I love that you can turn any document or picture into pdf. As a loan officer, I need copies of driver's license and social security. Everyone has a nice phone but the format is not PDF. This PDFfiller is the best. It only has a few fonts. That is the reason for the 4 out of 5.

What do you like best?
I like the ability to send to sign documents the most. I use it in my business daily. I like the features to organize my documents and to make templates. The templates are a life saver. Also, PDF filler has a large library of documents, anyone can easily personalize templates, can prepare add signatures, dates and finalize documents all in one step, saves time, LOTS of time!
What do you dislike?
I like it all. I don't have any complaints.I have used other document signing programs and they are way more difficult to use. No so with PDFfiller. The mobile app is not that easy to use as the (desktop) version. If I had to say Sometimes there is a delay from screen to screen. But that could be connection.
Recommendations to others considering the product:
If you need a document editing tool that does everything you can think of USE PDFFILLER it ROCKS! If you need to use this product to mark up documents and sign, try this product! I like to keep everything that I do 100% electronic, so with products like this, I am able to do so.
What problems are you solving with the product? What benefits have you realized?
I can get leases and contracts signed very easily. I like the ability to get clients to sign contracts and leases on their mobile phones. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.

How often does one get 5 star support? How often does one get 5 star support? Unfortunately the answer is not often at all. But today was different. I got 5 Star Customer Support from Kara on Team PDFFiller. More importantly Kara was patient and guided me to work through the problem with my login issue. Success all the way around. Happy customer is a loyal customer. Thank you Kara.

Reasonable but not fantastic Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it. The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use. Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.

Good Quality My experience with PDFfiller is old, when I still needed to install the software. Nowadays I don't use it anymore, but in my college days it was very useful. The conversion of documents on the PDFfiller website is quite simple and does not change the structure of the actual document, which can be up to 150 pages. For most files, this is a good size. I find PDFfiller useful only for those who work with many documents to pay a monthly fee that is not high, but it is still something to consider.
