This has been a great service for me! As an independent consultant, I often have to forward W9s to organizations. It is great to know I have a secure way to do that.

Much better than last year. But the pages slide badly -- need one page at a time to finish rather than slipping from page to page as I try to work on just one.

PDF Filler has been extremely easy to use and navigate. It has all the features that I need to fill out pdf forms. I've been using the service for over a year now and have never had any complaints.

it was nice but costly i can easily edit pdf files what i like the most about this software is that it is flexible and there's a lot of things you can do with the pdf file with this what i like the least about this software is that it not free, compared to other existing pdf editor, its an disadvantage as i might say

This software has solved many problems for a few clients, well done. Being able to host the forms online for anyone to fill out, which is something that I couldn't find with any other software. No way to remove the flow of fields, you are just able to move the order around, which is very annoying as well.

I mistakenly did not cancel the trial… I mistakenly did not cancel the trial period and was billed for a year's subscription. When I wrote to the support team, they immediately cancelled the subscription with a full refund. Even though the mistake had been mine, there was no lengthy questioning about how it happened or extra surcharges or the like. I very much appreciated their professionalism in meeting my needs.

What do you like best? The editing module is effortless! The tools available allow us to edit, rearrange and create whatever final version we want. It's very easy to use and makes editing quick. Time is so important and PDF Filler allows us to focus on the work that matters vs. spending countless hours editing documents. What do you dislike? I would like to have a media or image folder that we can get to without being in edit mode. Connecting team members is not easy and not straightforward - it would be great to have more control over this. What problems is the product solving and how is that benefiting you? PDF filler replaced Adobe. Adobe had so many glitches and didn't allow us to edit all documents. Now, PDF Filler gives us the ability to get our work done and quickly!

I liked the idea that I can modify a… I liked the idea that I can modify a document with ease, but the yearly rate for educators is too much. I probably would have continued if I was given a reasonable monthly option. I do have a few subscriptions that I keep on a monthly option. So, keep that on mind when you are working with teachers.
