ONLYOFFICE Desktop Editors is an open-source office suite for creating, viewing, and editing documents, spreadsheets, presentations, PDF files, and fillable forms on Windows, macOS, and Linux.
ONLYOFFICE Desktop Editors is a cross-platform office suite that combines editors for text documents, spreadsheets, presentations, PDFs, and fillable forms in one desktop application. It supports common Microsoft Office and OpenDocument formats, including DOCX, ODT, XLSX, ODS, CSV, PPTX, and ODP, so users can work with files from different office environments without changing applications. The suite can create, open, and edit files stored locally without requiring a constant internet connection. ONLYOFFICE Desktop Editors also uses a tab-based interface, allowing several files to remain open in the same window while users move between writing, calculations, slides, forms, and PDF work.
The desktop suite extends beyond offline editing by connecting to supported cloud platforms for collaborative workflows, comments, reviewing, chat, and real-time co-editing when internet access is available. Users who mainly organize and convert digital books may prefer calibre, while this suite focuses on office documents, spreadsheets, presentations, forms, and PDFs. Version 9.4 adds practical editor changes such as horizontal lines in text documents, Dark Document mode for spreadsheets, new presentation themes and transitions, and updated form-filling controls. The application also supports plugins and macros for extending editor functions, while local files remain usable without maintaining a continuous cloud connection.
ONLYOFFICE Desktop Editors reduces application switching by placing document editing, spreadsheet work, presentations, PDF handling, and fillable forms inside one consistent desktop environment. Users can keep multiple files open in tabs, move between related tasks without launching separate programs, and work on local documents even when no internet connection is available. Broad support for familiar office formats helps teams exchange files with people using different productivity software, while cloud connections add real-time co-editing, reviewing, comments, and chat when collaboration is required. Built-in PDF and form tools also keep routine document workflows closer to the same interface instead of forcing users into a separate viewer or form application. Plugins and macros provide room for specialized extensions, and cross-platform availability helps organizations maintain a similar workflow across Windows, macOS, and Linux systems. The open-source AGPL licensing further supports transparent deployment for users who prefer software with publicly available source code.
Key capabilities and highlights.
The Document Editor provides tools for writing and formatting text documents, working with tables, images, shapes, headers, footers, references, and other structured content. ONLYOFFICE Desktop Editors supports popular document formats such as DOCX and ODT, making the editor useful for reports, letters, manuals, proposals, and other office documents that need full desktop editing.
The Spreadsheet Editor handles calculations, formulas, functions, charts, tables, named ranges, and other data-oriented tasks within the same suite. Version 9.4 adds Dark Document mode for sheets, giving users another viewing option while working with workbooks. Support for XLSX, ODS, and CSV helps accommodate files from different spreadsheet workflows.
The Presentation Editor supports slide design, text, images, shapes, charts, transitions, and presenter-focused workflows for creating and delivering presentations. Version 9.4 expands the creative toolkit with 25 additional design themes and 20 new slide transitions, helping users prepare varied decks without relying entirely on manually built visual styles.
The integrated PDF Editor can open and edit PDF content, add annotations and comments, insert or adjust objects, draw freehand, search documents, and use supported redaction and navigation tools. This keeps many routine PDF tasks inside ONLYOFFICE Desktop Editors rather than requiring users to switch to a separate PDF application.
Form tools support creating and completing fillable documents, including workflows that can be saved or distributed as PDF files. Version 9.4 adds recipient-related form controls, filling-status panels, and reuse of the most recently selected signature image. These changes help streamline repeated signing and form-completion tasks inside the office environment.
Users can connect the desktop application to supported cloud platforms and gain collaboration features such as real-time co-editing, reviewing, comments, and built-in chat. ONLYOFFICE Desktop Editors supports connections to services including ONLYOFFICE environments and compatible third-party platforms, combining desktop access to local resources with online teamwork when an internet connection is available.
Multiple documents can remain open within one application window through a tab-based interface. ONLYOFFICE Desktop Editors makes it easier to compare related files, copy information between documents, and move among text, spreadsheet, presentation, PDF, or form tasks without managing a large collection of separate program windows on the desktop.
The suite can be extended with plugins and macros that add specialized functions beyond the core editors. Users can manage plugins through the available plugin interface, while developers can create integrations for additional workflows. This extensibility matters when teams need language tools, automation, external services, or custom actions alongside standard office editing.
