I just released online-pdf.org.
It is a 100% free online tool to create PDF file, made in my spare time.

It supports PDF files, image files like JPG and office documents like Word, Excel and Powerpoint presentations.

Upload them, merge them, make page selections, add filters, use the options available.
And you will get a true PDF file in the format and design you choose.

No software needed :)

Hope you like my approach of web 2.0 PDF creation software.
Heavily dependant on node forms, entity fields and dependant fields.

Enjoy!
