Frequently Asked Questions
Is it free to fax online?
Yes — some services let you fax online for free with limits. FaxZero allows 5 faxes per day (up to 3 pages each) at no cost. For occasional faxing with no monthly fee, pay-as-you-go options start around $0.99 per fax. The [mFax app](https://mfax.to) offers a free trial for new users.
Can I fax from Gmail?
Yes. Use an email-to-fax gateway: compose a new email, type the recipient's fax number followed by the service's domain in the To field (e.g., [email protected]), attach your document, and send. Some services also offer Gmail add-ons for a one-click experience.
Is online faxing HIPAA compliant?
Only with the right provider. HIPAA-compliant online fax services must offer 256-bit encryption, a signed Business Associate Agreement (BAA), audit trails, and access controls. See our [guide to HIPAA-compliant fax services](/blog/best-hipaa-compliant-online-fax-service/) for vetted options.
What do I need to send a fax online?
An internet connection, a device (phone, tablet, or computer), your document in digital format (PDF works best), and the recipient's fax number. No fax machine, phone line, or special hardware required.
Is faxing online more secure than email?
Generally yes. Online fax uses point-to-point transmission with end-to-end encryption, whereas standard email travels through multiple servers with no guaranteed encryption. Fax also provides legally valid delivery confirmation, which email read receipts cannot match.
