ImageMagick uses an ASCII string known as magick (e.g. GIF) to identify file formats, algorithms acting as formats, built-in patterns, and embedded profile types.

Support for some of the formats are delegated to libraries or external programs. The Installation Guide describes where to find these distributions and any special configuration options required.

To get a complete listing of which image formats are supported on your system, type

$magick> identify -list format

On some platforms, ImageMagick automagically processes these extensions: .gz for Zip compression, .Z for Unix compression, .bz2 for block compression, and .pgp for PGP encryption. For example, a PNM image called image.pnm.gz is automagically uncompressed.

ImageMagick supports reading over 100 major file formats (not including sub-formats). The following table provides a summary of the supported image formats.

Select order with filename, e.g. hald:5 for order 5.

This file format is identical to that used by ImageMagick to represent images in memory and is read by mapping the file directly into memory. The MPC format is not portable and is not suitable as an archive format. It is suitable as an intermediate format for high-performance image processing. The MPC format requires two files to support one image. Image attributes are written to a file with the extension .mpc, whereas, image pixels are written to a file with the extension .cache.

Some PDF files, however, have a CropBox or TrimBox that is smaller than the MediaBox and may include white space, registration or cutting marks outside the CropBox or TrimBox. To force ImageMagick to use the CropBox or TrimBox rather than the MediaBox, use -define (e.g. -define pdf:use-cropbox=true or -define pdf:use-trimbox=true). Use -density to improve the appearance of your PDF rendering (e.g. -density 300x300).

If PNM is used as the output format specifier, then ImageMagick automagically selects the most appropriate format to represent the image. The default is to write the binary version of the formats. Use -compress none to write the ASCII version of the formats.
PPM	RW	Portable pixmap format (color)
PS	RW	Adobe PostScript file	Requires Ghostscript to read. To force ImageMagick to respect the crop box, use -define (e.g. -define ps:use-cropbox=true). Use -density to improve the appearance of your Postscript rendering (e.g. -density 300x300).

WMF	R	Windows Metafile	Requires libwmf. By default, renders WMF files using the dimensions specified by the metafile header. Use the -density option to adjust the output resolution, and thereby adjust the output size. The default output resolution is 72DPI so -density 144 results in an image twice as large as the default. Use -background color to specify the WMF background color (default white) or -texture filename to specify a background texture image.
