See for yourself by reading reviews on the most popular resources:
Great online pdf editor. Should have more features in personal level, a bit annoying to not be able to perform basic functions such as erasing sections of a document or deleting pages in a commercial, paid product. That is my only complaint though. Great software otherwise.

Extremely Easy interface. Gathering Signatures is the Best and being able to do so via a text link is ingenius. Would be a 5 star if you would just offer the discounted annual purchase price.

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.

I really appreciate how streamlined and… I really appreciate how streamlined and easy it is to fill out tax docs! Makes it so much more hassle free. My only issue is that it's a 100% free service, as I wish this was something the IRS did a long time ago.

This was just new to me so it has taken me a lot of time to navigate around to do what I needed to do. I'm sure with some use and training it will be very easy to use. I have accomplished filling in the form but I'm trying to see how to get the new file name to appear as a download on my computer, so this is what I'm working on now.

What do you like best? Pdf Filler is extremely user friendly. I love being able to easily add signatures to documents. What do you dislike? I don't like that you cannot combine documents. Recommendations to others considering the product: Add the ability to combine or add documents. What problems are you solving with the product? What benefits have you realized?
