See for yourself by reading reviews on the most popular resources:
Just started so not a lot of feedback yet. It would be nice to be able to review who I sent documents for e-signatures too, so that if I can determine whether or not I made a mistake and have to redo the whole document, or if I have to tell the client to look in their spam folder, or what. Thanks!

I have found that PDFfiller is very simple to use and offers quite the range of options. Matter of fact, to date, I have yet to figure out anything they don't offer that I would ask to be added. Quite a happy client!

Easy And Fast PDF Form Filling Software! Works with all types of devices, so I can prepare a document for signature quick and right where I am. Pricing is very fair. It is sometimes a little slow and there is a bit of a learning curve but once those are overcome, it is practically flawless.

Extremely Useful, Slightly Non-Intuitive Love the program/service/software and all its online functions, including the US Legal Forms integration for documents like wills and trusts. But it is a little clunky/non-intuitive in terms of user experience and interaction–be prepared to spend time clicking around to find not only your own documents, but also the service's libraries. Looking forward to integrating with third-party/external cloud storage.

Much easier to use than Adobe and hours… Much easier to use than Adobe and hours of frustration. I tried pdfFiller for my business and within a few minutes .had a PDF fillable PDF created.

Tons of functionality for a great price. Excellent customer response time. Feedback: when using the "home"/"end" keyboard buttons, it immediately takes you to the top/bottom of the form instead of beginning/end of the text box you are editing. Just an unintuitive and weird feature. Also, it would be great if there was a way to save LinkToFill settings so that they can be applied across other documents. Overall really happy with this product!

Just plain user-friendly Very intuitive UX. Just easy to use that I don't even have to think about it. Normally I can see negatives with a product. Not this time however. Works great.
