1) Start with Zamzar, which not not only converts documents  to PDF, but also images formats, documents, music, videos and other format (tar, zip …) the list is very complete, and you will receive the document by email. The commercial version is for large users. Sometimes the conversion is slow and one have to be patient to receive the email containing the link to the converterd document.

2) pdfonfly “converts html to PDF” I ‘ve tried with my blog and it worked fine .You don’t need to give away your email address, the conveted PDF document can be downloaded directly through the site

3) Expresspdf offers three types of conversion (html, doc, xls to pdf) with an option A3,  For this service you must provide your email

4) Createpdf.adobe.com from the Adobe website, offers 5 free conversions. If you have an important document to convert, I think this would be the right place to do  so.

5) Brand new and also available in spanish : guardarcomopdf very simple, (available conversions . doc. xls. ppt.jpg. rtf. txt), as Zamzar you must give your email to be able de receive  a link to  the document to download . This service is new, conversion is quick. The graphical interface of this site is very nice.

6 ) rss2pdf.com as its name suggests, converts rss in pdf . But during the test, the conversion does not include neither picutres (options unavailable at the moment) nor tables.

7) doc2pdf.net converts to .rtf .ppt .xls .doc. This site is simple, and the result is generated directly on the site without the need to give away your email. Conversion is fast.

PDF converter allows conversions in both directions (as zamzar) Freepdfconvert has a feature that provides  a  java script to embbed on your site .

9) Google doc also have a PDF conveter. You have to sign up for a gmail account to be able to do the conversion. This to my taste, is the easiest way to convert document to PDF one you use google doc as your day to day text editor.
