What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I've had problems expanding boxes to fit text in. Customer support sent a YouTube video and that was some help and fixed one box, but then I had problems with a second box and just didn't have the time to keep trying to fix the problem.
After a few attempts I was able to fix the problem, and now I am very impressed with the program.

Very helpful for filling out international documents in Japanese. Typing in Japanese alphabet was not good but the copy and paste approach worked just fine!

A must have!!
This is a must have for anyone that uses PDF's alot. It can save you a ton of time.
This software is awesome, I love that you can take any PDF and alter it. It is easy to use and comes in handy.
I wish this software was more set up like Word, as in the features and where things are located. Some of the features are hard to find.

PDFfiller is great if you need to edit/change PDFs
This software allows us to fill out and share PDFs, vastly cutting down on our printing/scanning song and dance.
No real negatives other than I wish it were free.

I think their customer service is excellent and very responsive. I was intimidated by the website but that is a reflection on my limited tolerance to "figure it out".
