What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
At first, I was disappointed by the service. We needed to fill out a rental application and have been very stressed. We found this website which seemed to be a dream come true. After having filled out all of the painstaking details, found that we had to pay to be able to fill out a document online. This was very frustrating. However, a customer service representative quickly resolved our issues. Thank you.

I needed this program badly, just in the time for distance learning because of the Corona Virus. It was easy to navigate through and use. My only wish is that I would have found this program years earlier! I will update my rating to include the student (recipient) experience of pdfFiller after they return their first homework assignment.

What do you like best?
PDFfiller actually has lots of online tools that can help with many general document editing tasks. We can convert PDF files to lot of different document formats such as DOC files, which are files I use often at work. For document signing, editing and adding fillable fields is not complicated. The toolbar has tools that are neatly laid out and easy to access. There are lots of click-and-drag features that make using PDFfiller comfortable, even with hours of editing. There are also helpful collaboration options that let internal staff communicate about document edits.
What do you dislike?
From an admin perspective, it's been a delight working with PDFfiller, but some people that receive our digital documents can sometimes have trouble accessing the files and knowing how to sign them.
Recommendations to others considering the product:
PDFfiller can be a valuable solution if you need to make lots of edits to PDF files and don't have a much experience with more advanced software like Adobe Acrobat. It seems to be designed for beginner users, but can also work for more expert document editors.
What problems are you solving with the product? What benefits have you realized?
Even though I know how to use various popular PDF and document editing software, I often turn to PDFfiller to allow for more intuitive editing features and its abilities to work with just about any PDF we load into it. It's a versatile editing solution that lets us quickly format our documents to our specifications.

I had some slight issues on my 1st… I had some slight issues on my 1st attempt as there were fields in different locations than a previous edition of this form, but easily was able to correct the overwriting of several fields. Worked beautifully on several previous (new) documents.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.
