How to fax a PDF

PDF is the best format for faxing: the pages are already laid out, and they arrive exactly as they look on your screen.

FastFax lets you send a fax online from your phone or computer for as little as 2¢ a page, with no subscription. US fax numbers only, up to 100 pages per fax.

Fax a PDF in 4 steps

1. Open fastfax.app and tap Upload documents.
2. Pick your PDF. You can add more PDFs or photos; they're sent in order.
3. Type the fax number and, if you want, add a cover page.
4. Check the preview of every page and tap Send.

Size limits

• Up to 100 pages per fax (plus an optional cover page)
• Up to about 24 MB for the whole fax

Every page is resized to US Letter for the fax. Color pages are sent in black and white, as all faxes are, so check that light-colored text is still readable in the preview.

Password-protected PDFs

If the PDF needs a password to open, remove the protection first (open it, then print or save it as a new PDF), otherwise it can't be read for faxing.

Fill and sign before you fax

On iPhone, open the PDF in Files and tap the markup pen to fill in text and sign. On a Mac, use Preview. On Windows or Android, Adobe Acrobat Reader (free) can fill and sign. Save the filled copy and upload that one.

Price

One page credit per page: from $2.97 for 3 pages to $19.99 for 1,000 pages (about 2¢ a page).
