Features & Capabilities

Need to hand in several files as one, or send document photos as a single PDF? Open PDF Box.
Combine PDFs in the order you pick, pull out just the pages you need and add a password to any file.
Read, bookmark, search and preview Office files in the same app.

Merge, extract and protect
• Combine PDFs in your chosen order.
• Save selected pages or page ranges as a separate PDF.
• Lock a PDF with a password, or create an unlocked copy using a password you already know. Forgotten passwords can't be removed.

Convert photos and PDF pages
• Turn selected photos into a PDF or a DOCX document containing the photos.
• Export PDF pages as PNG or JPEG, or join them into a long JPEG image.
• Save image results from the result screen if you want to keep them.

Read and organize
• Zoom, navigate pages and search text in PDFs that contain a text layer.
• Bookmark pages and return to where you left off.
• Find imported documents by name and organize them by type, recent use and favorites.
• Rename, share, export and use Android printing.

Preview Office content
• Preview DOCX, XLSX, PPTX and TXT content and output it as PDF.
• View supported pictures linked from the DOCX document body.
• Office PDF output lays out the content again. Complex original formatting and charts are not reproduced. Pictures in XLSX or PPTX and legacy DOC, XLS and PPT files are not supported.

Work on your device
Imported files are stored as app copies; their source files are not modified. Document processing needs no account or server upload. Passwords are not saved. When you share a file, it is passed to the app you choose.

Supported scope
Up to 100 MB per file, 500 pages per PDF and 50 photos per conversion. Merge 2–50 PDFs with up to 500 pages in total. Unlock protected inputs first using their known password. Text search uses an existing text layer. OCR, camera document scanning, automatic cropping, signatures, annotations, editing existing document text and PDF compression are not supported. Requires Android 8 or later.
