pdfFiller scores top ratings on review platforms
Performance is slow and choppy at times. There is no OBVIOUS way to turn off the popups every single time I go to fill out a form. Transitioning from one form to another is extremely disjointed. There is no clear way to fill out one form and simply move on to the next in a series. If there is a clean workflow in there somewhere, it's not obvious, at least, not for my use case, which is to fill out a form for each of my employees from a remote location, download all and print all for distribution. Seems like every time I finish something, it takes a while to save, and a while to get to the page letting me choose what to do next, which is always to display the file list again, and a while to load the file list. . .rather than simply keeping the filelist persistent and hidden, as would seem same here. Also, this form, won't let me enter more than a character or 2 before kicking me out. I am writing this feedback in a notepad and then copying it in all at once. Awesome.
The site is very easy to navigate. I'm a novice when it comes to anything to do with forms, etc. Your site is so easy because it's intuitive. It just makes sense about what to do next, no hunting around trying to figure what the site builders were thinking. Easy peasy.

Excellent, easy to use and saves a lot of time
It has saved me time mainly and a lot of hassles in getting physical signatures.
I have signed and shared documents within minutes rather than signing/scanning or mailing.
If you want to save time and get your documents signed ASAP, PDFfiller is a must have software. You can use it anywhere as long as you're online and you can edit it too without any hassles. It's very affordable.
The one time I used helped they…
The one time I used helped they actually helped. The other service I tried to use before this one, I couldn't get any help.
It is not very difficult to navigate, but I do have issues with finding some of the documents I need. Plus, I feel that the pricing of basic level is too much. I am a person with a limited income and can not afford much. I need this program to help with my taxes and a few other documents, but I can not afford to pay an entire years worth!
********** was the easiest & fastest customer service to resolve a billing issue. If I need to use a document signing company in the future it will most definitely be **********! Thank you ********** Team you truly are amazing! This world needs more kindness in it, thank you for everything!
I had to type information into a PDF…
I had to type information into a PDF document and I couldn't do it in Windows 10; I found pdf.filler.com and was able to type in my information easily!
