How to Fax a Invoice from iPhone 13: Step-by-Step

    Download TigerFax

    Install TigerFax from the App Store on your iPhone 13. It's free to start — no credit card required.

    💡 Tip: TigerFax is optimized for iOS 15+ and works on all iPhones running iOS 15 or later.

    Scan your Invoice with iPhone 13

    Open TigerFax and tap the camera icon. Position your iPhone 13 about 12 inches above the Invoice and let the auto-capture detect the edges. The iPhone 13's sensor-shift OIS on the wide camera reduces camera shake during document scanning. For best results, scan in a well-lit area and let the auto-capture trigger automatically.

    Alternatively, tap the upload icon to import your Invoice from Files, iCloud Drive, or any connected cloud storage. iOS 15 on iPhone 13 supports Quick Note and improved Shortcuts integration, so you can create a shortcut to open TigerFax and start a fax directly from your home screen.

    💡 Tip: PDF format preserves Invoice formatting best. If you have a digital copy, upload it instead of scanning for the clearest result.

    Enter the recipient's fax number

    Type the recipient's fax number in the To field. For international numbers, include the country code. TigerFax automatically formats the number.
