It took me a bit to figure it out. Your guide was confusing and l tried to read it but l didn't find it helpful but l did figure it out on my own. I was fine after that.

I was in a jam! Law School needed me to fill out three documents and sign them and return. The only problem was that I did't have a fax, or scanner. With PDF filler I accomplished my mission at a fraction of the time and cost.

I'm in my second year of subscribing to PDF Filler. I use it for filling all my online forms, related to legal documents and other forms related to my business. I like it, because I can use it anywhere, and I am not tied to one computer, in order to access it.

What do you like best?
How simple it is to use. I can sign on anywhere and make edits to pdf's. I can also convert documents. I've been using pdf filler for almost 3 years now and absolutely love it! Just renewed my subscription for year 4!
What do you dislike?
No complaints. Even on the rare occasion where the system crashes, the pdf filler team sends you an email to let you know they're working on correcting the problem. It's usually fixed within minutes.
Recommendations to others considering the product:
Don't think about it twice, use it!
What problems are you solving with the product? What benefits have you realized?
Last minute edits. Also love the signature feature that includes the dates. That comes in very handy in my field, which is real estate.

Though it appears to require a very fast internet provider in order to use it properly, I am satisfied and would highly recommend it.

What do you like best?
I love that I can fax items as well as the W-2/1099 features that are integrated into the IRS system! It makes my roles as a small business owner much easier with these tools.
What do you dislike?
I wish more features, such as sending documents for signatures, were added. Even just 1-2 documents a month would be helpful for my small business. A fax number included would also be helpful. I have been able to get a fax number for virtual faxing for much cheaper elsewhere. It would be nice to have an all in one for less than $25 a month or so.
Recommendations to others considering the product:
Great way to keep costs low while still running with the bigger companies and their larger budgets. From creating my own documents to faxing things for clients- great investment for virtual tools in your business!
What problems are you solving with the product? What benefits have you realized?
The IRS integration have helped me navigate some of the tax paperwork I need to do for my employees. The fax feature is super helpful for getting paperwork out for our clients.

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!

REAL EASY TO USE
REAL EASY TO USE, INTUITIVE, EASY TO FIND THE NEEDED OPTIONS.
ONE THING IT LACKS IS THE FEATURE TO COLUMISE THE TEXT. LIKE ALIGNING TO CENTER, LEFT, RIGHT. IT WOULD BE GOOD TO HAVE THE OPTION TO DO THAT. LIKE THE ONE MICROSOFT WORD HAS.

Perfect for merging multiple JPG images into a compact PDF
This app / web page allowed me to easily merge six JPG image files (each 2550x3300 pixels, some included photos) into a single compressed PDF document that was small enough (7MB) to be easily shared as an email attachment. Did exactly the job I wanted it to!
