What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I found this by accident trying to find a 1500 free medical form but wasn't looking forward to filling it out by hand. We are a dental office just starting to use medical coding for new procedures. Plus I'd like to put our new patient forms on our website for patients to fill in electronically! Thank you!

It'd be helpful if there was a visual display on the side when selecting a document, so that I could see what I'm looking at and have the ability to rename it without completely opening it.

I found this site by using Google. I then had a few questions that were resolved by chatting with an agent. The agent gave me a 3 day free trial. I was able to do what I needed and purchased a subscription.

Software was user friendly. Ocassionally experienced frozen screen and saved information provided did not save properly, therefore, had to repeat the process.

The outputs of the system are great ... just your opening page is a bit confusing. I just wanted to look convert a document but couldn't see conversion icons - finally worked out that I have to use Add New button - remember people are coming to your website from other portals they have used before - and like me they look for a document conversion tool!

It is the best PDF to Word conversion I have ever seen. The resulting Word doc was able to be compared with another PDF conversion, giving me a near perfect comparison. This is what I was after and PDFfillre delivered.

It served my purposes It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes. It's a good tool.

What do you like best? I love the whiteout option and the text box. Also the drag option to move all text over. What do you dislike? I have no complaints at this time. Have had no issues since we first started using PDFiller. Recommendations to others considering the product: Purchase it What problems are you solving with the product? What benefits have you realized? I am whiting out personal information, Printing documents with additional text not on it to avoid printing more than necessary.
