What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I like it.. I just can't figure out if I can fill a docment and save it and go back and change it. I also don't like that it is challenging to get data squarely in the center of each square in form. Even if you try to do one square at time so you can manipulate, it connects them and then you can only use them as one field.

It works, almost a must have thing. But not everything is perfect, there are some limited options. But you will never get it perfect because it is not an original document.

It's been very good working with PDF Filler. Makes saving forms so much easier. I only have one complaint. When it comes to dates, I usually need to write it as year-month-day; but PDF Filler is already programmed as day-month-year so I have to keep on erasing dates and fill it out by hand, which is annoying.

Great software, some things are not intuitive You can edit documents, replace text, add fillable fields, etc. Great for documents that are used often and just need a few details changed. "Replace text" can be difficult to use. Also the process of saving a document is kind of clunky.

What an awesome product. We use accord forms so often in this office that it is nice to have help! We like that most accord forms we use are already available from the site, but more so than that, the fact that we can upload our own documents as well. When you have to generate 150 certificates for one client, all different, this program makes that process seamless. The site runs very well, have not had to deal with freezing issues or losing extensive work because it didn't save, the site always saves my work for me. We just couldn't be more happy with the service. There is not a lot that we do not like about the program, but one thing sticks out for sure. If one of my agents is logged on to the site and another agent logs in, the first agent will usually be kicked off. This was not really even an issue since the system always saved the agents work, and all of my agents will announce now that they are logging in.
