About this app
Turn paper documents and photos into clear PDF files with Keen PDF.
SCAN DOCUMENTS
Capture multiple pages with your camera, review every page, adjust the crop, rotate, reorder, retake, or remove pages, then create one PDF.
IMAGES TO PDF
Choose one or more images with Android's system photo picker. Arrange and crop them before creating a multi-page PDF.
OFFLINE OCR
Extract text directly on your device with bundled OCR models for Latin, Chinese, Japanese, Korean, and Devanagari scripts. Edit, copy, or share the recognized text. Images and recognized text are not uploaded.
MERGE AND SPLIT PDFS
Combine multiple PDF files in your chosen order. Extract selected pages into a new PDF, or split every page into a separate file without changing the original document.
PREVIEW AND MANAGE RESULTS
Open generated PDFs page by page, rename them, share them through Android, or delete them after confirmation. Your output files are saved in Downloads/Keen PDF.
BUILT FOR PRIVACY
Keen PDF has no account, no advertising SDK, and no product analytics. Document processing happens on your device. The app only accesses files you select and requests camera access only when you start scanning.
SUPPORTED APP LANGUAGES
English, Spanish, Brazilian Portuguese, French, German, Italian, Russian, Turkish, Indonesian, Vietnamese, Arabic, Hindi, Japanese, Korean, Simplified Chinese, and Traditional Chinese.
Keen PDF focuses on practical scanning, offline text recognition, and essential PDF tools without cloud accounts or unnecessary complexity.
