I received some paperwork that needed to be signed and sent back to sender in a timely manner. PDFfiller was the only way I could do this. I had no access to a printer or fax machine. I'm trying to learn all of the use of the PDFfiller. I am currently trying to learn how to download some of my saved papers and sign them, then send them out. I forgot how I did it yesterday.

The platform is very good, it fulfills exactly what it promises, it is even compatible with the NVDA screen reader for people with visual limitations. Unfortunately there is no language version in PT-BR, and in some tool icons the NVDA screen reader does not read.

This has been my favorite pdf program of all time. I do not work I am a happy homemaker and have a special needs son and have a lot of documents to file and fill and fax for him. This is the best program. The price is a bit high for me but it's worth it at times when I need to do something that other pdf programs just can't do it.

What do you like best?
PDFiller is ultra-convenient and super-easy to use. It's in the cloud, so it's easy to access. And it has a vast array of features. Storage is a cinch, whether on your hard drive or in the cloud.
What do you dislike?
I can't think of much that I don't like about the program. There might be a more direct or seamless way to save documents to Google Drive, in terms of getting them straight into a particular folder instead of just onto the Drive, but that's a minor issue.
Recommendations to others considering the product:
Try it. You'll like it.
What problems are you solving with the product? What benefits have you realized?
PDFiller is a lifesaver when I'm editing contracts and related forms. The clarity of the input and the ability to maneuver the text around the document is a huge plus. Line-outs and erasures are a breeze, making for "cleaner," more legible documents.

Very easy to use I like that it notifies me when someone has completed the document. I also like how you can customize the fields between numbers and dates which makes it fool proof. Support is very quick to respond and helpful. I have been trying to set up a document to copy certain fields throughout so they do have to enter their "name" every time, but I have had trouble trying to figure it out.
