What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I was shocked to learn AFTER I PAID that the "monthly" payment touted in 3 big choice boxes was ONLY and effective cost IF I paid an annual fee IN FULL. THAT WAS NOT CLEAR and I feel duped. However, I am extremely pleased with what you offer AND the ease of using your site. It is well worth the 29.99/month vs what I thought was 9.99. You really need to make that clear for your customers, though. Don't start a customer relationship with the customer feeling duped or tricked.

Didn't expect a trial... kind of took me by surprise after I used it to file a larger pdf. I like the software but the tactic is a little... predatory?

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.
Do you dial 1 before sending a fax?
Dial a leading '1' when sending a fax only if you would dial a '1' for a regular phone call. As fax works over the phone network, all fax numbers are simply phone numbers and should be dialed the same way as a regular phone call. When calling long distance within the United States and Canada: The leading '1' is added.

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.
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.
Do you scan documents face up or down?
Remember to place the paper that has the information or the picture you want to scan, facing down, i.e., the blank side of the paper should be facing Up. 2. Once you place the document on the paper feeder, you will notice a message on the display screen on the scanner that says Document Loaded.
