Office Studio - Offline PDF, Docs, Sheets and Slides editor

Offline PDF, spreadsheet, document and slides editor. Everything runs locally: no server, no cloud, no telemetry, no accounts.

Easily view, edit, and save Microsoft Word, Excel, and PowerPoint files without installing Microsoft Office. Office Studio is a complete office suite that runs entirely on your computer. Edit PDFs, spreadsheets, documents, and slide decks in one place — with nothing uploaded, no account to create, and no network connection required. Your files never leave your device. PDF — merge, reorder and rotate pages, edit text on the page, fill and flatten forms, redact, add shapes and signatures, and password-protect. Spreadsheet — a full grid with formulas, charts, pivot tables, sorting, filtering and conditional formatting; opens and saves .xlsx and .csv. Document — a rich word processor that reads and writes .docx: styles, tables, images, equations, track changes, mail-merge, grammar and spelling, and a built-in thesaurus. Slides — build and present decks with themes, shapes, SmartArt, transitions, speaker notes and a presenter view; reads and writes .pptx. Private by design. There is no server, no cloud, no telemetry, and no sign-in. Everything happens in your browser, on your machine. You can verify it yourself: open DevTools, watch the Network tab, and use the app — nothing about your content is ever sent. (The one exception is an optional, click-only license check for the Pro upgrade.) Free stays completely free. A 14-day Pro trial unlocks the professional tools (batch PDF, redaction, pivot tables, macros, track changes, mail-merge, premium slide themes and more); when it ends, the app reverts to the free tier — no lockout of anything you created. Works offline. Opens Microsoft Office formats (.docx, .xlsx, .pptx) and PDFs. If you’re finding this tool helpful, check out our other extensions!
