## What is QuickInk PDF?

A little ink. All done.

QuickInk PDF helps you sign and fill PDFs on iPhone and iPad. Open a document, add the details you need, and save or share a finished copy. A simple interface with native Liquid Glass controls on iOS 26 and later keeps your document at the center.

SIGN YOUR WAY
• Draw a signature with your finger. Apple Pencil is also supported on compatible iPads.
• Import a signature image from Photos or Files.
• Remove white backgrounds from imported signature images. Preview and adjust background removal before saving.
• Create a typed signature and save signatures locally for reuse.

FILL AND FINISH
• Add text, dates, and checkmarks.
• Move and resize your annotations.
• Navigate multi-page documents and undo recent edits.
• Save a new PDF to Files or share it using the share menu.
• Keep your original PDF unchanged.

MADE FOR YOUR SCREEN
Editing tools adapt to your window: a compact floating palette on smaller screens and tools beside the document in wider windows. Light and dark appearances help keep controls clear.

THREE FREE EXPORTS. ONE SIMPLE UPGRADE.
Your first three PDF exports are free. Only successful saves or shares count toward the limit; cancelled or failed exports do not. After that, a one-time in-app purchase unlocks unlimited PDF exports. No subscription, ads, or watermarks.

Your free export count is stored on your device. Restore your unlimited-exports purchase on devices using the same Apple Account.

YOUR DOCUMENTS STAY YOURS
No app account is required. PDFs and signatures are processed on your device and are not uploaded to our servers. Saved signatures are stored on your device. Sharing happens only when you choose a destination. Purchases and restoration are handled by Apple through the App Store.
