By David Thompson · Published March 30, 2026 · Updated April 3, 2026 · 7 min read

You already have everything you need to scan and fax a document from your iPhone. The camera doubles as a scanner, and a fax service like mFax.to handles the transmission. No fax machine, no trip to UPS, no printer required.

This guide covers every method for scanning and faxing from iPhone in 2026 — with step-by-step instructions, scan quality tips, and answers to the most common questions.

In a hurry? The fastest path is the mFax app: scan inside the app, enter a fax number, send. Total time: under 2 minutes.

The Fastest Way: Scan and Fax with the mFax App

The mFax app combines document scanning and fax transmission in one place. You scan, you send — without leaving the app or converting files manually. It's the method most iPhone users should start with.

What you need:

• iPhone with iOS 13 or later
• mFax account (free to create; pay-per-use or monthly subscription)

Method 2: Scan with iPhone's Built-In Tools

If you want to scan the document first and decide where to send it later — or share it via multiple channels — iPhone's built-in scanning in Notes and Files works well without any third-party app.

Scanning with the Notes App (iOS 11+)

The Notes app was Apple's first built-in scanner. It applies automatic perspective correction and saves scans as PDFs.

1. Open Notes and create a new note (or open an existing one).
2. Tap the camera icon at the bottom of the screen, then select Scan Documents.
3. Hold your iPhone directly over the document. In Auto mode it fires automatically; in Manual mode tap the shutter button or press a Volume button.
4. Drag the corner handles to adjust the crop, then tap Keep Scan.
5. Scan additional pages as needed, then tap Save.

To extract the PDF from Notes: tap the scan inside the note, tap the Share button, and choose Save to Files — or share directly to the mFax app.

Scanning with the Files App (iOS 13+)

The Files app saves directly as a standalone PDF, making it slightly more convenient for faxing because you skip the step of extracting the file from a note.

1. Open Files and navigate to the folder where you want to save the scan (iCloud Drive is a good default).
2. Tap the "…" button in the top-right corner and select Scan Documents.
3. Position the camera over the document. Tap Keep Scan after the auto-capture (or tap manually).
4. Scan additional pages, then tap Save.

The PDF lands immediately in the folder you chose — ready to attach to any fax service.

Sending a Scanned PDF as a Fax

Once you have a PDF in Files or Notes, uploading it to mFax takes under a minute.

1. Open the mFax app (or go to mfax.to in Safari).
2. Tap New Fax.
3. Under attachments, choose Import from Files (or iCloud Drive).
4. Navigate to your scanned PDF and select it.
5. Enter the recipient's fax number.
6. Tap Send and wait for the delivery confirmation.

Shortcut: From the Files app, tap the PDF file, tap the Share button, and look for mFax in the share sheet. This drops the document directly into a new fax compose window.

Method 3: Fax from Safari (No App Download)

For occasional faxing without installing an app, you can fax directly through the mFax.to website in Safari.

1. Open Safari and go to mfax.to.
2. Sign in or create a free account.
3. Tap Send Fax.
4. Upload your scanned PDF from Files or Photos.
5. Enter the recipient's fax number and tap Send.

Pro tip: Tap Safari's Share button → Add to Home Screen to pin mFax.to as an icon. It behaves like an app without taking up app storage.

Method 4: Email-to-Fax from iPhone

If you live in email, this method lets you fax without switching to a separate app at all.

How it works:

1. Scan your document (Notes, Files, or mFax app) and save as a PDF.
2. Open Mail, Gmail, or Outlook on iPhone.
3. Attach the PDF to a new email.
4. In the To field, enter the recipient's fax number followed by the email-to-fax gateway (check your mFax account settings for the exact domain).
5. Use the subject line as your cover page message.
6. Tap Send. The fax service converts and transmits it automatically.

This approach is useful when faxing from multiple devices — the workflow is identical whether you're on iPhone, iPad, or Mac.

Supported File Formats for iPhone Faxing

The short answer: iPhone's built-in scanner produces PDFs by default, which is the ideal format for faxing. If you have an existing photo of a document (JPEG), most services handle it fine. For best results on contracts, forms, or anything with tables and columns, always convert to PDF first using our free document converter.

7 Tips for a Clear, Fax-Ready Scan

The quality of your scan determines the quality of the received fax. A blurry scan stays blurry on the other end.

1. Contrasting surface. Place white paper on a dark desk — edge detection fires more accurately.
2. Flat and wrinkle-free. Smooth out every crease before scanning. Wrinkles cast shadows that appear as dark lines in the fax.
3. Even, diffuse lighting. Natural light near a window is ideal. Avoid overhead lighting that casts a shadow from your phone.
4. Hold directly overhead. Pointing straight down prevents keystone distortion — the effect that makes text look trapezoidal.
5. Keep steady. Camera shake is the top cause of blurry scans. Rest your elbows on the desk or brace your wrists.
6. Use Auto mode. iOS's automatic timing is more consistent than manual for most users — it fires after the camera achieves focus.
7. Use Black & White for text documents. In Notes, choose the B&W filter after scanning. It increases contrast, reduces file size, and matches the standard fax grayscale format.

Troubleshooting Common Issues

Fax delivery failed:

• Double-check the fax number format, including country code (+1 for US/Canada)
• Try resending — temporary line congestion usually clears within a few minutes
• Confirm the recipient's fax machine is on and has paper

Scan looks blurry or dark:

• Wipe the camera lens with a microfiber cloth — smudges degrade image quality significantly
• Improve lighting (move near a window, avoid casting a shadow)
• In Notes, try switching to Manual mode if Auto fires before the camera fully focuses

File won't upload:

• Check your internet connection — a strong Wi-Fi signal is preferable for large files
• Verify the file isn't corrupted by opening it in Files first
• If the file exceeds 10 MB, compress it before uploading

No delivery confirmation received:

• Check your spam folder for the confirmation email
• Log into the mFax dashboard to check fax status directly
