pdfFiller scores top ratings on review platforms
It has made work much easier. In the legal field we deal with a ridiculous amount of documents. Many IRS and government forms require some PDF filler, Adobe Acrobat does not do the job PDF filler can. To be able to access my docs from anywhere is amazing. The email, sign, fax, and all the other features make it actually fun.
Got up & running pretty quickly. Very grateful. Really appreciated the Guidebook!!! Running in to a few glitches, but I have confidence that there are solutions as the software seems pretty powerful.
I genuinely love this program
I genuinely love this program. I don't have to wait for anyone else to print things for me and then get backed up on my work. I can just create what I need and send it right then. Super simple and user friendly.
Excellent Product
Excellent. It has been super useful in my practice.
This is very easy to use. I like the drag/drop feature.
I wish you could do drag/drop for pictures.
Interesting product the pdfFiller. I would like to learn what else I can do with this software. The new look for the PDF is wonderful but I don't know if I would be able to use the old PDF from Microsoft. It seems I just paid my Microsoft subscription. It seems that the PDF is a software of it's own and doesn't come with the Microsoft Tools.
I large amount of relevant templates, especially the collection of tax and business documents.
After searching all over for a form builder, a template library, and a document signing tool, it was so satisfying to stumble across a site that can be all three, do it well, and even be affordable to use!
