Which formats do you want to convert? And which formats should be the result?

Appended is an excerpt from the Image Compression FAQ. It is a library though and you will probably have to do some programming before it does everything you need.

Does this help?

Free, portable C code for JPEG compression is available from the Independent
JPEG Group.  Source code, documentation, and test files are included.
Version 5b is available from ftp.uu.net:/graphics/jpeg/jpegsrc.v5b.tar.gz.
If you are on a PC you may prefer ZIP archive format, which you can find at
oak.oakland.edu:/SimTel/msdos/graphics/jpgsrc5a.zip (or at any Simtel mirror
site).  On CompuServe, see the GRAPHSUPPORT forum (GO GRAPHSUP), library 12,
file jpgs5a.zip.

The IJG code includes a reusable JPEG compression/decompression library,
plus sample applications "cjpeg" and "djpeg", which perform conversion
between JPEG JFIF format and image files in PPM/PGM (PBMPLUS), GIF, BMP,
Utah RLE, and Targa formats.  Two small applications "wrjpgcom" and
"rdjpgcom" insert and extract textual comments in JFIF files.
The package is highly portable; it has been used successfully on many
machines ranging from Apple IIs to Crays.

The IJG code is free for both noncommercial and commercial use; only an
acknowledgement in your documentation is required to use it in a product.
(See the README file in the distribution for details.)

Just looked further: ImageMagick does what you want (without programming efforts) Look at  http://www.wizards.dupont.com/cristy/ImageMagick.html , this is what you need.
