Omnivorous Surfer

I've tried others, but this site really works! Just upload your PDF file to pdftoword.com and you'll receive by email your file converted to a .DOC or .RTF file. The file I tried was fairly large (50+pages) and contained a graphic and several tables. Worked like a charm!

Zamzar does free online file conversion for files up to 100 MB. Upload the file and you will be sent an email link to the converted file. Several file types (document, image, music, video, and compressed) can be converted. You can sign up for an account (3 types available) which will allow conversion of larger files.
