The ability to create a document, upload a document, search and find document files, edit, and then fax or email to anyone anywhere right from the convenience of your laptop anywhere in the world. All documents created are saved in your account for return access, and activities (fax, email and receipts for delivery) are also recorded and saved.

So far I have not discovered something I do not like. I have uploaded, created, searched for online documents to use, and both faxed and e-mailed documents without an issue.

Are you one that needs to easily sign documents and return by email? this is the software to use None I really liked how the software navigates you through the document so quickly so you don't forget to fill in any information, and it tells you if the recipient receives it. It's supposed to have just about any document you would need or want but I couldn't find any of the ones I needed. It was frustrating trying to look for a document and not be able to figure out where the list was.

THIS THING IS A DREAM (although I did have some kind of issue opening up a file.) I used the MERGE function and it merged some files I didn't need. That was weird. So I'm editing one page at a time instead. That seems to be working.

I would change the interface I would change the interface, to make it more friendly, the location of the buttons, and things like that, but the tool is very powerful and honestly very very helpful! Thanks a lot!

Convenience for all! It makes all our documents look professional. Imagine the combined functionalities of Word and Adobe put together into one software. This is what you get Uploading and downloading larger documents might take a while sometimes. What do you think about this review?

So far so good So far so good, I use Adobe Acrobat Pro DC at home and at work, I am still on my first day of my 30 day trial of PDFFILLER but I'm impressed so far. I particularly like the library and search features. More to come as my experience develops.
