Frequently Asked Questions
Can you really send a fax online for free?
Yes. FaxZero and GotFreeFax let you send faxes daily with no account and no credit card. Limitations apply: US and Canada only, 3 pages per fax maximum, and FaxZero places an ad on the cover page of every free fax.
Which free fax service requires no credit card?
FaxZero, GotFreeFax, Fax.Plus (10 lifetime pages), and FaxBurner all work without a credit card. FaxZero and GotFreeFax don't even require an account — enter the fax number, upload your document, and send.
Can I send a fax from Gmail for free?
Yes, using the Fax.Plus Gmail add-on from the Google Workspace Marketplace. Address your email to [faxnumber]@fax.plus, attach a PDF, and send. This draws from Fax.Plus's 10 free lifetime pages. See our full walkthrough in the [guide to sending a fax from Gmail](/blog/send-fax-from-gmail/).
Are free fax services HIPAA compliant?
No. FaxZero, GotFreeFax, FaxBurner, and the free tiers of Fax.Plus and Dropbox Fax are not HIPAA compliant. Do not use them for medical records or any Protected Health Information. The only free HIPAA-compliant option is Doximity DocFax, available exclusively to verified US healthcare clinicians.
Can I receive faxes online for free?
FaxBurner lets you receive up to 25 pages per month free, but the inbound number resets every 24 hours. Doximity gives licensed clinicians a permanent free fax number. Most other free services are send-only — a dedicated inbound number requires a paid plan.
