How to Fax a PDF from iPhone 16: Step-by-Step

  1. 1

    Download TigerFax

    Install TigerFax from the App Store on your iPhone 16. It's free to start — no credit card required.

    💡 Tip: TigerFax is optimized for iOS 18 and works on all iPhones running iOS 15 or later.

    Scan your PDF with iPhone 16

    Open TigerFax and tap the camera icon. Position your iPhone 16 about 12 inches above the PDF and let the auto-capture detect the edges. The iPhone 16's 48MP main camera captures document text at exceptional resolution. Use the Camera Control button on the side to trigger a scan hands-free — perfect when you need both hands to hold a document flat.

    💡 Tip: Your PDF may have multiple pages — TigerFax lets you scan each page in sequence before sending.

  3. 3

    Alternatively, tap the upload icon to import your PDF from Files, iCloud Drive, or any connected cloud storage. iOS 18 on iPhone 16 supports enhanced Files app integration. You can import documents from iCloud Drive, Dropbox, Google Drive, or any connected storage directly into TigerFax.
