Frequently Asked Questions

Can I receive a fax online for free?

Yes. Send Fax Pro offers free credits to test online fax receiving and confirm the workflow before committing. According to the ITU-T T.30 fax protocol standard, modern internet fax services transmit documents as encrypted digital files rather than analog signals, enabling reliable online delivery without a physical fax machine.

Can I receive fax documents by email or on my phone?

Yes. Send Fax Pro delivers incoming faxes directly to your iPhone as viewable documents. The app supports mobile inbox access and email-friendly document handling. Over 17 million fax pages are still sent daily in the United States alone, according to industry estimates — online fax services handle a growing share of this volume.

Is online fax receiving secure?

Yes. Send Fax Pro uses TLS encryption for all transmissions and does not store documents on servers after delivery. This meets the security requirements outlined in HIPAA (Health Insurance Portability and Accountability Act) for protected health information and is suitable for legal, financial, and healthcare fax workflows.

When should I use the live fax test page?

Use the test page before sending important submissions so you can verify the fax route, document formatting, and delivery confirmation without risking a business-critical fax. Testing takes under 60 seconds and uses one free credit.
