Can you fax a Word document directly without converting to PDF first?

Yes. Most online fax services — including mFax.to — accept .docx and .doc files directly and convert them on their servers. That said, converting to PDF first is recommended for documents with complex formatting (custom fonts, tables, multi-column layouts) to ensure the recipient sees exactly what you intended.

Does Microsoft Word have a built-in fax feature?

Word has an "Internet Fax" option (File > Share > Email > Send as Internet Fax), but it depends on Windows Fax and Scan being installed and a linked third-party fax provider. This feature is deprecated in Windows 11 version 24H2 and later. For most users, a Word add-in or online fax service is the practical solution.

Can I fax a Word document from a Mac?

Yes — use an online fax service's web dashboard (like mFax.to), a Word add-in (Fax.Plus or WiseFax), or an email-to-fax gateway. The Windows Fax and Scan feature is not available on Mac, but all internet-based methods work on any operating system.

Why is "Send as Internet Fax" missing from my Word?

This option appears only when Windows Fax and Scan is installed and active. On Windows 10, enable it via Control Panel > Programs > Turn Windows features on or off > Windows Fax and Scan. On Windows 11 version 24H2+, this feature has been removed entirely — use an online fax service or Word add-in instead.

What is the best file format for faxing a Word document?

PDF is the gold standard. It preserves fonts, margins, and layout exactly — "a digital snapshot" of your document. Convert with File > Save As > PDF in Word before uploading to any fax service. For simple plain-text documents, sending .docx directly works fine.
