PdfFiller is absolutely THE BEST! Beneficial and Convenient I was able to reregister my daughter for Prep. school. Only through PdfFiller I was able to email her to sign the form. She is in a whole other county. It would of taken me weeks to get all this done! I even able to find the custody form in another state. Most importantly I am able to handle my personal business, catch up on my work ALL in ONLY ONE Place! - *PdfFiller* Thank You for making my life easier. With appreciation and gratitude, A Loyal Fan - KJ

Helpful for Digital Signature Overall the PDF filler is amazing and free! These days, a lot of people don't have printers and scanners. Also, a lot of us are working from home. This software makes it possible to sign documents without printing and scanning. My least favorite thing is that you have to create an account to save your document. It would be nice to not have to provide my email to save the document.

creating forms for small private practice overall it is a good product once you are accustomed to operating within its rules and time lapse with commands and follow through ease of using current document to edit and create form it is slow to react to commands or does not recognize or follow commands first time you ask or click

I like everything except when filing in… I like everything except when filing in the forms the lines do not automatically wrap to the next line. I have to know to stop and manually go to the next line, Maybe that could be fixed. Also, when I tried to share the completed to form via email; nothing was received by the recipient. Only via fax did information get received.

I somehow allowed my subscription to renew, when I actually do not need this service. A quick contact with customer service handled the problem for me and I got a full refund. I was aided by a representative named ***. No hassle!

I like the signature feature that gives a lot of options. I wish there was a better way to add information and have it look nice, but it does have the flexibility to add something anywhere, so that is nice.
