What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
For several years I used this service as I ran an on-line business and felt that the ability to create pdf files, for ordering processes would be of a significant help. I am now retired, but like the ability to modify medical health forms rather than filling them out by hand repeatedly.

It was actually nice, easy and convenient to use. It is just that I find it expensive so I revert back to my old ways means manually filing or writing in forms. :)

I liked their services I liked their services, but didn't need them long term. I had thought that I had canceled my account right afterward, but still was charged when the trial period was up. I contacted them on a Sunday, expecting it to take a few days and be a nightmare. Even though it was the weekend they had it taken care of and refunded to me within a few hours! I would definitely use them again because of how trustworthy and understanding the staff was. Good job PDF Filler Team!

What do you like best? Basically, it just works. There is no learning curve, no difficulties, no glitches. It is simple, does what it is supposed to do and more. I can merge sheets, sign docs, fill out forms ... everything that could otherwise be a hassle while working remotely. What do you dislike? It may just be my set up, but when I have completed the document on pdf Filler and click "save as," it downloads to my desktop as opposed to allowing me to set the folder of my choice on my hard drive. Not that big of a deal to open the download and 'save as' from there, but just a small annoyance. What problems are you solving with the product? What benefits have you realized? I often receive documents piecemeal - one page at a time - or I get them back from different signors in different configurations. I love that I can upload them all at once, merge them right off the bat and have the combined document. I can easily rearrange the pages if needed too. Also, during this Pandemic, it has proved invaluable in getting documents easily executed when you cannot meet with signors in person.

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.
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.
A fax machine is designed to both send and receive documents, so it has a sending part and a receiving part. The sending part is a bit like a computer scanner, with a CCD (charged-coupled device) that scans only one line of a document at a time, and only in black and white.
Send or Receive Faxes at The UPS Store If you find yourself asking, “Where can I send a fax near me?” look no further than The UPS Store for all of your faxing needs. Our fax machines are always ready to go. Take advantage of The UPS Store fax services (sending and receiving faxes), and handle your business.
When the receiving fax machine sends a confirmation signal, the sending fax machine prints a confirmation page. As a backup, most fax machines keep logs of the time, date, number of pages, and success status of any fax transmissions.
Yes, you can have a fax number without a landline phone line. To have a fax number and use a fax machine (or computer with fax software) you'll need a landline phone line. VoIP phone lines will not work. A cell phone can fax using an online fax service.
Turn on your machine and let it warm up completely. Plug in the telephone cable to a wall jack and then plug the other end into the Line In port on the back of your fax machine. If it has a handset, pick it up and listen for a dial tone. Your machine needs a working telephone line to send and receive faxes.
To send the wireless fax, make sure your computer and printer are turned on and running on the same network. Your HP printer without a phone line works just fine when it is hooked up to the wireless network. If the printer does not have a fax tray, you must scan each page of the document before sending the fax.
