PDF One

PDF One — the complete PDF toolkit on your phone.

Open, view, edit and create PDFs anywhere — then do the jobs other apps make you pay for, entirely on your device. No cloud uploads, no sign-in, no waiting.

WHAT YOU CAN DO

• View & read – fast, smooth PDF rendering with thumbnails, search and jump-to-page.

• Merge & split – combine PDFs or pull out just the pages you need.

• Edit pages – reorder, rotate, delete and extract pages in seconds.

• Annotate – draw, highlight, stamp and add text (pinch to resize) right on the page.

• Scan & OCR – turn camera shots into real, text-searchable PDFs with on-device OCR — works offline.

• Fill & sign – fill forms and export the form data.

• Protect – add or remove passwords and encryption.

• Compress – shrink heavy PDFs to shareable sizes.

• Convert – images to PDF and PDF pages to images.

• Watermark – brand your documents.

• Share & print – send results anywhere or print straight from the app.

WHY PDF ONE

• On-device first: your documents never leave your phone unless you share them.

• Clean, modern design that gets out of your way.

• Built for real work: large files, long documents, no fuss.

• Free with ad support — no subscriptions.

PERMISSIONS

PDF One asks only for what it needs: storage access so it can open and save PDFs from any folder, camera for scanning, and internet for ads/support. See our privacy policy for details.
