Part 1. Can You Send a Fax Directly from Gmail?
Gmail doesn't support faxing directly. You won't find any built-in option to fax documents through Gmail. However, that's not the end.
You can still fax documents through Gmail using an online fax service provider. Fax.Plus and HelloFax are two popular online fax providers that integrate with your email account.
These platforms allow you to send faxes by simply emailing your document to a special fax address. Think of them as a bridge between your Gmail and the recipient's fax machine.
Simply put, Gmail itself cannot send faxes, but its integration with online fax services makes it possible. Head to the next part to learn how to send a PDF fax from Gmail.
