Everything has worked great and while I honestly don't know what there are companies that still use Fax, they do exist and I need to work with them. Love PDFfiller and everything it provides.

Directions for completing fillable forms were very clear, easy to follow, and concise. This is a great product for someone who is in need of fillable forms on a regular basis. Highly recommended.

The program interface is OK but it could be a little more iterative. A form I was completing for the TSP TP77 and the TP76 did not place the letters and numbers (characters) in the exact center of each box making the document a little harder to read. I know this for sure because I have completed the same document using TSP website filler with the document are available. This would be easy for the company to fix this but they check their forms before making them available.
But the overall online forms filler program works well and saves completed forms easily and has a generous library.

PDFfiller is the best, hands down
I've used just about every PDF filling service I can find and although PDFfiller is on the pricey side, I've found them to be the best because of their drawing features, beautifully organized website on both desktop and mobile, and super fast customer support. If you need to fill out PDF's regularly, I'd say PDFfiller at $6 per month is easily worth the money.

So easy to use and meets all my expectations
Knowing that it's there when I need it. I only use it when I get a new tenant. It also saves my information so I don't have to enter it each time.
I can find any form that I need. I own a small rental business and I am able to fill out my lease and Pd filler saves it and I can fill out the next with just changing the new lease's name and address.

PDF editor that does the job.
It does the job to edit documents to avoid printing and scanning official documents.
I was impressed that I could place the cursor and be able to edit any online document. This enabled me to print or send a document without having to print ad scan the document.
It was difficult lining up the cursor or lining up where I could input information on the document. I would have appreciated a tutorial that was available at the beginning of the trial or purchase.

Sometimes a bit complicated but no other company has my attention yet
This software can edit, find, fax, email, and fix documents. fax is strong, and blacking out and deleting items is nice.
Sometimes you can see where old edits have been made and they print bad.

Pdffiller suits almost all my needs…
Pdffiller suits almost all my needs once I get my files there. If I could have a way of "breaking" my files heavier than 25MB to get there OR if it accepted larger files... it would be perfect!

They were very understanding and willing to assist me with a recent refund I requested. Great customer service! Great company!

How do you use a fax machine step by step?

Do you fax things face up or down?
If the icon has lines of text on the front of it then you should send a fax with the paper face up. If the text lines only appear on the folded corner, send the fax with the paper face down.
How do you send a fax face up or down?
If the icon has lines of text on the front of it then you should send a fax with the paper face up. If the text lines only appear on the folded corner, send the fax with the paper face down.
Which way do you put the paper in a fax machine?
Face Down. When you insert the document you want to fax with the printed side toward the machine, the document's text and graphics are face down against the tray. The fax machine then pulls the document down the tray and scans the document's content.
When scanning a document which side goes down?
There should be a mark showing which side. If scanning from the glass, face down, because the scanner is looking up from under the glass. If using the ADF (most people use ADF for fax for multiple page), face up. (The 8600 is capable of scanning double-sided, but if doing single side, face up).
How does a fax machine work step by step?
In both early and modern faxes, the sending and receiving process revolves around the same basic concept: The machine scans the document. That signal is sent down a telephone line to another fax machine. The other machine decodes the signal and reproduces the document.
Can I fax a document from my phone?
Android apps make it convenient to fax documents directly from your Android smartphone. The Mobile Fax Free app allows you to fax single-page documents for free. Mobile Fax Free will convert a picture taken with your phone's camera into a PDF document.
