​If you are always on the go, you can fax a PDF directly from your phone by downloading a mobile fax app for iPhone or Android. Simply open the app, attach the PDF, and fill out the number before clicking on Send.

Types of Fax Apps

There are two types of apps out there: those that come as part of an online fax service, and those where you need to pay for each fax you send.

​The first option gives you more flexibility because if you are not on your phone, you can simply fax the PDF document from your desktop computer or with your email.  But you need a monthly plan.

The second option is better suited for those of you who only want to send an occassional fax.  Why? Because although paying per fax can end up being more expensive than paying for a monthly plan, it really doesn't matter when you are just faxing a couple of pages.

In any case, make sure the service and app you are using is compatible with PDF.  Some apps only let you fax documents "scanned" with your phone's camera.

​Option 3 - Fax Websites

​​If you want to fax files from your computer without spending any money, you can use a website that lets you send fax free. These websites let you send up to two pages per day,​ and most of them support PDF ​to fax.  The two best free fax services we recommend are MyFax Free and FaxZero.

Do We Recommend Them?

But… well we wouldn’t recommend sending fax online with these services if faxing is a serious part of your office. This is because with these services you are not only limited in terms of quantity, but each of your faxes may or may not arrive with a cover page with ads.

If, on the other hand, you never send a fax and need to send one right now, they are a pretty good alternative. And saves you from having to find the nearest office store.

If you are planning to fax regularly, you will be better off with an online fax service, since these “free” websites then charge you a certain amount per page, which can quickly become more costly than a service that lets you send 300 pages per month.

If you are looking to start without spending money, a better alternative is to sign up for a free trial, this way you will be able not only to send but also to receive faxes during a full month.
