PDF Filler as tool for Securing PDF files Very useful, convenient and very easy to use. A great tool for businesses. I like PDF filler the most when I would like to encrypt and decrypt documents, merge PDF files, crop or rotate PDF pages. I actually like PDF filler and there is nothing that I do not like in this software. It helped me big time with my PDF documents organization.

Thank you for providing a quick easy… Thank you for providing a quick easy and accessible way of editing pdf files that have permissions blocking from editing the file itself

So helpful. I can fill out the form instead of scanning, printing, filling out, and then scanning again so that I can send it back. I did try other programs... this one is by far the very best.

Great tool! Great tool. I used it only to edit like half a dozen infographics. If anything I would ask for a full color pallet and different shapes for fills and graphics. It could maybe use a little more simplicity of use with the saving/ uploading function but at least functionality is there, no bugs in my experience.

Top notch company to work with. Software was easy to use, and they were fast to respond with customer support. Definitely will use in the future if I have more needs to use this type of software.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

What do you like best? I like how simple it is to navigate fields. The program is really good about identifying editable fields in all documents. What do you dislike? I think they can improve the downloading/saving function. There seem to be more steps than one would expect. Recommendations to others considering the product: If you are looking for software that is simple and allows you to edit PDF files easily, this is your program. I feel the least amount of pain when renewing my subscription. For me, it is a must-have tool. What problems are you solving with the product? What benefits have you realized? Zero lag time in legal documents or any documents that require redlining, editing, etc.

Great service. I thought my subscription had expired but the tech support hooked me back up in a jiffy! I prefer to use PDFfiller program rather than the Acrobat Reader DC program. I will always renew my subscription in the future.
