initially the software did not allow me to transform document to pdf. contact customer support and eventually the software work as instructed. last the pdf filler content page will not allow the user to rotate the document to the correct form. the document had to be rescan to the proper orientation prior to changing out the format.

PDF Review
We use this program daily in our offices. It allows for ease of use in getting things signed and sent back quickly.
We have no cons at this time and have been using the services for almost 2 years now.

It's been a nice use-friendly experience overall. I like the way pdf found elsewhere could be easily pulled into (uploaded) the program without a glitch. And I really that all my documents are saved into the same system even those docs complete a few years back. I was pleasantly surprised. I would like to continue learning more about all the features your platform is offering. Especially the signing and sending of docs to others. I sincerely sense these is going to be my 'go-to' platform for many of my pdf needs. I need to keep on top & keep up ;).

Twice a year I need to turn a pdf form into a fillable form. I don't need a subscription for such a minimal need. I wish there was truly a free way to do this without creating a trial subscription.
