I have PDF files with form fields that can be filled out. However, if
you just have Adobe Acrobat Reader, you can not fill out the forms and
save the results locally.

I want to distribute my PDF files to a lot of users, and do not want
to ask them to have to install a third-party application in order to
save their completed form.

Is there a software application that would allow me to create PDFs
with forms that users could save locally without have to install extra
software locally? How much is it (approx)?

Would you be against using a print driver?  Or you could use server
side software to send a request to generate a pdf with a click of a
button on a web page and generate the pdf on the fly (and you could
prompt the user to save locally).  If that's what you're looking for I
could be more specific.  The cost would depend on the amount of data
you're trying to process and the expected response times.

Hello Webravi,
We have an existing set of PDFs (about 90 pages total) that have form
fields. We would be open to converting them to html, then having them
converted back to PDF on the fly, if that's what you mean. We're open
to almost anything, as long as the user doesn't need to install
software.
Thanks,
James

Several government agencies that I know provide PDFs that are
printable and for users who wish to enter data electronically, they
provide the same files in  RTF or DOC formats.  There are a number of
services that do the conversion:

Thanks ominvorous. The problem with those, however, is that the uers
cannot save the data they have entered locally using just Acrobat
Reader....

Adobe sells a product which can be used to add saving rights to PDFs
so they could be saved by an Acrobat Reader. It's pretty expensive:

Other solutions could include setting up a server which will store
user's modifications obtained by PDF submit and displying them back to
users.
