What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I had a little issue trying to find out how to print the form. Also, the little movable box that kept showing me where to check got in the way of reading the document. I X'ed it out most of the time so I could read the instructions.

Good service. Can be a little difficult to line up the text in the correct spot. Would be good if you could easily move the text box up and down a little to line things up.

This is a tool which I never thought I would use so much! I love it! I think the dashboard is cluttered and not the easiest to navigate, and a "strike through" option for documents would be nice to have.

What do you like best?
PDFilller is so easy to use. I am "tech challenged" and I have no problems using this program.
What do you dislike?
That I can't upload more than one document at a time even though there is an option for uploading multiple documents and that whenever I print or save a document the program doesn't revert back automatically to my "inbox"...it's just a lot of clicking...too many steps to get from "a" to "b" sometimes.
Recommendations to others considering the product:
The price is right, it's easy to use, you won't be disappointed!
What problems are you solving with the product? What benefits have you realized?
PDFiller cuts down on the amount of time I have to spend creating documents.

Can you remember what all the lower…
Can you remember what all the lower case letters look like when you are filling out forms by hand. I didn't remember, but when you use PDF filler you it does it for you.

Tons of great features to streamline and especially for working with client signatures. Just discovered the document password protection, which is *******. Customer service is very efficient thru the chat.

It's been great, especially when it comes to using anything that has to do with technology, I'm a non Techie, it's been somewhat easy I'd say.Thanks so much

Cancelled my subscription within the 30 Trial Period and was charged the following month. Had an online chat and they issued a refund with no questions asked. Good Business!
