ONLYOFFICE Docs

ONLYOFFICE Docs, the open-source, all-in-one alternative to Foxit PDF Editor

Edit PDFs and all kinds of office documents in one editor, with self-hosting and open-source code

Why teams look for a Foxit alternative

For teams that want one editor for documents and PDFs, open source code to inspect, or infrastructure they control, those trade-offs matter.

Foxit only edits PDFs, office documents (DOCX/XLSX/PPTX) still need separate software
AI features are Foxit's own, with no documented way to bring your own provider or local model
No self-hosted, enterprise tools exist for deploying the desktop app
Closed-source, proprietary platform

One editor for documents, sheets, slides, and PDFs
Stop switching apps. Edit DOCX, XLSX, PPTX, and PDF in the same application.
A full PDF editor, included free
Edit, annotate, and convert PDFs without a separate subscription.
AI on your terms, no add-on required
Connect OpenAI, Anthropic, DeepSeek, Gemini, or fully local models instead of paying extra for one fixed AI assistant.
Real collaboration without compromise
Real-time co-editing. Comments and version history. Role-based access control. Secure document sharing.

A built-in form builder
