HOW INKPDF WORKS

Tap a PDF tool from the home screen. Pick a PDF file from your phone or from recent files. The PDF tool runs on your device. Save the new PDF, share it, or open it. Rename your PDFs anytime. Search your saved PDFs.

InkPDF includes light and dark themes. The app is built for Android 8 and newer phones.

ABOUT THE OPTIONAL AI FEATURE

InkPDF includes an optional on-device AI summarizer for long text. The AI runs locally on recent flagship phones (Pixel 9, Pixel 10, Galaxy S25, Galaxy S26, and a few others) using Google's on-device Gemini Nano. The AI is fully offline — your text is never uploaded. If your phone does not support on-device AI, the app politely tells you and every other PDF tool works normally.

OUR PRIVACY PROMISE

No account. No tracking. No cloud upload. Your PDFs stay on your phone. This is not just a marketing line — it is how the app is built. Read our full privacy policy in Settings.

InkPDF is the PDF editor for people who want to merge, split, compress, sign, scan, and convert PDFs without giving their files to a stranger's server.
