MondialFax, how does it work?

Every fax sent from our platform is completely free, whatever the number of faxes or pages. MondialFax will never ask you to pay anything: the entire site is free, with no hidden catch.

No. MondialFax asks for no registration, no password and no payment method. Only your name and an email address are required: the email is used to send you the acknowledgment of your request and the tracking link.

From the MondialFax home page: upload your document as a PDF, choose the country, enter the recipient's fax number, then confirm the send. You need no fax machine, no phone line and no software: a web browser is enough.

Yes. The MondialFax form works in the browser of an iPhone or Android smartphone, with no app to install. All you need is the document as a PDF on your phone.

MondialFax accepts PDF files only, up to 5 pages and 10 MB. A Word document, a photo or a scan must first be saved or exported as a PDF, which every computer and smartphone can do.

To prevent our lines from being tied up for too long, faxes are limited to 5 pages.

If your document is longer than 5 pages, split it and send it in several transmissions.

There is no quota and no subscription: the number of transmissions is unlimited, and each one carries up to 5 pages. You can send the occasional fax just as easily as you can use the service professionally.

One of the strengths of MondialFax is how simply and quickly you can fax several countries. Seven destinations are covered: France, Belgium, Germany, Spain, Italy, Portugal and Canada.

First choose the destination country, then enter the number as it is dialled within that country, without the international code: MondialFax adds it for you. The form shows the expected format for each of the seven destinations and rejects any number that does not match it.

No, and no service can: a fax is a dialogue between two modems, and a smartphone cannot take part in it. MondialFax therefore rejects mobile numbers at input, rather than accepting a send that is bound to fail.

It is not technically required, but many government offices, law firms and hospital departments set aside a fax that arrives without one. MondialFax offers a free PDF cover sheet generator, to place as the first page of your document.

There is no advertising in your faxed documents, and there never will be. Only your document reaches the number you asked for — nothing more, nothing less.

Your document travels encrypted (HTTPS) from your browser to our servers, is used only for the transmission, then is automatically deleted once the send is complete.

The telephone leg to the recipient's fax machine, however, is not encrypted for any fax: the fax protocol does not allow it.

No, and no service can encrypt a fax end to end: the T.30 protocol makes no provision for it, and the last leg to the fax machine travels over the telephone network in the clear. MondialFax encrypts the path between your browser and its servers, then deletes the document once the fax has gone.

The GDPR does not ban fax: it requires you to transmit only what is necessary, to secure the send in proportion to the risk and to react if something goes wrong. Since fax is not encrypted, most precautions concern the right number and where the recipient's fax machine is located.

Under French law, proof is in principle free: a fax can be produced as evidence, whether it was sent from a fax machine or from an online service. But a transmission report proves that a call reached a number at a given time, not the content of the pages or that they were read, and some acts require a form that a fax does not meet.

Email is faster and more convenient, but it can be filtered out without your knowing. Fax produces a confirmation issued by the receiving device itself. The right choice depends on what your recipient accepts and what you will need to prove later.

The most common causes are a wrong number or one that is not a fax, a busy line, a recipient fax machine that is switched off or out of paper, and a line switched to voice over IP that distorts the signal. Your fax status, tracked in real time, shows the failure; check the number and try again.

No. MondialFax sends faxes but does not receive them and does not assign any numbers. To receive a fax, you need a fax number reserved for you, connected to a fax machine or to a fax-to-email service, which is almost always paid for.

Yes. What is disappearing in France, area by area, is the classic analogue line, not fax. A fax machine plugged into a wall socket will eventually lose its dial tone, but an online sending service like MondialFax does not use your line and keeps working.
