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.

I was extremely happy with PDFFiller until I took an entire 2 hours worth of notes on a pdf and the website froze when I tried to save it. And then lost it all with no recovery option.

Amazing Anna! I was fighting with a document for two days! Anna from pdfFiller helped me via chat and she was FABULOUS!! I would have never been able to finish my document without her help! Thank you!

So far, so good So far, so good. Does as it claims to.Some of the functions e.g. merge could have more accessible controls (you have to gone into a few menus), but when found they do their job well.Maximum document size is 25Mb so if you have a bigger document you have to use another online splitter and go from there. Don't really see why that functionality could be integrated though.

The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
