Fax without the machine, the line, or the paper
Fax hasn't gone away in healthcare, legal and finance — but the machine can. intSignal online fax sends and receives over a secure cloud connection: inbound faxes arrive as searchable PDFs in your email and the app, and you send from the app, email, or an API. It's encrypted, HIPAA-ready, and every transmission is logged — so you get the compliance of fax without the hardware.

Receive
Faxes arrive as PDFs — in email and the app
Incoming faxes are converted to clean, searchable PDFs and delivered to email inboxes, the intSignal app, or routed to the right team — no busy signals, no paper, no walking to a machine. Multiple people can share a fax number and everyone gets the document instantly.
Send
Send from the app, your email, or your software
Attach a PDF and send from the app or straight from email — or trigger faxes programmatically with the API for document workflows. Broadcast to many recipients at once, with automatic retries and delivery receipts so you know it arrived.
Compliance
Built for regulated document exchange
Transmission is encrypted in transit and at rest, a HIPAA Business Associate Agreement is available, and every send and receipt is written to an audit trail with policy-based retention. That's what makes cloud fax viable for PHI, signed agreements and financial records — not just convenient.
Retire the fax machine
We'll port your fax number, set up secure fax-to-email and API sending, and map retention to your compliance needs.
