These options are available for single images, but can be applied to batches of images as well. To do this, instead of opening a single image at a time, select a number of them in the Finder and likewise right-click to open the selection in Preview.
When opening them in this manner, they will be gathered in a single Preview window that will list them as thumbnails to the left of the main viewing area. With this view, you can then hold the Command key and select some of the images in random order, use the Shift key to select a series of images in order, or select one and then press Command-A to select all of them.
With your desired images selected, the Export option in the File menu will change to Export Selected Images, which will give you the same options to save them in the desired format. Do keep in mind that when using batch conversions you will not be able to name the files differently, so they will keep their original names but have a new file type suffix associated with them.
Several online services to convert djvu files to pdf (and other file format conversions):

a tool converting PostScript and PDF files into various vector graphic formats.
A simple Python script that converts CHM files into PDF files. Requires: chmlib pychm htmldoc (Old versions require pdftk too) All of these should be in your favourite distro repository. Currently it works on Linux.
a commandline tool for OS X that converts 24-bit PNG images to 8-bit PNG. Most common graphic programs can’t export to 8-bit PNG with alpha transparency even though it’s by far the most useful file format for the web.
python based ebook conversion tools @ Google Project Hosting.
The purpose of this project to to collect, maintain, and provide a home for many of the publicly available standalone tools to convert ebooks from one format to another. In addition, gui front-ends will be hosted for many of the command line tools that already exist. Most of the tools here will be python based and cross-platform in nature.
It includes MobiUnpack, which will extract html and image files from a mobi ebook. When you’ve finished editing them you turn them back into a mobi file with mobicreator.
Another alternative is using the internal conversion by Calibre.

For the GIMP, David’s Batch Processor or using it in batch mode via terminal.
Using the terminal in Linux, Imagemagick is very powerful, with its mogrify command.
In Windows, many of the image processing programs listed at Portable freeware can operate in batch mode.
Using built-in utility in Mac OS X’s Preview. Some argue that Preview is, indeed, the Best Batch Photo Resizer for Mac.
Automator can come to the rescue very easily. Step by step instructions.
Images can also be processed by Python and Perl (with the respective help of PythonMagic and PerlMagick, an interface to the popular ImageMagick suite of command line tools to do just this kind of stuff. Or its fork, Graphicsmagick ), of course PHP, Ruby…
Python’s PIL (image library) comes also handy for the task.
Converting a Type1 font to TrueType is a piece of cake. Being an old fashioned command line person, I use Fontforge’s scripting facility to convert my fonts. This is script cvt.pe:
Open($argv[1]) Generate($argv[1]:r+".ttf","",0)
To run it, put the Type1 font in your current directory together with it’s associated metrics file, for example:
NimbusSansL-Regu.pfb NimbusSansL-Regu.afm
Make sure you have installed the fontforge program in your execution path, and issue the following command:
fontforge -script cvt.pe NimbusSansL-Regu.pfb
Fontforge will produce some lines of output similar to:
Copyright (c) 2000-2004 by George Williams.
Executable based on sources from 08:11 3-Jul-2004.
FontForge used to be named PfaEdit.
When you look in your directory, you’ll see two new files:
NimbusSansL-Regu.g2n NimbusSansL-Regu.ttf
The file NimbusSansL-Regu.ttf is the newly created TrueType version of the original Type1 font. You can drop it in your personal OpenOffice.org fonts dir and OOo will pick it up automatically.
You can also use this facility when you want to use fonts on Microsoft Windows systems that do not have the capabilities installed to handle Type1 fonts.
For the sake of completeness, the following script will generate a .pfb and .afm pair from TrueType fonts:
Open($argv[1]) Generate($argv[1]:r+".pfb","",1)

A Linux / Windows utility that translates PostScript and PDF graphics into other vector formats, such as adobe illustrator, pdf, wm, swf and svg.
In Mac OS X terminal:
find . -name "*.eps" -exec pstopdf {} \;
This will search the current directory and all subdirectories for files matching *.eps (case sensitive, of course) and runs epstopdf on all results it finds. Try nam find for more information. Source
Linux includes the epstopdf utility.
David J.Moore’s solution:
EPS to PDF conversion is, for the average person a pain in the butt. A while back I wrote about how to easily convert your EPS files to PDF via terminal:
- Open terminal.app
- Navigate to the directory where the .eps files are located… use ‘cd’ followed by a folder or directory string to move to the folder ‘cd ..’ to move up a directory level and ‘ls’ to tell you what is in the directory your currently in.
- When you have located the files type the following:
epstopdf filename.eps- epstopdf will now convert that eps file to a pdf and place it in the same directory as:
filename.pdfWhilst that was an easier method that opening preview every time it is still time consuming. I have therefore written an Automator program to do it for you. The program will ask you to select all the EPS files you want to batch convert then it will batch convert them and put the PDF’s in the same folder as the EPS files (with the same file name). I have added the file to my server here.
An online service at Neevia Technology, called PDF converter. http://docupub.com/pdfconvert/ converts to and from eps, ps, pdf, and many bitmap formats.
