What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Excellent service, however, I would have liked to have known there was a fee prior to filling out the form. I just assumed it was a Royal Bank form as that is what I googled.

Nice service, but entering in text into some of the fields can result in wonky formatting if more text than can be displayed is entered. And it's not easy to re-visit the fields and edit/shorten the text.
2018-01-06
It can be great, but it's a little buggy at times. The signature feature often crashes the signer's device, whether mobile or desktop, and the API integration with Zapier is very finicky as well.

PDF Filler Signature function is great
PDF Filler is pretty good, the ability to edit pdf's is always good but I have found the Signature copy function particularly useful over the standard PDF tools.

I am able to send out docs for signing and convert from Word to PDf, would love to learn more!
Please contact me for classes- I want to understand the scope of opportunities that I am availed to.
Plus a few specific items like sending a cover letter with the doc.
Thanks so much!
