I was happy to know I could use a blank form to enter my new figures when I had to file an amended form for both the Federal and State Taxes for 2014. Thank you.

I had trouble with saving files but I figured it out. The program comes with alot of different features and a webinar to see how it all works would be great.

Makes work so much easier
It makes my life so much easier
As a credentialing manager I am constantly filling out paper work. This application makes it so much easier for me. Instead of downloading forms, filling them out and then re scanning to send forms, I just use PDFfiller.
I don't really have a con for this application

My experience with PDFfiller has been nothing but win after win! At first i was worried i wasn't going to be able to sign without the help of a third party app, but, wouldn't you know? You guys have the option, and many other feats that helped me in the elaboration of mah necessary edit. Many thanks!

i was not happy with the Basic Plan being advertised for $8 per month and then subscribing and it suddenly being $20. I looked at some past notes from Sept. 2020 in my computer and it looks like I joined in Sept. 2020 and discovered the pricing being different than advertised, and I canceled then. Today I needed to sign some project documents and rejoined rather than playing around with a free trial of DocuSign that didn't offer what I wanted for variety in signatures etc. Giving PDF Filler a try. Will call CS to hear what their explanation is regarding what you advertise for $8 per month, only to see it is really $20. Evelyn Basile, Chicago

Using the app has been pretty easy so far
Using the app has been pretty straight forward and intuitive. Getting used to how to edit a PDF to get consistent results. Has been a big help. Users always want a free solution and I'm still testing the 30 day trial but maybe if you want the right solution it needs to be a paid solution.

It is a very satisfying
It is a very satisfying, professional software to edit pdf files. In almost no time managed to edit a long pdf document which saved us a lot of time.

The Quarantine Helper...
It has worked perfectly great in this time of need in which everything is been done from home. An excellent assistance to work from home.

Very easy to use
Very easy to use. Loved it. Struggled with editing sideways orientated text. Type replaced went a little wonky, it was for a quick edit to a a basic document, not an official presentation, in which case I might have required a more powerful editor.
