Graphics file extensions and their order of inclusion when not specified
pdftex.def
Version 2011/05/28 v0.06e
The list depends on
- the version of
pdftex.def
, - the version of pdfTeX (temporarily TIFF was available, latest addition is JBIG2),
- the version of the generated PDF (JBIG2 requires PDF 1.4).
For the current versions (2012) and PDF ≥ 1.4, the list is:
.png,.pdf,.jpg,.mps,.jpeg,.jbig2,.jb2,.PNG,.PDF,.JPG,.JPEG,.JBIG2,.JB2
The order of the list is not optimal, it is a victim of compatibility.
The list can be extended by package epstopdf
that adds .eps
to the list and provide means to support further image formats.

List manipulation
I recommend package grfext
for manipulating the list of graphics extensions.
- Extensions can be added:
\AppendGraphicsExtensions
,\PrependGraphicsExtensions
. - Extensions can be removed:
\RemoveGraphicsExtensions
.
For example, prefer vector graphics over bitmap graphics, indenpendent of the driver:
\documentclass{article}
\usepackage{graphicx}
\usepackage{grfext}
\AtBeginDocument{%
\PrependGraphicsExtensions*{
.mps,.MPS,.pdf,.PDF,.eps,.EPS,.ps,.PS,
.png,.PNG,.jpg,.jpeg,.JPG,.JPEG,
.funny,.foobar
}%
\PrintGraphicsExtensions % see .log file
}
\begin{document}
\end{document}
Package grfext
prints the list in the .log
file (example for pdflatex/TL2011):
Package grfext Info: Graphics extension search list:
(grfext) [.mps,.pdf,.PDF,.eps,.png,.PNG,.jpg,.jpeg,.JPG,.JPEG,.jbig2,.jb2,.JBIG2,.JB2]
The star form of \PrependGraphicsExtensions
only adds the extensions that are supported by the graphics driver.
The defaults are defined in the driver files, not by graphicx
itself. A simple way to see them is to use texdef
, e.g. texdef -t pdflatex -p graphicx Gin@extensions
.
For latex
in DVI mode the default extension list is .eps,.ps,.eps.gz,.ps.gz,.eps.Z
, for pdflatex
and lualatex
it is .png,.pdf,.jpg,.mps,.jpeg,.jbig2,.jb2,.PNG,.PDF,.JPG,.JPEG,.JBIG2,.JB2,.eps
and for xelatex
it is .pdf,.eps,.ps,.png,.jpg,.bmp,.pict,.tif,.psd,.mac,.sga,.tga,.gif
