Fax anything, anywhere. No machine.
Halfax.ink sends and receives real faxes over IP phone lines to any fax number on Earth, from your browser, your email or your phone, with proof on every page.
Proof, every time
No more “did it go through?”
Every fax you send comes back with a transmission report: the number it reached, how many pages landed, how long it took, and the far machine's own ID. If a page fails, Halfax resends just that page.

How it works
A file goes in. Paper comes out on the other side.
Halfax carries your fax as data the whole way to the phone network, using the fax-over-IP standard built for it, so jitter and lost packets don't wreck the call.
- Your documentA PDF, a photo of a page, a Word file, or an email.
- HalfaxTurns it into fax pages and adds the sender header to every page.
- SIP + T.38The fax travels as packets with built-in redundancy.
- CarrierHands it to the phone network in the right country.
- Fax machineIt prints at the other end, and the report comes back to you.
If a line refuses T.38, Halfax retries on a second carrier at a slower, safer speed. Receiving runs the same path in reverse and lands in your inbox as a PDF.
