Common Raster Graphics Formats
file extensionMIME typeproper namedescription
.bmpimage/bmpWindows BitmapCommonly used by Microsoft Windows programs, and the Windows operating system itself. Lossless compression can be specified, but some programs use only uncompressed files.
.fpximage/vnd.fpxFlashpix (1.0.2)Uncompressed / lossy, 8-bit grayscale & 24-bit color. Provides multiple resolutions of each image.
.gifimage/gifGraphics Interchange FormatUsed extensively on the web, but sometimes avoided due to patent issues. Supports animated images. Supports only 255 colors per frame, so requires lossy quantization for full-color photos; using multiple frames can improve color precision. Uses lossless, patented LZW compression. This patent expired in the United States in 2003, but is still effective in Europe, Japan and Canada.
.iff .ilbm?Interchange file format / Interleave bitmapFile format popular on the Amiga computer. ILBM is a subtype of the IFF fileformat, which can contain more as just pictures.
.jpeg
.jpg
image/jpegJoint Photographic Experts GroupUsed extensively for photos on the web. Uses lossy compression; the quality can vary greatly depending on the compression settings.
.mngvideo/x-mngMultiple-image Network GraphicsAnimation format using datastreams similar to those of PNG and JPEG, originally designed to replace the use of animated GIF on the web. Free of the patent associated with animated GIF.
.pbm?Portable Bitmap FormatA simple black and white graphics format. It uses 1 bit per pixel. Unlike most graphics file formats, a PBM file is plain text and can be processed with text procesing tools. It is related to the PGM (grayscale) and PPM (color) graphics file formats.
.pcdimage/jpcd ??ImagePac Photo CDProprietary Kodak format, lossy, 24-bit color.
.pgm?Portable Graymap FormatA simple gray scale graphics format. It uses 8 bits per pixel. Unlike most graphics file formats, a PGM file is plain text and can be processed with text procesing tools. It is related to the PBM (black and white) and PPM (color) graphics file formats.
.pngimage/pngPortable Network GraphicsLossless compressed bitmap image format, originally designed to replace the use of GIF on the web. Free of the patent, which expired in 2003, associated with GIF.
.ppm?Portable Pixmap FormatA simple color graphics format. It uses 24 bit per pixel, 8 for red, 8 for blue, and 8 for green. Unlike most graphics file formats, a PPM file is plain text and can be processed with text procesing tools. It is related to the PBM (black and white) and PGM (grayscale) graphics file formats.
.psdapplication/x-photoshopPhotoshop DocumentStandard Adobe format for Photoshop documents. Has many extra features such as image layering. Supported by very few programs other than Adobe Photoshop.
.psp?Paint Shop Pro DocumentStandard Jasc format for Paint Shop Pro documents, similar to .psd for Photoshop. Supported by very few other programs.
.tiff, .tifimage/tiffTagged Image File FormatUsed extensively for traditional print graphics. Lossy and lossless compression available, but many programs only support a subset of available options.
.wbmpimage/vnd.wap.wbmpWireless Application Protocol Bitmap FormatMainly used with WML for wireless devices.
.xbmimage/x-xbitmapX BitMapNative B&W format for the X Window System, supported by most web browsers. An ASCII format which uses no compression designed so that files are in C(++) syntax so images can be included in source code.
.xcf?eXperimental Computing FacilityNative format for the GIMP. Has many extra features such as image layering. Used mostly in the GIMP, but also readable by ImageMagick.
.xpmimage/x-xpmX-PixmapUsed almost exclusively on UNIX platforms with the X Window System, inspired by the XBM format.
??OpenEXRA high dynamic range imaging file format, open sourced by Industrial Light and Magic.

Common Meta-File Formats (either Raster or Vector)

.epsimage/eps ??Encapsulated PostScriptUsed for a PostScript (.ps) output device.
.pctimage/pct ??PictureDefault for pre-OSX Macintoshes (OSX default??)

Common Vector Graphics Formats
file extensionMIME typeproper namedescription
.aiapplication/illustratorAdobe Illustrator DocumentVector format for Adobe Illustrator.
.cgmimage/cgmComputer Graphics MetafileISO Standard - It is used in the aviation industry. (CGM members)\n
.dxfimage/vnd.dxfASCII Drawing InterchangeStandard ASCII text files used to store vector data for CAD programs.\n
.eps?Encapsulated PostScriptA PostScript file that describes a small vector graphic, as opposed to a whole page or set of pages.
.fh?Macromedia Freehand DocumentVector format for Macromedia Freehand.
.fla?Flash Source FileShockwave Flash source file, only usable by Macromedia Flash authoring software.
.pdfapplication/pdfPortable Document FormatA much simplified version of PostScript allowing for files containing multiple pages and links. Works with Adobe Acrobat Reader or Adobe eBook Reader.
.psapplication/postscriptPostScriptGeneric vector-based page description language, created and owned by Adobe. Postscript is a powerful stack-based programming language. Supported by many laser printers.
.svgimage/svg+xmlScalable Vector GraphicsAn XML based vector graphics format, as defined by the World Wide Web Consortium for use in web browsers.\n
.swfapplication/x-shockwave-flashFlashFlash is a web page plug-in that displays vector based animations contained in SWF files. Several applications can create SWF files; these include the Flash authoring tool from Macromedia.
.wmfimage/x-wmfWindows MetafileStores vector graphics and raster graphics as a sequence of commands to be issued to the graphics layer of the Microsoft Windows operating system.\n
Some file formats, e.g. PDF, allow both raster and vector graphics. This is because the underlying PostScript system of the Portable Document Format is designed to handle both methods of creating graphics.
