How do I send a fax with FaxTerra?
A fax is a document sent to another fax machine over the phone network. FaxTerra does the calling for you — you pick a document and a number, and we deliver it. Here is exactly what to expect.

What you can send
You send a document from your computer or phone — no fax machine, no printer, no phone line of your own. FaxTerra accepts:
- PDF files
- Photos and images (including the HEIC photos an iPhone takes — no need to convert them first)
You can attach more than one file to a single fax; they are combined and sent together as one transmission. Word documents and other file types are not sent directly — save or export them as a PDF first, then attach the PDF.
Choosing where it goes
Every fax goes to exactly one recipient fax number. As you type the number, FaxTerra helps you enter it correctly and, for common destinations like government offices, can recognize the number and confirm what it is. Sending the same document to two different places is two separate faxes. See which countries you can fax.
The optional cover page
You can add a cover page with a short note to the recipient — a subject line and message. It is optional. If you add one, it counts as one page of the fax, the same as any other page.
How pages are counted
A "page" is a page of the fax that actually goes out. If you attach a three-page PDF and a one-page photo, that is four pages; adding a cover page makes it five. This matters because your allowance is measured in pages — see what you can fax for free and what the plans include. A single fax can be up to 350 pages, and the files you upload can total up to 200 MB.
What happens after you press send
Pressing send is all it takes — there is no separate confirmation step to hunt for. FaxTerra prepares your document, places the fax call, and shows you a live status while it works. You do not have to stay on the page: we email you the moment it is delivered, or if it could not get through. See how delivery and confirmations work.
Frequently Asked Questions
Do I need a fax machine or a phone line?
No. FaxTerra sends the fax for you over the internet. You only need a document and the recipient's fax number.
Can I send a fax from my phone?
Yes. You can send from any web browser, or from the FaxTerra mobile app. You can attach a photo taken on your phone directly — including the HEIC format iPhones use.
Can I send one fax to several numbers at once?
Each fax goes to one recipient number. To reach several recipients, send the document to each number separately.
Can I send a Word document?
Not directly. Save or export it as a PDF first — most word processors can do this from their Save As or Export menu — then attach the PDF.
How big a document can I send?
A single fax can be up to 350 pages, and your uploaded files can total up to 200 MB. For anything larger, split it into more than one fax.
