Think faxing requires a bulky machine, a dedicated phone line, and a roll of thermal paper? Not anymore. With FaxDoc, you can send a professional fax directly from your iPhone — in under a minute, from anywhere in the world.
Whether you need to send a signed contract to your lawyer, submit medical records to a clinic, or forward a government form, this guide walks you through the entire process step by step.
What You'll Need
- An iPhone running iOS 15 or later
- The FaxDoc app installed from the App Store
- A document ready to send — PDF or photo (JPEG/PNG)
- The recipient's fax number (including country code)
- A subscription or credits in FaxDoc
Step 1: Open FaxDoc and Tap "New Fax"
Launch FaxDoc on your iPhone. On the main screen, tap the "+" button or "New Fax" to start a new transmission. You'll be taken to the compose screen where you'll build your fax from scratch.
Step 2: Import Your Document
Tap "Add Document" and choose your source:
- Files — browse any PDF stored locally or in iCloud Drive, Dropbox, Google Drive, etc.
- Photos — select one or more images from your Photo Library.
- Camera — snap a photo of a physical document on the spot.
FaxDoc supports multi-page documents. You can add multiple files and reorder the pages by dragging them before sending.
Step 3: Add Your Signature (Optional but Common)
One of FaxDoc's most used features — sign the document right inside the app before sending.
Tap "Sign", draw your signature with your finger (or Apple Pencil on iPad), and place it on the correct page. Resize and reposition it until it looks right. No printing, no scanning — your signed document is ready in seconds.
Step 4: Enter the Recipient's Fax Number
In the "To" field, enter the recipient's fax number. Make sure to include:
- The country code (e.g., +1 for USA/Canada, +44 for UK)
- The area code
- The local number
Example: +1 212 555 0100
You can also fill in optional fields like your sender name and add a cover sheet with a short message to the recipient.
Step 5: Preview Every Page
Before sending, always preview your fax. Tap "Preview" to scroll through every page as the recipient will see it. Check that:
- All pages are included and in the right order
- Your signature is correctly placed
- The document is legible and not cut off
- The cover sheet (if added) looks correct
Step 6: Send and Track Delivery
When everything looks good, tap "Send Fax". FaxDoc will begin transmitting your document. You'll see a real-time status update:
- Sending — transmission in progress
- Delivered — the recipient's fax machine confirmed receipt ✅
- Failed — the line was busy or unavailable (you can retry)
All sent faxes appear in your History tab so you can track them and resend if needed.
Tips for a Successful Fax
- Use high-contrast documents — fax is black and white, so colorful documents may lose detail. PDFs with clear black text work best.
- Double-check the number — a wrong digit means your document goes nowhere (or to the wrong recipient).
- Send during business hours — some older fax machines are only on during work hours.
- Retry on failure — if the line is busy, wait a few minutes and try again. FaxDoc makes it easy to resend from your history.
