Private PDF Signer

Private PDF Signer lets you open a PDF, add a visual signature, text, or date, and export a signed copy from your iPhone or iPad. Open PDFs from Files, or share a PDF into the app from Mail and other apps. Save signature images from Photos or Files for reuse later. The app works locally on device. No account is required, and documents are not uploaded by the app. Important: signatures created in this app are visual marks on a PDF. The app does not provide notarization, identity verification, or cryptographic digital-signature certificates.
