ONLYOFFICE — Word Processors

Ascensio System SIA

ONLYOFFICE Desktop Editors is a free office suite for Windows, macOS and Linux that brings a document editor, a spreadsheet editor, a presentation editor, a PDF editor and a form creator into one app. The official pages describe it as open source under AGPLv3, working offline with local files and able to connect to services such as ONLYOFFICE, Nextcloud, ownCloud and Dropbox when you want co-editing. A separate ONLYOFFICE Documents app covers iOS and Android.

Editorial selection guide

Who is it for?

  • It suits people who write letters, reports or theses and want a word processor on their own computer: the pages list DOCX and ODT among supported text formats and offer templates.
  • It suits people who need spreadsheets or slides in XLSX, ODS, CSV, PPTX or ODP without a subscription, since the desktop page calls the editors free for personal and professional use.
  • It suits teams that already work in Nextcloud, ownCloud, Dropbox, Box or an ONLYOFFICE space and want a desktop client for those files; co-editing, comments and chat are described as cloud-connected features.
  • It suits people who prefer open-source software: the download page and the GitHub repository state the AGPLv3 license for the desktop editors and link to the source code.

Getting started

  • Download the installer for your system from the official download page: Windows .exe (online or full installers for x64, ARM64 and x86), macOS .dmg for Intel or Apple chips, or Linux .deb, .rpm, AppImage, Snap or Flatpak. The page lists version 10.0.0 for the desktop editors.
  • Open the app and, on the Home tab, click the document, spreadsheet, presentation or PDF form icon to create a file. Open the Templates tab to start from a template, or use Open local file and Browse to open an existing DOCX, XLSX or PPTX.
  • Write and format your document, then click the Save icon on the toolbar, choose a location, a name and a format such as DOCX, ODT or PDF, and confirm. Reopen the saved file once to check layout and fonts.
  • For co-editing, open the Clouds tab and connect a service. The desktop page lists ONLYOFFICE, Dropbox, Nextcloud and ownCloud, and the help center's connection guide, which covers ONLYOFFICE, says an internet connection is needed to create or connect a workspace and offers sign-up with an email address or a Google account.

Decision points

  • Decide where your files live. Local files need no connection, while co-editing, comments, built-in chat and mail merge are listed as online features that need a cloud connection.
  • Check the format your readers use. The help pages list DOCX, XLSX and PPTX plus many others, and say other formats are converted to Office Open XML when opened for editing, so keep the original file and compare the layout before sending important documents.
  • Look at the hosted plans only if you want shared rooms. On 27 October 2026 the pricing page listed a free DocSpace Startup plan (up to 3 admins, 12 rooms, 2 GB of storage) and a Business plan at $20 per admin per month; the Desktop Editors are described separately from these plans.
  • On a phone or tablet use ONLYOFFICE Documents: the App Store lists it as free with no ads or in-app purchases for iOS and iPadOS 15.0 or later, and the official site lists Android through Google Play, Huawei AppGallery, Samsung Galaxy Store and an APK.

Limits

  • The desktop page names no system requirements. The download page lists Windows 11, 10, 8.1, 8 and 7 (an ARM64 build for Windows 11 only) plus a Microsoft Store listing, macOS 10.13 or higher, and Debian 8, Ubuntu 16.04 and higher plus CentOS and RHEL packages, and links older builds for Windows XP/Vista (version 9.2.1) and macOS 10.12 or lower (a version 8 path).
  • Several things stay open. The pricing page lists paid AI add-ons for the hosted DocSpace (AI agents and tools from $0.04 per 1M tokens), and the Android page says the optional AI tools connect to providers such as OpenAI, Anthropic, Google or Ollama, but neither the desktop page nor the Android page states what AI use costs in the apps. The privacy statement does not name Desktop Editors or the mobile apps. The App Store's developer-provided labels list usage data and diagnostics as collected but not linked to you. Check what an app sends before opening sensitive files.
  • The desktop page says DOCX, XLSX and PPTX files keep their formatting, fonts, charts and styles, and the GitHub README calls the editors fully compatible with Office Open XML, but no fidelity details are given, so try complex layouts, fonts and older DOC, XLS or PPT files yourself. According to the help pages, XLS and PPT are not offered as download formats.
  • PDF editing is described on the desktop page (text, images and layout, annotation, fillable forms, password protection, digital signatures), but the help center PDF guide is only an index and its About page describes an online application, so desktop behavior is not confirmed there. Merging, splitting or compressing PDFs is not described.
  • Version numbers differ by platform on the download page (10.0.0 for desktop and iOS, 9.4.1 for Android), the Android page gives no system requirements, and the mobile apps are labeled proprietary while the desktop editors are labeled AGPLv3.

Frequently asked questions

Is ONLYOFFICE Desktop Editors free?

The desktop page says the editors are free for personal and professional use, and the download page labels them AGPLv3 with source code on GitHub. Hosted DocSpace is separate: the pricing page lists a free Startup plan and a paid Business plan. The pages do not state what the optional AI tools cost in the apps.

How do I write a Word-style document in ONLYOFFICE Desktop Editors?

Install the app, click the document icon on the Home tab, type and format the text, then click Save, pick a location, a name and a format such as DOCX, and confirm. To start from a template, open the Templates tab first. The getting-started guide in the help center describes these steps.

Can ONLYOFFICE open and save DOCX, XLSX and PPTX files?

The pages highlight DOCX, XLSX and PPTX support and also list ODT, ODS, CSV and ODP. According to the help center, many other formats such as DOC, RTF, XLS and PPT open for viewing or editing after conversion, and you can download as formats such as DOCX, ODT, XLSX, ODS, PPTX, ODP and PDF.

Does ONLYOFFICE work offline, and do I need an account?

The pages say the desktop editors work offline and open files stored on your computer. They do not say whether an account is needed for local files. Connecting to the ONLYOFFICE cloud or other services needs an internet connection, and the connection guide describes signing up with an email or Google account for a new ONLYOFFICE cloud.

Does ONLYOFFICE run on Mac, iPad and Android?

For Mac, the download page lists macOS 10.13 or higher with separate .dmg files for Intel and Apple chips. ONLYOFFICE Documents for iPhone and iPad needs iOS or iPadOS 15.0 or later according to the App Store; the listing also allows Macs with an Apple M1 chip or later on macOS 12.0 or later, but marks the app 'Designed for iPad. Not verified for macOS.' Android is offered through Google Play, Huawei AppGallery, Samsung Galaxy Store and an APK.

Is ONLYOFFICE open source, and which license applies?

The GitHub README and the download page name the GNU Affero General Public License v3.0 (AGPLv3) for the desktop editors and link the source code. The download page labels the Android and iOS apps proprietary.
