Awesome, I love it,I am a disabled Veteran, retired from the Navy and working with the VA many PDFs are used, this makes it so simple and the ability to take a picture of your signature and use it on document is great!

Streamline document management with real ease. We use this tool for document management mainly and it does the job with ease. Document upload is real quick Mobile applications work really good. Edit or add content to your PDF file, I love this feature as it helps to add content whenever required before sending it to the customers. I don't see any disadvantage with this tool.

IT'S BETTER THAN DOCUSIGN I like that you can send to other to sign just like docusign. You can also fill in the blanks. You can share the info and even print. Also is not too pricey. What I don't like is, when I send to multiple signers anyone can sign even on my signature. I wish they'd allow set signatures per person so that folks won't get confused .

I'm computer illiterate and even I could easily use this It saved me time and money, thank you :) Easy to use and easy to understand format, it made me feel like a pro lol, and I love the feature of being able to download your copies to your computer in either a PDF or a Word file, personally I dislike PDF files but if you have to send or receive them this is the perfect tool to do it with. Have already recommended it to several friends and family.

PDF filler is VERY easy to use PDF filler is VERY easy to use. The only sticky point for me sometimes is finding forms. There is a library connected to the app but I often find the forms there confusing. So I google them and import.

I'm not sure how I stumbled upon your program, but I'm glad that I did! It is fairly intuitive, and I've been able to get started, getting documents done, without studying the help guide. So far it exceeds my expectations,
Mr C
Very easy to use Very easy to use. Loved it. Struggled with editing sideways orientated text. Type replaced went a little wonky, it was for a quick edit to a a basic document, not an official presentation, in which case I might have required a more powerful editor.
