Great functionality, may need some better guidance on how to do various tasks from the very basic and simple (extract a single table into excel) to the most advanced

Makes creating and filling out forms a breeze! Overall, if you need to have PDF forms in your life, you couldn't ask for a better solution than this. I'm just waiting for the day when it the basic version isn't free anymore--let's hope it never comes! We live in the twenty-first century. So few things rankle me more than seeing someone's sent me a Word document and pretended it's a form. The same is true for people who send me PDFs and expect me to print and fill them out by hand. PDFfiller is the solution to all these problems and more. It makes the sending and receiving of forms so easy that even a kid could do it. I really have no complaints about PDFfiller. It does what it needs to do quickly and easily, and it didn't take me long to learn how to use it. Even things that once seemed formidable to me (for instance, the dreaded splitting and combining of PDFs) is easy with PDFfiller.

Intuitive and easy to use Easily and quickly fill pdfs with this simple software, just be aware there is no free option other than a 30-day trial. This software is really straightforward and easy to use. I find it intuitive and am able to edit pdfs quickly and painlessly. Adding a signature is really easy as well. I did the free trial of this software and even though I was impressed, I didn't end up purchasing the monthly subscription due to my needs. There are options out there that are free, although they're definitely inferior in terms of functionality and user interface. So I think the cost (even though it is reasonable) ended up being not worth it for me specifically in the end. Other than that, I had no problems with the software and would recommend it to someone who uses pdf software frequently.

What do you like best? The ability to upload documents as templates, to work on completed documents, whether changing page order or add/modify information. What do you dislike? I find it challenging to change fonts and text color. I'm not even sure it's possible. What problems are you solving with the product? What benefits have you realized? Simplification of creating clear, typed forms that elevate the professionalism of everythign we do.

What do you like best? User friendly. Can do anything I really need, from editing pdfs, splitting up and saving parts of documents, signed documents, etc. What do you dislike? The sign in page can be a bit wonky and hard to see if you're signed in. If you've been signed out and start uploading it puts you into the trial mode, and once you figure out whats going on you have to start over. What problems are you solving with the product? What benefits have you realized? Signing documents is really important for me, which is the biggest benefit. But the ability to edit and fill out pdf documents has been wonderful as well.
