I took away one star because this is not an intuitive program at all. I have spent hours trying to figure out very simple tasks but once I figured it out it everything went very smothly.

I really liked the entire PDF Filler platform! The content was laid out clearly and it was really easy to get started (even when I was frazzled about other things). Working with the platform in seamless and I have already recommended it to my mom who uses PDFs in her company 24/7

What do you like best?
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.
What do you dislike?
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.
What problems are you solving with the product? What benefits have you realized?
Can work and send from home, work, on the road. No need to hunt for a fax service / company; no need to leave where I am at to go fax a document; can work and send documents in the middle of the night right from home or while on the road; have been able to search and find online documents and upload into account for editing use; easy to share documents via PDFiller; you can send documents to anyone with an e-mail address - your recipient does not need to leave their laptop either!

What do you like best?
The upside is that it's very efficient and expedites completing forms effectively. I have used other software and didn't find them to be easy to navigate or efficient.
What do you dislike?
The downside is that sometimes the text doesn't align when filling in forms I have to complete from other service industries. Also, when PDFfiller is the default PDF it does not print without having to refresh several times.
Recommendations to others considering the product:
This software is really good and does make my administrative work easier and less tedious. There are some quirks but when I have experienced them, the support received was expedient and exceeded my expectations.
What problems are you solving with the product? What benefits have you realized?
It has really helped me to complete the necessary documents in a timely manner when there are no glitches. I love the easy access to my documents when completed.

The best online utility for word processing of any type available. The best online resource for anything that deals with words. Has every feature imaginable, and then some, to get personal or professional work done fast. I have caused myself alot of grief and wasted valuable time looking for a better or cheaper app and I feel as if I have tried them all. pdf Filler has it all and will be the only app you will ever need. From converting files to sending out your daily mail. This app does it all and it is simple, clear and concise!

Excellent service. Website is easy to navigate and the forms available are excellent. In my case, even though the website is user friendly, I think a short webinar to familiarize customers would be of great benefit. I would certainly recommend PDFiler to others.

I've been using different apps for… I've been using different apps for years that take me about 15-30 minutes to change one document but with PDFfiller it took me less than two minutes! so worth the yearly fee.

the feature of editing pdf file and the digital signature generation and its use plus the option for downloading the edited file has been of great help for me.
