pdfFiller scores top ratings on review platforms
Obviously, the sales portion of the Web site needs clarifying, but customer support could not have been more generous and quick in solving my misunderstanding. Wish all companies did as fine a job.
The website said there will be no charge for 30 days but my card got charged 1 dollar. This is clear misleading attitude. I did not find half a star to give.
My Favorite PDF Signing Software
I've been using PdfFiller for many years and I've gotten used to the interface and so to me, it's pretty easy to use, but I've dabbled with other online document signing software and I admit those are pretty easy to use.
Some of its competitors seems to have pretty user friendly interfaces.
Very interesting and helpful as I needed this to hopefully obtain a Passport. My original Certificate is barely readable. Thank you so much, Judith Mann
Anna was very helpful in resolving my billing issue
Anna was very helpful in resolving billing issue. She was immediately responsive to my inquiry and I will definitely recommend PDF Filler friends and colleagues! Thank you very much.
Handy service. Swift support. I am amazed
Let me share with you my experience frankly. I needed to edit a one single pdf document. Found this service. Registered for a free trial. Edited the document swiftly and smoothly. And forgot about it. Till the moment I received a charge for the yearly subscription. Which, admittedly, is not low at all (though may be reasonable to those who use this service).Anyway, I contacted pdfFiller support team, and I was surprised by both: 1) the fact that they immediately agreed to issue a refund, as it met their policy (I canceled in less than 24 hours, actually, immediately) 2) that even though they told that I will receive the money back within 1-5 business days - I got it within a few minutes. I am perplexed. The only pity really is that I can't afford it
