I was sort of afraid to install and pay for this online. There is so much identity theft out there.. I was just a victim of fraud on my bank account. But this seem pretty secure and was easy to get going.

I'm learning more as I go along; it's more helpful. And I'm still learning! I have discovered that I can upload the legal documents I'm working on to PDFiller with many useful things.

The platform is very good, it fulfills exactly what it promises, it is even compatible with the NVDA screen reader for people with visual limitations. Unfortunately there is no language version in PT-BR, and in some tool icons the NVDA screen reader does not read.

Amazing service so far Amazing service so far. After the free document uploads I will strongly consider getting a plan. Very easy to use and straight forward.

Solid, provides the service you need Easy to use. Mostly used for inserting signatures. Sometimes the signature block format gets distorted (inserts as a code).
