This has been a fun learning experience… This has been a fun learning experience with so many options that I didn't know existed...and so easy. Thank you PDFfiller for making life easier (and thanks to Anna too, who I had an instant helpful Chat with).

pdfFiller has wonderful support. You can email them or use a chat feature. From the chat feature, I was able to do a remote session through zoom to get my issues resolved quickly. Through email they always respond within 20 minutes. Great customer service!

Actual Customer Support I sent a question in via their form, and honestly expected a "word search" systemic response. Not only did I get a issue-specific response, the corrective actions were clear and documented with screen shots, making it easy for me to correct my mistake and move forward.

What do you like best? Easy to use! I don't do tech well, and this is easy! What do you dislike? I'd like to be able to easily add links that are active. What problems are you solving with the product? What benefits have you realized? PDF FILLER gives me the ability to secure my documents and files that I share with clients. I no longer have to worry that people are going to just steal my content and use as their own.
