This is a really good program this allows me to upload PDF Forms that have auto fill and I can now save them for records I recommend this to anyone filling out ATF forms
I like that I can erase parts and add text of size and font that I like and move it around so it's where I want it. When I erase part it doesn't cause the rest of the document to move around. It stays put. That is essential when I am editing a document with a puzzle at the bottom.
Made my life easier by not having to go sign in person. Works very well. I love it
