I had issues at first as connections failed and I lost my documents that I had updated which took me a long time to do. I have had another go and it has worked a lot better.

Works as you would expect. No flaws, other than I would like to see a way to make the 'circle' option larger for when initials are needed. Great options here.

What do you like best?
The best feature of PDFFiller is its ease of use, whether it's editing documents, signing documents, and then being able to access your documents anywhere by logging onto the site, as opposed to being constrained if you don't have your computer files with you.
What do you dislike?
Some of the option menus should be improved upon, especially as far as layout and ease of finding what you need, it's a bit counterintuitive though with experience that becomes less of an issue.
What problems are you solving with the product? What benefits have you realized?
Signing PDFs with ease. Being able to access and edit a pdf no matter where I am as long as I have internet access, even if I don't have my computer with me and/or don't have access to my cloud storage.

I have tried a few other cloud based… I have tried a few other cloud based PDF Editors and PDFFiller is the most powerful and easiest to use. Their support has also been great when I had a billing question/issue.

Cancelling a subscription can be an intimidating and anxiety creating experience. NOT WITH THESE PEOPLE!!! Today I logged in to my account. ***** linked in as my Chat contact and in less then 1 minute the subscription was taken care of for me!!!! I have had to fight too many providers about cancelling subscriptions so THIS WAS REFRESHING!!! Such a contrast and it makes me want to stay connected with them if I ever need their services again.Don't hesitate to access their services and products.
