Still getting used the program but like it a lot!
I love it -- it helped me fill in some VA medical forms and made them look very professional, plus I could go back and edit as needed. It also allows me to save, print, and email. There are many other features too!

Very easy to use
I am excited to learn all the features the software has to offer.
I am so happy i can take current PDF files and turn them into filliable files. This has been very helpful as i started this position and can't always find fillable files.

A good pdf editor, although there is still some work to do with the command consistency with the environment (windows keys, for instance while editing a document if we press home the screen goes to the header of the document).

Overall great value for the performance and features!
Great UI/UX, picks up all embedded objects from a multi-layer or flat PDF file. Reasonable subscription plan options and the signature/send to sign features are a game changer for a SaaS tool.

I was told by a lawyer that the cost of his writing a Consent Order would be $2000.00.
Instead, I used PdfFiller and it cost me $144 for a year's subscription with the same results.
Kind of a No Brainer.
Thank you PdfFiller.
