What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
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.

My printing is horrible. This allow me to fill out legal forms without having to do them over and over. I will say getting the cursor right where you needed it was difficult.

Best customer service ever
Best customer service ever! I accidentally signed for a year and it cost me an amount of money I can't afford (it doesn't seem much, but when your local currency is way behind USD, it greatly hurts your wallet). After reaching Rachel on pdfFiller's customer service team, they not only refunded me but also waived a month of free access. I couldn't be happier of using it! Recommending it to all my friends, from now on!
