Office Studio

About

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.
