
.pcx	PiCture eXchange	PCX (PiCture eXchange) is a file format for storing image data. The PCX-Format was developed 1982 by the company ZSoft who used it in their own products Paintbrush and FRIEZE (residents assistance program to import images from other applications such as Lotus 1-2-3). As Paint Brush has been delivered with Windows this format quickly spread. Today it is supported by almost every Graphicsapplication.
.tga	Targa Image File Format	The Targa Image File Format (in short, TGA, conventional file extension:.tga) is a file format for storing images. Targa stands for "True Vision Advanced Raster Graphics Array". The Targa file format was originally developed 1984 from the company True Vision. 1989, it was expanded to thumbnails for Alpha channel, gamma correction and text as metadata information to include. The data is stored up to 32 bits per pixel as a raster graphic (bitmap) either uncompressed or with a barrel length coding lossless compression.
.bmp	Bitmap	Windows Bitmap or device independent bitmap (DIB) is a two-dimensional raster graphics format used for the operating systems Microsoft Windows and OS / 2 and Windows 3.0.
.psd	Photoshop Document	Photoshop Document is a proprietary file formats from Adobe Photoshop.
.pcd	Kodak Photo CD	The Kodak Photo CD is a standard Compact Disc (CD-ROM) for the digitalization and archiving of photographs. The Photo was developed by the Eastman Kodak Company and Philips on the basis of CD-i-Bridge-Spezifikation and 1992 introduced to the market.
.gif	Graphics Interchange Format	The GIF Graphics Interchange Format (graphic exchange format) is a graphics format with good lossless compression for images with low color depth (up to 256 different colors per image). In addition it supports several images in a single file.
.wmf	Windows Metafile	Windows Metafile (WMF) is a proprietary graphics format of the Microsoft Company. It was developed for the exchange of graphics on various programs e.g. the Windows clipboard.
.emf	Windows Enhanced Metafile	Enhanced Windows Metafile (EMF) is a further development of the Microsoft Windows Metafile graphics file format (WMF). It combines scalable vector graphics with the ability to raster graphics.
.jbig2	JBIG	JBIG is a standard for a lossless compression methods of digital images. The abbreviation is an acronym of the editors group Joint Bi-level Image Experts Group, which is a part of the JPEG format created by Joint Photographic Experts Group.
.jpeg2000	JPEG 2000	JPEG 2000 is a standard (ISO 15444) for image compression based on the discrete wavelet transform (DWT). As the JPEG he is known by the Joint Photographic Experts Group issued. JPEG 2000 dominated both lossless and lossy compression.
