PDF Reader - File Manager is a fast, offline document reader and file manager in one app. Open PDFs and Office documents instantly, browse every file on your device by category, and keep private files locked away - all without an account and without an internet connection.

DOCUMENT READER
Open and read your documents right inside the app - no other viewer required:
- PDF - smooth page-by-page reading with pinch-to-zoom.
- Word (.doc, .docx) - headings, bold/italic/underline, colours, bullet lists and tables.
- Excel (.xls, .xlsx) - every sheet laid out as a clean table.
- PowerPoint (.ppt, .pptx) - slide-by-slide titles and text.
- Plain text (.txt) - automatic character-set detection.
Documents are rendered by our own lightweight engine, so pages open quickly and stay on your device.

FILE MANAGER
See everything at a glance and take control of your storage:
- A dashboard with animated storage and memory gauges.
- Files grouped into Photos, Clips, Tracks, Documents, Packages, Archives and Downloads, each with a live count and total size.
- Full-screen photo viewer with pinch-to-zoom, plus built-in video and audio players.
- Multi-select and delete with a clear confirmation step.
- Install APK files through Android's standard installer.

SIGNATURE TOOLS
- Private Vault: protect sensitive files behind a PIN. Files are encrypted with AES (via Android's own crypto) and moved into a hidden folder; restore them any time with your PIN.
- Zip & Unzip: pack several files into a .zip archive or extract an existing archive, with a built-in guard against malicious archive paths.
- Bulk Rename: tidy up many files at once with a prefix and an automatic running number.

PRIVACY FIRST
This app does not collect any personal data, has no ads and no analytics. Everything happens on your device.
