I am so new to this, I need more time to create a useful review! I'm really excited about the application and if it fits my needs I'm happy to share with others. I know in the school district they are always looking for useful tools.

You need t tell people that if they enter numbers with commas, the IRS filing process does not work. After lots of time and trial/error, I stumbled across that as the cause of my problems.

Great for my online classes!
This has been a great tool for editing PDFs for my Anatomy class. The only problem is the "drawing" tool does not provide enough color options. It's very limited.

Excellent website with great features
I receive documents from my client's customers that need to be filled out and signed by my client. These are handled by PDFFILLER quickly and efficiently.
It's very easy to fill in PDF files and it's just as simple to add and insert signatures.
Sometimes movements within the website are a bit lengthy. After downloading a completed document, returning to the exact page would be nice.
