Very Quick, saves me a lot of time. I regularly get pdf's that need to be completed and sent back. Now I can upload, fill out and return in a fraction of the time. Since the data is typed, I never get a question about what I wrote.

There have been a few times I have been frustrated because I can't access my documents. Get an error message but other than those 2 times I am extremely satisfied with it

Handy service, wish it was a little cheaper and a little more intuitive. It should be easy to fill in a form over and over but there is no save as, so you end up redoing your work a lot as it saves over it.

Something went wrong, when I was filling once it stopped me suddenly. It saved the work, luckily. But I lost two minutes to restart my job, and this wasn't nice.

Excellent website with great features I receive documents from my client's customers that need to be filled out and signed by my client. These are handled by PDFFILLER quickly and efficiently. It's very easy to fill in PDF files and it's just as simple to add and insert signatures. Sometimes movements within the website are a bit lengthy. After downloading a completed document, returning to the exact page would be nice.

Super simple to use. There are only a few things that could use some tweaking like the sizing of the box for the fillable text could be a little simple to make smaller.

What is a Required Field?

The term Required means the fields are obligatory for filling out. If they are not filled out or the user typed in data only partially, the Complete button will not work. The filer will see a notification about the necessity to fill the fixed number of empty fields.

Those fields will usually be highlighted with a dark color. A yellow flag helps you find the required cell. The fields highlighted with a lighter color are optional.
