Are faxes instant? No. A fax is a phone call in which pages are sent as audio at a negotiated speed, and the pace is set by the slower of the two devices, so a page takes on the order of a minute and a short document a few minutes. That makes fax far faster than mail and far slower than email, which is the answer to is faxing faster than mailing. This page gives the timings the way an online service's sent log records them, and says what makes a fax fast or slow.
How fast does a fax go through
The handshake at the start of the call, defined by the ITU's T.30 recommendation, takes seconds and sets the speed. At the speeds most receiving machines still negotiate a standard text page takes roughly a minute; a modern service to a modern receiver can be quicker, and a page dense with images or a noisy line can be slower because errors force retransmission. Then each page is confirmed. So how long for a fax to go through is the page count in minutes, plus one, in the ordinary case. Is fax instant in the sense that email is? No, and it never was; what a fax gives instead is a confirmation from the receiving device that email cannot.
How long does fax take to send from an app or a browser
Upload or photograph the pages, type the number, press send: the service converts the document in seconds, dials, transmits at the page rate, and returns a report. How long does it take a fax to send end to end is therefore a few minutes for a few pages, and the report arrives when the last page is confirmed. Where people experience a slow fax it is the retry loop: the receiving number was busy and the service tried again later, so how long do faxes take to send reads as an hour in the log while the transmission itself was three minutes. Watching the sent log tells the two apart.
Is faxing faster than mailing
Yes, by days. A mailed page is delivered in days; a faxed page is delivered in minutes with a confirmation. That is why courts, agencies and clinics that will not accept email attachments still accept fax: it is the fastest method that produces a delivery record without an account at both ends. Against email, fax loses on speed and wins on the confirmation and the point-to-point call. A business that needs both the speed of email and the confirmation of fax uses an online service, which sends from a browser in the time an email takes to write and returns the fax report afterwards; plans with a number included start at Fax.Plus's printed $6.99 a month.
Questions people ask about are faxes instant
Can a fax take hours?
The transmission cannot; the retries can. A busy or unanswered number makes the sender retry at intervals, and the elapsed time in the log reflects that.
Is a fax faster than a scan and email?
No. Email is faster. Fax is chosen where the recipient only accepts fax or where the delivery confirmation matters.
What makes a fax slow?
An old receiving machine that negotiates a low speed, a noisy line that forces retransmission, or image-heavy pages. The sender cannot change the first two.
