Come inviare un documento via fax?

Prepare your document, send it to a fax number, and check the result.

To fax a document online, sign in to Fax.Plus, enter the recipient’s fax number, attach your file, and send. Check that every page is complete and readable before uploading, then save the transmission confirmation. You can use an existing digital file or a clear scan of paper.

Before you fax your documents

Check the document you intend to send. A successful fax transmission cannot fix an unreadable page, missing entry, or incorrect destination.

Passo 1

Check every page

Make sure text and signatures are readable. Rotate pages upright, include all required pages, and put them in the intended order before uploading.

Domande frequenti

Do I need to print my document before faxing it?

No. Attach a supported digital file directly in the Fax.Plus web or mobile app. If you only have paper, make a clear scan first. You do not need to print a digital document just to send it to a fax number.

Can I send a document without a subscription?

Yes. A new Free account includes up to 10 one-time sending pages after signup and mobile-number verification. Extra sending credit is available without a recurring subscription, with a $10 minimum top-up and no expiry. Destination and transmission duration affect usage, and connected failed attempts can use credit. Receiving faxes, Email-to-Fax and sending to certain high-rate destinations require a paid plan.

How should I handle sensitive documents?

Check the destination number and use your organization’s approved sharing process for work documents. Fax.Plus encrypts stored files at rest using 256-bit AES, with unique encryption keys for each user. A transmission confirmation does not replace the recipient’s own acceptance requirements.

How long will my document take to transmit?

Transmission time depends on the number of pages, document complexity, connection quality and the receiving fax machine. Scans and detailed images can take longer than simple text. Wait for the final status before treating the fax as successfully transmitted.

How do I know my documents were sent?

Check the final status in your Sent folder and save the confirmation report. Success means the receiving fax machine acknowledged the transmission. It does not confirm that a person read or accepted your documents. Contact the recipient if you need that additional confirmation.
