The service is great and the price for fax service is much less expensive than other companies. I love the fact I can fill out documents then email, fax, or file them away.

So far I absolutely love it. I figured out that I can have my clients sign things electronically through this and I swear that alone makes it worth its weight in gold!

Customer Service Is Great I used this service while at work and as a functional feature it is great, does what one needs it to do. However, as sometimes happens, I needed to charge this to my personal banking account at the time. When I left the company, I contacted their customer services team via their web based chat service and a kind lady named Monica answered my query. She was very helpful, diligent in helping me locate my details, and took her time to reassure me that the service subscription had ended and evening was a-ok. I know if I ever need to use this service I will come back, and part of the reason is because the customer care was absolutely spot on. Would recommend.

Convenient, Affordable, Online PDF Editing & Mgmt Tool I use PDFfiller on a regular basis. The enhanced security options, including the ability to email a PDF to someone and that automatically includes a 'security code' for retrieval of the document gives me a sense of security since the actual document is not attached to the email, which could be intercepted if someone hacked into your mail server. I also use the merging tools, allowing me to combine multiple PDF's into one file, move pages, etc. It helps me to better organize my PDF libraries. Considering the other options of using a very high-priced service/product (Acrobat), PDFfiller is, in my opinion, a much better tool. I've been using 'PDFfiller', for the last 2 years. The editing tools available are great, including filling out forms, editing text, adding comments and signatures, makes it a very convenient to import and work with documents on-the-go. The ability to import/export to/from cloud-based sources as well as drag & drop. Import options makes things much easier in-terns of document management Honestly, there haven't been any tasks that I typically need to with PDF editing, etc. that PDFfiller already provide.

Perfect for College I've been using this for my online math course worksheets and this has been so helpful. It's easy to type and draw, editing isn't annoying, and the color palate is easy on the eyes.

I cancelled the subscription 11/11/2021… I cancelled the subscription 11/11/2021 and pdffiller took my money via PayPal at 11/12/2021. I don't understand why. It's no honest. I don't even have an account on your site Edit: I'm very satisfying with customer service of pdffiller. They returned my money. Thank you
