Need to edit a document, spreadsheet, or presentation on a Windows PC, including when offline? ONLYOFFICE brings those editors together and supports collaborative work through its connected services.
Edit documents, sheets, and slides
Use the document editor for written work, the spreadsheet editor for tables and calculations, and the presentation editor for slides. ONLYOFFICE supports common Office formats such as DOCX, XLSX, and PPTX, so those files can be opened and edited in the corresponding editor.
The suite also includes PDF tools for reading and editing PDFs, importing or exporting PDF files, and creating fillable PDF forms. For text-based documents, conversion to Markdown or HTML is available.
Work on files without an internet connection
The Windows desktop editors can open and edit files offline. This suits work kept on the PC, including drafting a document or changing a spreadsheet before sharing it. Online sharing and collaboration are available through ONLYOFFICE DocSpace or a supported platform integration.
Review changes with collaborators
When documents are shared through a connected collaboration service, collaborators can work together on the same file. Editing modes support co-editing at the character or paragraph level, while review tools provide tracked changes and document comparison.
- Leave comments and mention collaborators.
- Use built-in chat or connect through Telegram.
- Make audio or video calls through Jitsi or Rainbow.
