Tengri Office

Bring everyday documents into one private workspace. Open PDF, DOCX, XLSX, CSV/TSV and PPTX files, make supported edits, and export independent copies.

READ COMFORTABLY
PDF and Word files open in a clean viewer. Tap Edit when you need writing tools. Scroll pages continuously, find text and use touch zoom.

WORK WITH PDFs
Add text annotations, highlights, drawings and visible signatures. Edit supported ungrouped original text and images, insert pictures, and position page objects. Organize pages, merge or extract documents, add visible watermarks and page numbers, and export page images.

Create and fill supported interactive forms. Apply marked-area redaction to exported copies. Protect a PDF copy with AES-256 encryption and permissions, or use owner authentication to create an explicitly unencrypted editable copy. Local originals and drafts retain their source contents.

SCAN AND RECOGNIZE TEXT
Import photos or use the system camera. Review detected edges or adjust corners manually, correct perspective, rotate pages and apply scan filters. Bundled offline OCR supports English and Hindi + English. Review recognized text and create searchable PDFs, TXT or Word files. Recognition accuracy varies.

EDIT OFFICE FILES
Word: edit paragraph text and common formatting, preserve mixed text styles, and add or remove paragraphs. Tables and common images are previewed.

Spreadsheets: edit cells and ranges, calculate supported formulas, paste tables, freeze panes, resize rows and columns, find and replace values, sort values and add worksheets. Export XLSX, CSV or paginated worksheet PDFs.

Presentations: add, duplicate, reorder or remove slides. Edit text and common mixed styles, position objects, insert shapes and images, and present basic previews. Pinch zoom and pan without moving the selected object.

READ AND ORGANIZE
Read DRM-free EPUB and MOBI books with search, themes, bookmarks and local notes. Find documents with search and format filters, star favorites, organize collections and recover files from Trash.

LOCAL PROCESSING
No account, advertising, analytics or app-server document uploads. Processing and saved drafts stay on the device. Choose an Android save or share destination for exported copies. Keep independent exports before clearing app data or uninstalling.

COMPATIBILITY
Common document features are supported; complete Office fidelity is not claimed. Original PDF editing has font and grouped-content limits and does not reflow paragraphs. Ordinary highlighting or object removal is not redaction. Redacted complex pages may flatten at 200 dpi and lose selectable text. Complex Office layouts, charts, groups, animations and advanced formatting may preview differently. Legacy DOC/PPT/XLS, macros, collaboration and certificate-based digital signing are unsupported. Input files are limited to 25 MB. Android System WebView 125+ is required.
