What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Though perhaps a bit expensive, PDFfiller.com is extremely well-designed, feature-rich and easy to use. While I have no complaints about the basic product, I was bothered by design feature that seemed to insist that I enroll in a more expensive tier of service without giving me the chance to opt out or cancel. Any popup page that requires a user to select - and pay for! - a more expensive service level should always include "close" and "cancel" options. While I'm still a bit troubled by this aspect of PDFfiller's site design, when I raised the issue with your support staff, Ellilou Ilano quickly responded and helped resolve my problem.

this makes filling out medical forms sooo much easier. I can fill them out and email them back without needing to print them and rescan or fax them back. Thank you for this wonderful software ! So this being a followup review I can tell you I still love it as much as I did before. I was able to use it to fill out medical forms and also a form for a winter retreat. The only drawback to this PDFfiller.com is the cost.

What do you like best?
The best feature of PDFFiller is its ease of use, whether it's editing documents, signing documents, and then being able to access your documents anywhere by logging onto the site, as opposed to being constrained if you don't have your computer files with you.
What do you dislike?
Some of the option menus should be improved upon, especially as far as layout and ease of finding what you need, it's a bit counterintuitive though with experience that becomes less of an issue.
What problems are you solving with the product? What benefits have you realized?
Signing PDFs with ease. Being able to access and edit a pdf no matter where I am as long as I have internet access, even if I don't have my computer with me and/or don't have access to my cloud storage.

It was easy to sign and save... It was easy to sign and save my document with no interruptions or gemecs in between. I thought it would of been hard to get it sent via email but that was even more of a breeze.

So far so good So far so good, I would have given it a 5, if downloading my edited documents weren't hidden behind a paywall, but hey, I get it, it is in our nature to capitalize on things where it is impossible to find a solution, few have the solution, so why give it away for free? But yeah, good software none the less.

Also, it is intuitive I have limited computer experience and only once had to contact learner support and than they could not have been more helpful. Thank you.
