What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Getting to put 3 people on the account has been great. All of the features are exactly what I needed, and the editor is easy to use. I was a little wary if it would be worth the money, but I'm very happy with my purchase.

What do you like best?
I can remove text with the delete button rather than having the use the eraser tool
What do you dislike?
If I delete all of the characters from a text box, I have to put a space for it to stick; I can't add or drag in other pdfs to merge them. I have to merge them using a separate tool.
Recommendations to others considering the product:
Inexpensive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Redacting resumes in PDF form. Easy to fill out forms as well as it recognizes what the form is asking.

What do you like best?
I like the fact that live Customer service is always there to guide you if there's a problem.
What do you dislike?
The only thing I dislike if when a large corporation wants a form filled out and you use PDF Filler they come back and tell you their shop uses Adobe Acrobat and to please fill out the form once again using Adobe.
Recommendations to others considering the product:
I'd recommend it

needed a PDF filler software easy to use easy to fill out lots of PDF forms without hassle Easy to use. Can save forms for future use. Does not require any extra learning. Intuitive format makes easy for anyone to use. Cost was a bit much, but decided the year membership was the best savings deal. Have used it multiple times already in the first few months so I am glad I did not do a month to month membership.
