What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I've only used it a few times, but I think that I might be using it more over the next couple of years, as my daughter finishes high school and goes through the college application process! She's also on a couple of sports teams which require the same forms every year; it will be nice to have the info already entered and just modify some dates!

Great service! Could use some updates though. The site is rather slow at times, and when changes text size there seems to be a bug where the page needs to refresh or reload. Also, general improvements on loading time would be nice. Also, please make the process of saving to PDF less steps and less clunky. I don't need to be shown where the pdf will be once downloaded.

Surprised I had signed up for a year
It worked as I expected. Only needed it to print once but ended up using it twice. Not sure when I will need it again
Not sure if I can cancel or if it is automatically renewed. May never use again so I hope I will get a message that I can continue or decline.

Wish I Could Change Color of Signature

Payment issue dealt with swiftly
After both my cards being declined to register my subscription, I went onto the online support chat. Kara was super helpful and quick to deal with my issue - very professional and friendly. Kara was very generous in giving me three free days and advised within that time to try my payment again after 24 hours. Thank you Kara for taking the stress away and resolving my issue fast. Morven

What do you like best?
We have used PDFFiller for years. I like the ability to use editing tools other apps charge extra for. The ability to use the mobile app was especially useful when we were in a bidding war for the purchase of our home. We were able to edit and sign purchase agreement on the fly.
What do you dislike?
User interface has not been updated in a while and feels a little clunky.
What problems are you solving with the product? What benefits have you realized?
We have clients sign documents and contracts. We are able to edit PDFs directly rather than scanning or retyping documents in a word prove easier.

Support is good but last release is bad
I am really fond of their support team. They are very friendly and provide all help the can. But that's not enough for good product. Support can't fix bugs or make it good for tablets. Try harder.
