How to Fax from iPhone — 3 Steps

Get the Fax.plus app from the App Store (iPhone) or Google Play (Android). Free to download. Create a free account — 10 pages included, no credit card.
Add Your Document
Tap "New Fax". Upload a PDF from your Files, attach a photo, or use the built-in camera scanner to photograph a paper document. The app straightens and enhances it automatically.

How to Scan and Fax a Paper Document from iPhone
Don't have a digital file? No problem. Fax.plus includes a built-in document scanner:
- Open Fax.plus → tap New Fax
- Tap the camera icon (not the attachment icon)
- Hold your phone over the paper — the app auto-detects the document edges
- Tap the shutter button. The app crops, straightens, and enhances the scan automatically
- Scan additional pages if needed, then tap Done
- Enter the fax number and tap Send
The scanning quality is comparable to a dedicated scanner app. For best results: use good lighting, place the document on a dark background, and hold your phone directly above it.
How to Fax a PDF from iPhone
If you already have a PDF (from email, Safari, or another app):
- From Files app: Open Fax.plus → New Fax → attachment icon → Choose File → navigate to your PDF
- From email: Long-press the PDF attachment → Share → Fax.plus
- From Safari: Open the PDF → Share button → Fax.plus
- From iCloud Drive: Fax.plus → New Fax → attachment icon → iCloud Drive

iPhone Fax Tips & Tricks
- International faxes: Always include the full country code (e.g., +44 for UK, +33 for France). Skip spaces and dashes.
- Cover page: The subject line of your fax becomes the cover page title. Keep it clear and professional.
- File size: PDFs over 20MB may fail. Compress large PDFs with Apple's built-in PDF compression before sending.
- Multiple pages: You can scan multiple pages in one session. Tap the + icon after each page to add more.
- Delivery confirmation: If you don't get a delivery confirmation within 10 minutes, check the fax number — a wrong digit is the most common cause.
