I'm loving everything and I like how I can do so much without printing, then write your info, then scan to your pc, then email to an individual or group. This is way, way faster.

Its good, except that it saves the document automatically without allowing a Save as function when printing, so it overwrites the previous file, which is not so good.

The experience was interesting. I would recommend the company to others but I would make sure that the price is up front before purchase is made. I misunderstood the price of the product. But Again I would recommend the company just for the fact that they are very helpful.

It works for what its for and has some nice features like saved signatures. If you're commonly using this its probably worth getting.

Have not been able to successfully append a document more than 5 pages. That process does not appear to be very user friendly to figure out. Would love some guidance on how to do specific things with this program now that I have purchased it for a year!

Cancelled my subscription within the 30 Trial Period and was charged the following month. Had an online chat and they issued a refund with no questions asked. Good Business!

Ralph - My favorite support friend
I requested a refund for a yearly subscription that I did not remember signing up for. I reached out once before and did not receive a response. I reached out again today (2020-10-24) and Ralph responded right away. He was extremely helpful and nice and solved my problem right away. I am extremely satisfied with my experience and I will definitely keep PDF Filler in mind if I or my friends need a safe place to store or edit documents. Thank you for your great support and for hiring a great employee like Ralph! He is amazing and I truly appreciate him.

How do I edit a DOCX file?
If you need to edit or modify the document, you will need to use OpenOffice. DOCX Word Documents are different from the DOC version in that they use the Microsoft Office Open XML format. The Open XML format makes it easy for other programs, such as Apache OpenOffice, to read DOCX files (and other Open XML file types).
