Does everything a PDF editor should, except when a signature placement is required. The signature is squeezed into a field that miniaturizes the graphic.

I have used PDF filler a couple of times and so far I love it! Just a little suggestion, maybe you can add/give the option to be able to change the size of the fonts without having to add a text box where there is already one to fill (does it make sense?). Thank you!

I super recommend it! Editing PDFs when you don't have the source document's has never been easier. You can erase what's written and replace it. What I like the least is that this software is a little bit slow sometimes. But overall, I recommend it.

What do you like best? PDF filler has allowed me to not only make forms being filled out easier but also allows me to keep them archived on their server so I had don't have to look for them. What do you dislike? I think the only downside I would say is the send to sign can be a little confusing. Some of my clients have had issues trying to sign things when I've used this feature. What problems is the product solving and how is that benefiting you? The only time I've had issues is when a form wouldn't load to the system. Customer service has always been great helping me out. They usually have the problem resolved quickly
