I am not very computer savvy and I am learning as I go with this new MacPro, but so far it has been a very helpful tool and plenty of help explaining how.

PDFfiller is an awesome tool to have. It saved me a lot of time of writing information on forms. I like my forms to be neat and typed instead of handwriting.

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.

It's been a little bit slow and clunky and doesn't always do what I expect, but I managed to figure out a lot of features I need, and it works well for me, for the most part.

It has been a little difficult at times but I am computer illiterate so if I can do it or manage to figure it out I think it’s safe to say anyone’s name.

I needed to edit a pdf file that was very long with only few corrections so this program was great.
It was so easy to use...I especailly like the erase too and then the size too to make the correction look good.
nothing.. I liked the entire program. I thought the cost was a little high as I only needed the program for a few weeks and wont be needing it again. So a lower fee for a weekly or monthly use would be good and you may get more users that way too

We have had a service application on line for several years. People have been printing, handwriting the answers to our application and emailing it back. I just received back my first fillable application and I love it. It is legible and all the answers appear where they are supposed to no more writing up the side of the page because of the limited space for answering.

The program is easy
The program is easy. I use it to convert documents into templates and then I provide links with my fillable forms to my clients to complete and return. I highly recommend.
