pdfFiller scores top ratings on review platforms
So far I have only used it to print the current W2 forms for my employees but it has been really convient. I like the numerous ways you can fill our forms and love the signature features. So far, so good.
great except when i want to email something sometimes the other party can't view it as a pdf. i dont get why. I want an option to save my new document in my own hard drive but can't figure out how to other than emailing it to myself. add that option or help me find it.
I had a problem with a pdf file freezing up on deadline and not being able to copy it when I was on deadline. I have to say, though, your online customer service was extremely helpful in solving my problem.
It is a little hard to learn and it is a little expensive, but it is the best "filler" program I have ever used and I am glad and grateful to have it.
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.

Easy to Use Online Document Filter
Online platform allows for less bulky application. Some users liked that it was online and they didn't have to have an expensive bulky app like Adobe.
There are some features lacking and the website could use a little reboot. For the price, you can't get any better than this but it could still look better. It would be easier to use.
