What do you like best?
I like that the website is very easy to use and allows many different functions, including digital signatures and saving directly into your computer. I also like the options to save a template to use, which saves me a lot of time as I am always using the same forms.
What do you dislike?
I dislike that I always have to log in again every time I use the website.
What problems are you solving with the product? What benefits have you realized?
Digital signatures. Being able to edit PDF with a Mac since most PDF programs are only compatible with windows.

All i needed was the Rewrite PDF mode, All i needed was the Rewrite PDF mode,but you hide it took me almost 30 minutes to find this.And almost get out from this site..if you see i'm uploading a PDF file, suggest me the rewrite mode from within the Preview mode, (or on right click on the document - with the remove to trash and all the other options)

Perfect for on the go! Time saver and so convenient to have this! You can access from everywhere It's very easy to log on away from your desk to edit and send a document for a signature. I'm a logistics manager and I'm always on the go and most of the time I get phone calls away from my desk so its handy to be able to pull this software up on my phone to send important documents - especially customs paperwork when zip need to Nothing! You can pretty much find any document form needed in their library to assist you with your needs. You can even edit the document if need be.

Great after-sales support! I recently signed pdfiler demo version to convert a PDF to a word document but for for some reason it didn't work, not the point. Point it, I forgot to cancel my subscription and was billed for the year. I immediately cancelled my subscription and contacted pdfiler via the online chat. That answered within 20 seconds and immediately refunded my payment. Really great service - thanks!

Helpful for Digital Signature Overall the PDF filler is amazing and free! These days, a lot of people don't have printers and scanners. Also, a lot of us are working from home. This software makes it possible to sign documents without printing and scanning. My least favorite thing is that you have to create an account to save your document. It would be nice to not have to provide my email to save the document.

EXCELLENT CUSTOMER SERVICE Very quick, efficient and courteous customer service. My elderly mother subscribed to this service and couldn't remember why. I explained the situation via emails with Customer Support and they refunded the annual subscription fee after I verified a few details. I really appreciated their understanding and quick response. Now...I have to go unplug my mom's computer. :-)

Well it worked. But, I was tricked into the 30day trial by populating a document you do not own. I could have done this without needing an account albeit "free trial." I don't think I need this service full time. It's way too expensive for an infrequent user.
