I am glad to have this service available. The use is a little awkward ... hard to navigate between pages. Wish it was easier. I do like the ease of accessing and saving documents from the website to my computer.

The conversion from Pdf to word was the smoothest I've seen. There are very few errors. AMAZING! After reviewing the document I noticed that the conversion dropped the letter F. If there were two f's in a word the conversion dropped one of them.

What do you like best? pdfFiller is user-friendly. Creating templates and editing forms is a breeze. Blacking out HIPPA information is quick and easy. Customer Service is prompt and courteous. They resolved my issues quickly and efficiently. Our corporate office just opened another account, and everyone loves it. What do you dislike? I don't have any complaints. pdfFiller has everything I need to make my tasks more manageable. What problems are you solving with the product? What benefits have you realized? Completing required medical forms is faster and easier than ever before. Blacking out HIPAA information on EOB's has cut our time in half for claim submissions.

Auto Renewal Charge I was auto charged for a 2nd year for this service via PayPal. I do not need it and was surprised to see the charge. I contacted customer service via chat and they immediately issued a refund with no questions asked. I received an immediate email confirmation. That is customer service. Thank you pdfFiller.

I had an issue with the automatic renewal of my subscription smack in the middle of the COVID-19 pandemic. I have already been in quarantine for the past 4 weeks and cannot use the services of PDFfiller. I got in touch with the company and I immediately received a response from Anna who refunded the draft and cancelled my subscription. Because of the swift attention paid to my concerns, and the professional way in which it was handled, PDFfiller has earned my endorsement. *******
