pdfFiller scores top ratings on review platforms
I like it- does what it says- easy to fill in a form. My local authorities keep changing their forms so everytime we spend a long time converting them to word files for editing, they become obsolete! Now, we just work with this weeks form and it doesn't matter if they change the layout! Perfect- no more time wasting with forms!

Good company with a great product
This is a good company with a great product. I am a retired attorney who was in need of a certification of trust for our family living trust. I checked pdfFiller and found what I needed but then realized that in my experience as a lawyer, I already knew the basics of what had to be done. So I cancelled the subscription and within minutes, received word from pdfFiller that the subscription would be cancelled. An honest company that is responsive, with good products - can't do better than that.
Amending the future
The software is designed to edit PDFs. Makes updating documents and personal files very easy.
I wouldn't change anything for this product.
Great but just too expensive
Great but just too expensive. Especially considering we are already subscribed to so many other SaaS, this feels over priced.
Spelling assistance
The spelling check assistance is not very effective. It is difficult to predict where the cursor must be placed for the correction suggestions to pop up.
