For usually highly important or legal reasons, FAX transmissions are sometimes required. This PC magazine article shares web based support for these techniques — to emulate a process that is decades old for 2020 needs

Faxes are so 1980s. Who faxes anymore? Well, lots of folks do. Business offices. Small companies. Large companies. And why? Well, let’s say you want your doctor to send you a copy of your latest lab results. Or your financial analyst asks you to send a document authorizing a certain transaction. Snail mail can be too slow. And email isn’t secure. So that leave us with the decades-old but still reliable fax.   But I don’t have a fax machine, you say. How can I send or receive a fax? Lucky for you, an array of web-based services exist that can send or receive faxes without much effort. 

Many web services can send a fax to any number you choose. With certain services, sending a fax is free if you’re transmitting a small number of pages. In this case, the fax service usually places an ad or logo on the cover page promoting itself. If you need to send more pages or don’t want an ad cluttering up your fax, you’ll usually have to cough up some money. Alternatively, many services charge you a monthly fee

Assuming the document you want to fax is in hard copy format, you’ll first need to scan it. You can save the scanned document as a PDF or TIF file, though a PDF is a better choice if you want to keep the electronic version of the file. Typically, you would scan a document using your computer and a scanner or an all-in-one printer. But if you don’t have the necessary equipment, you can scan the document with your mobile phonusing a scanning app.
