I LOVE this program! I find it extremely beneficial when completing scholarships that are in PDF form. The forms are neat, legible and professional looking.

This app has been a lifesaver. I have recently started a position as an Administrative Assistant and the abilities within this program make my job hassle-free. It makes filling in PDFs and requesting e-signatures as efficient as possible.

Great for .pdf that You Need to Edit-PDFfiller is the way to Go!
Great for doing 1099s at tax time!
Wonderful for use with prefab downloadable boilerplate documents
that you purchase from the web.
Great storage for being able to go back in and repurpose a saved document for an additional use.
Print alignment not always spot on for forms, such as 1099s and you have to play with settings a bit,
but overall not too cumbersome.

I love the PDF Filler. The only thing I don't like is the fact that when editing the font changes from the original font on the form that I am trying to edit.

Convenience for all!
It makes all our documents look professional. Imagine the combined functionalities of Word and Adobe put together into one software. This is what you get
Uploading and downloading larger documents might take a while sometimes.

great site has helped me out a lot being a successor for my deceased loved one. thanks for the great site but please fix the type or a form. it looks terrible and clears the background
2021-01-06
Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.
