Frequently Asked Questions
Can I receive faxes online without a fax machine?
Yes. Sign up for an online fax service like mFax.to, get a virtual fax number, and incoming faxes are delivered as PDFs to your email — no machine, no phone line, no paper required.
What is the best way to receive faxes online for free?
Most services that offer a permanent dedicated fax number for receiving require a paid plan (starting ~$7–12/month). FaxBurner offers a limited free tier with a temporary number. For ongoing business use, a paid plan is the only reliable option.
What format are received faxes delivered in?
PDF is the standard across all major online fax services. Some also support TIFF. Premium tiers on services like iFax offer OCR-searchable PDFs.
Will I miss faxes if my device is turned off?
No. The service's cloud servers receive and store faxes 24/7 regardless of whether your device is on. You'll get the PDF in your email as soon as the service processes it.
Can I keep my existing fax number when switching to online receiving?
Yes. Most online fax services support number porting, which typically takes 7–14 business days. With [mFax.to](https://mfax.to), you can port an existing number in so senders never need to update their records.
