The form I filled in was for a Medal of Honor recommendation for a Vietnam vet. The format and help with the form was clear and efficient. I had to come back and modify it, and everything was smooth and easy.Thanks for a very professional tool.

I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.

The card reading company kept declining every card I had even though they were all in good standing. Customer Service (online chat) tried several remedies. Still did not work. I needed to print the document I completed. Customer Service gave me a one time free print so I was not in a bind and will try again tomorrow from different computer to actually purchase the service!!Thank you!!

Perfect for merging multiple JPG images into a compact PDF
This app / web page allowed me to easily merge six JPG image files (each 2550x3300 pixels, some included photos) into a single compressed PDF document that was small enough (7MB) to be easily shared as an email attachment. Did exactly the job I wanted it to!

PDF documents are graphs of SDF objects. SDF objects can represent document components such as bookmarks, pages, fonts, and annotations, and so on. PDF is not the only document format built on top of SDF/COS. FDF (Form Data Format) and PJTF (Portable Job Ticket Format) are also built on top of SDF/COS.
