I am just learning about this program. So far it is easy and appears secure. I have initially been using the redaction/ blackout feature for several PDF files that I am sending to a client and it has been very effective. I am impressed with the "save" feature in that it allows you to save the edited file in a different format, I.e. Word.

Some of the fill ins didn't exactly fill in right, but this was my first time using PDF Filler, so maybe it is just part of the learning curve for me. Thanks.

What do you like best?
That I am able to take any non-fillable pdf document and make it fillable.
What do you dislike?
I find the ease of use of the website decreased with the updated version. Not impossible, but less ease of use. Nothing too bad.
What problems are you solving with the product? What benefits have you realized?
I use pdfiller in all aspects of my job where non-fillable documents are not available. From Business Management to Human Resources.

Very easy to use That I could fill it in immediately and be able to upload it and save it somewhere else. Also that the formatting remained the same That I had to save it twice in order to get what I had wrote. I also hate that the text box does not stay within the area you type in.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL

There are some glitches There are some glitches, like if you type to fast it will double or triple the word your typing. But other than that it's great.
