Merge, split, annotate, protect & convert PDFs offline.

About this app

PDF Tools: Advanced is an offline-first toolkit for everyday PDF work on Android. Merge, split, annotate, watermark, compress, protect, unlock, run OCR, and convert — then save an editable project or export a finished file. Documents stay on your device unless you choose Drive or optional AI. Premium removes ads and unlocks OCR, Unlock PDF, higher AI limits, Drive upload, and multi-file gates.
