All Document Reader & Editor
Overview
All Document Reader & Editor, developed by Bangladeshi Software Ltd under the Office Tool brand, is a lightweight mobile productivity utility designed to simplify office document management on Android. Rather than requiring separate enterprise apps for different file types, this package provides a unified viewer and basic editor compatible with PDF, Microsoft Word (DOC, DOCX), Microsoft Excel (XLS, XLSX), and Microsoft PowerPoint (PPT, PPTX) formats.
The application relies on dedicated on-device format parsers to render different document types smoothly. The PDF engine supports continuous page scrolling, arbitrary zoom scaling, direct page jumping, text highlighting, freehand markup, and a convenient Image-to-PDF scanner tool. The Word and PowerPoint rendering engines display text formatting, tables, and presentation slides cleanly, while the spreadsheet module provides structured viewing of XLS and XLSX workbooks with clear row-column layouts and formula visibility. It also supports image-to-PDF conversion.
A notable strength of the application is its entirely local processing architecture. The software runs completely offline without requiring mandatory account creation, cloud logins, or remote server connections, ensuring user documents remain stored solely on the device.
On Android 11 and above, the app utilizes the MANAGE_EXTERNAL_STORAGE permission to scan internal storage and organize scattered office files into categorized, sortable folders (by file name, file size, or date modified). While it lacks complex desktop-grade formatting tools and multi-user live collaboration, its fast startup speeds and low memory footprint make it a practical tool for reviewing documents on the go.
