Used PDF filler to help with guardianship papers for our grandson. Paid over $500 for help in 2010. PDF filler saved money and most important, time by being able to fill them at home and not the legal library.

Intuitive and easy to use Easily and quickly fill pdfs with this simple software, just be aware there is no free option other than a 30-day trial. This software is really straightforward and easy to use. I find it intuitive and am able to edit pdfs quickly and painlessly. Adding a signature is really easy as well. I did the free trial of this software and even though I was impressed, I didn't end up purchasing the monthly subscription due to my needs. There are options out there that are free, although they're definitely inferior in terms of functionality and user interface. So I think the cost (even though it is reasonable) ended up being not worth it for me specifically in the end. Other than that, I had no problems with the software and would recommend it to someone who uses pdf software frequently.

What do you like best? Seamless conversion of files to various file formats. What do you dislike? Lag between switching to different parts of the interface and saving files disrupts the user experience. What problems are you solving with the product? What benefits have you realized? Easy to fill out PDF files. Easy to convert image files to required formats. Safe storage of sensitive personal information in one location.
