This application solved my work! I am constantly receiving email with PDF attachments which I must review immediately and in many cases merit that I fill or edit them, for which I had to download the mail file and manipulate it to send it again. Well that I finish since discovering this extension for my mail, through it I open and edit online from my mail the file received. This speeds up the tasks. The only thing I should mention is that being an online job, the Internet connection must be constant and efficient so that the work flows quickly.

Everything is easy to use Everything is easy to use. I was having some issues faxing and got a quick response from support. Other than that great experience so far. It would be cool if I could request documents from clients where they can upload and it would go to my docs in pdf filler.

I went into your chat hoping to get… I went into your chat hoping to get answers to my inquiries regarding my account and why I couldn't locate what it kept telling me that I should be seeing. Kara was the second chat agent I messaged in this desire to find out what I was doing wrong... which is fine. The first agent was like an operator I assume... finding out what I needed exactly and then transferring me to the right team. Which happened really QUICKLY!! I am NOT used to any online chats actually being able to do anything as fast as this happened today! Much less get an agent that could actually help me... TODAY was the first in a very LOOOONG time! Kara was GREAT!!! She needs a raise and maybe a promotion. Thanks again, Kara!!! KUDOS to Kara!!! The one entity that I HAD dedicated my loyalty to (Best Buy) for over a decade... is now in my rearview mirror!!!! They are atrocious at helping anyone with anything online!!! The store employees have to go through the same phone number we do, so they're worthless! And corporate Best Buy... smh... I won't get ugly here, but just state that they were the final straw that broke the camel's back!! I will NEVER give them any more of my time or money!!! PDF Filler though... has been a nice change!!! Thanks again!!!

If you ever happen to chat with Support… If you ever happen to chat with Support for a technical issue --- Hope you get Paul. Paul worked with me for nearly and hour trying to figure out why my form got skewed. I shared out my screen with him -- he diligently and carefully figured out the problem and got it fixed. Saved the day! Kudos to Paul!!
