What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
So far so good. The only thing I was confused on was that I was able to edit a document before actually registering. Then, finding out later, I could not even print the document without registering. I am not complaining, I was just confused. I am a senior !!

Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

Great service. There isn't anything that I can't do with this program. Very convenient. It works when you need it. My only desire is that while typing, the sentences should automatically loop to the next line. It's bothersome that I have to keep my eyes on the line instead of what I'm doing.

What do you like best?
Being able to type into a form that would otherwise be hard to complete.
What do you dislike?
Once document is finished, it is always like a Easter egg hunt to find its saved location on my PC. Should be in downloads folder, but guess again!
What problems are you solving with the product? What benefits have you realized?
PDF filler allows one to complete a complicated form in legible printed characters. This makes a very good impression with clients, banks and other recipients of the finished document.

Wish I Could Change Color of Signature I enjoyed this tool and site. However, I wish there was just some way that I could not only change the font for my signature but the color to blue as well.

I've been using Pdffiller for several… I've been using Pdffiller for several years now and couldn't have asked for anything more from this company. I recently upgraded my account to premium for even more services. I'll be around with this company for many more years!

listen I appreciate your services and recommend it to anyone based on their ability to process a financial authorization and so I didn't want PDF-filler to be discouraged but I'm sensitive to express I have to revisit your advisory environment some time after the year is up!
