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.
