With Zamzar, you can convert documents, eBooks, images, audio and video files for free. For instance, you can convert .eps files to .tiff or jpg files, .pdfs to .jpgs, and mp3 files to wav files, etc. Usually, you upload the file you want to convert and Zamzar emails you with a link to download the file once the conversion is done.
If you find you need to convert a lot of files (or really big files) on a regular basis, or if you want to store and manage files, you can sign up for a paid account (Basic accounts start at $9 per month).
This tool saved me a ton of time and hassle -- hope it does the same for you!
