About this app

PDFnik brings a complete PDF toolkit to Android.

View and edit documents directly on your device. Add text, comments, highlights, drawings, and signatures; move objects, organize pages, and save a separate copy without changing the original.

Use the same secure advanced tools available in PDFnik for iOS:
• merge, split, compress, and organize PDFs;
• Russian and English OCR;
• PDF to JPG/PNG and images to PDF;
• watermarks and page numbers;
• add or remove a password;
• permanent area redaction;
• text and visual comparison;
• document security reports.

Text search, zoom, rotation, Undo/Redo, and draft autosave work on every supported Android version. Export preserves the original PDF text layer, links, and existing annotations.

Viewing and editing run locally. For a selected server operation, files are sent over an encrypted connection to a temporary PDFnik session in Germany, EU. A session expires after 15 minutes of inactivity and always within 2 hours; the cleanup system then physically removes its files. PDFnik does not send documents to third-party AI, OCR, or PDF providers.

An account is optional. It lets you use account limits and subscriptions across devices. The app includes registration, password recovery and changes, email verification, subscription cancellation, and full account deletion.

Switch instantly between English, Español, Português, हिन्दी, and Русский independently of the device language.
