What do you like best?
Easy to use, anyone who I've sent a file has had no issues receiving and downloading. Some of them have told me they've gone on to use the product regularly themselves.
What do you dislike?
Nothing to do with pdffiller, but I sometimes forget to set up the files I'm uploading in the right folders. That's on me.
What problems are you solving with the product? What benefits have you realized?
Under the 'documents' tab, the 2 columns on the right could be made more distinctly different from each other to denote they are in fact different. They are just two shades of gray and not that different in tone.

Easy, and very convenient. Saves me lots of time. It's fast and easy, navigation of the site is easy, uploading and editing a document is easy, the SendToSign option is phenomenal! As of right now I have not really come across any thing that I dislike. The site is pretty self explanatory.

Verry helpful! Things I would change would be to add a paint can where you can color in an entire section. The only other problem i have encountered which may be my own doing is when i edit something and save it and then attach it in an email it looks blurry no matter what i try. Overall the website is great!

The PDF filler is amazing. It has solved me in so many situations since being in isolation due to the fact that I do not have a printer. So easy to use. The only feedback is the date component is fiddly and doesn't always work but other than that - perfect.

Occasionally, you or the signer may choose to lock the document after signing. In this case, the document becomes read-only and no further changes are allowed; even a signature can't be added in the document. The Lock document after signing option is useful if you're the last signer or the only one signer.
1. With the form fields added to the PDF, right-click on the Signature field you are wanting to edit and choose Properties. Then from the Signed tab, choose to Mark as read-only and select the fields you want to lock after signing. Finally, Close.
