HelloFax makes it easy to sign documents and send faxes online. You'll never need to print, sign and fax documents again! 1) Send faxes Put in a fax number and we'll send your document to a fax machine. It’s as easy as sending an email attachment. You can also send any file in your Google Drive. 2) Receive faxes If someone sends you a fax, we'll forward it to your email and Google Drive as a PDF. You never have to touch a fax machine. 3) Sign documents & fill out forms As soon as you upload the document, you can add your signature and fill out forms. We take over 30 different file types. Once you have signed or edited the document, you can send it via fax.
