What do you like best?
The program is user friendly and helps me with the essential tools I need to fill in and change my PDF files. I use this on a daily basis for work and works very well with other programs I use.
What do you dislike?
The font match is the only downside of the program i face especial when I have to fill in words and characters onto the document. It takes time for to match the font that is similar to the original font. Collating pages in a certain order is difficult for me but I decided not to use this feature.
What problems are you solving with the product? What benefits have you realized?
I am facing no problems using the program. The main benefit I use this program is the editing of the documents revived for out business to use for our needs.

What do you like best? PDF Filler helped me when I inherited a bunch of learning material that referenced outdated case studies and I needed to update for class. Because I didn't have Adobe or photoshop, this was a great alternative to help me quickly update the decks. Erase text allowed me to "white out" the outdated information without compromising design quality. What do you dislike? If you are adding text and trying to use text box, it will show a box around what you replace. When using the text feature to replace text, of course, you won't have an exact match unless you know the current document's font and size. Nonetheless, PDF Filler makes it easy to drag, drop and align so that you'd have to really stare at the document to notice the differences between the original text and your replacement text. What problems are you solving with the product? What benefits have you realized? Needing to edit PDF's that were previously created, and provided no access to the original version. Better ease of use//less learning curve than Photoshop. Cost-friendly alternative to Adobe.
