This is only my second time but I do like how easy it is to type directly on the file. Just waiting to make sure they received it on the other end. Thanks

This is my first time using PDF filler, but I like the ability to work with PDF documents this program has given me so far. I would really like the ability to highlight and possibly copy the PDF over to a word or excel document. But being able to highlight and put a sticky is excellent!!!

With this document I had to learn how to rotate the document which took an inquiry on the internet to find the instructions. Could not seem to open any help window for the instruction.

Editing pdfs without the need to convert them
What i like the most about this software is the fact that when i have to edit a pdf wher i lost my source document i dont have to convert it in order to edit it, i can just simply use pdf filler editing functions and that's it.
Took some getting used to as it, also in some cases is complicated to get the text in the place i selected to put it

Great Program to help buyer's get their electronically signed documents
It makes it much easier for the buyer to get documents that can be electronically signed.
Quality of the documents that get sent to my buyer's is fantastic. The look of the documents are professional quality
Ease of use. It is hard to remember how to set up the file to get to the buyer quickly. I always have to try it 2 different times to get it right.

Finally
I've tried for months to finish interrogatories needed to prepare for my lawsuit coming in July, finally, I found this the other day and printed out my discovery questions ready to serve opposing council

Combining two files was relatively easy once I read the How to Guide three times to figure it out. But editing text in the file resulted in a change in the font that was not particularly satisfying and could not be corrected.

Great software
Loved the ease of this software - it saves lots of time.
This software is so so easy to use and makes filling out forms then saving those forms so much easier.
I found no cons with the use of this software. It was so easy to use and eliminated filling out by hand.

I had an issue with the automatic renewal of my subscription smack in the middle of the COVID-19 pandemic. I have already been in quarantine for the past 4 weeks and cannot use the services of PDFfiller.
I got in touch with the company and I immediately received a response from Anna who refunded the draft and cancelled my subscription.
Because of the swift attention paid to my concerns, and the professional way in which it was handled, PDFfiller has earned my endorsement.
