What is Online Faxing?
Online fax services allow you to send and receive faxes over the internet without a fax machine. To send a fax, you typically need to combine the pages you want to send into a single digital document. Then, you upload the file (usually a DOC, JPG, PDF, or PNG) to the fax service. You can fill in additional information, such as the recipient's name and fax number, and add an optional cover page. The online fax service takes care of the rest. The recipient receives the documents just as if you had sent them via a fax machine.
To receive faxes through an online fax service, you need to have a paid account with an associated fax number. In most cases, you either log into a web portal to retrieve digital copies of the faxes you receive or access them via email.
If you plan to use an online fax service regularly, for example, more than once or twice a month, you will likely need to pay for a subscription. Otherwise, you can use a free service like FaxZero, or you can pay per fax with other services like Dropbox Fax (formerly HelloFax).
How Much Does Online Faxing Cost?
Most online fax services require you to sign up for a subscription and pay a monthly fee. Each subscription typically includes a set number of pages you can send each month. Some companies differentiate between the number of pages you can send and receive, while others offer a bundle of pages, which is a more flexible approach.
