I needed some legal forms quickly in a divorce case. The forms were exactly what I wanted and needed. PDFiller allowed me to do it quickly and easily. The option to color filled in text would be great.

Easy to use
Easy to use. Only one downside - can't bring in any other types of fonts. That would be helpful. Other than that it's good for my needs.

Great product and customer service
I have been using PDF filler for two years and I am very satisfied with the product. For the first time today, I could not figure something out and sent a question to customer service. Within a very short time I got a response that solved my question. Great customer service.

Overall it's a great website but some improvements needed such as insert a table for data option, and wish it was actually free forever!

I would love to attend a webinar eventually, but time right now does not allow it. I have been extremely pleased with pdfFiller and recommend it to everyone I know who has to fill out a lot of forms.
Maybe slower than hand writing , but legible which is extremely important. My biggest issue is somehow I have two accounts with other documents saved and do not know how to merge them. That was my problem not realizing i had an account already. Thank yall so much!!!

Good PDF Form Filler software
Was able to manipulate the text size to make sure everything fit into the text boxes I had to fill out. By approaching each set of box as one text, it cut down the time needed to fill out the form.
