Core local editing: No registration wall stands between you and your document. Everything runs locally in your browser with WebAssembly, so there is no account to create because there is no server storing your files in the first place. You open a file, edit it, and download it again — that is the whole flow.
Core local editing: It is a full editor, not a stripped-down preview: powered by the OnlyOffice engine, your fonts, tables, formulas and layout stay intact. And because your files never leave your device, skipping the account also means skipping the usual trade of your data for access.
What you can do
- Start with no account — no sign-up, no login, no email or phone number.
- Edit the common formats — DOCX, XLSX, PPTX and CSV, with full formatting preserved.
- Core local editing: Keep files on-device — 100% client-side; your documents are never uploaded.
- Cached editing resources can work offline; remote file URLs need a connection.
- Stay free — open source under AGPL-3.0, with no paywall to unlock.
How it works
- Open the editor — no sign-up screen appears.
- Choose a DOCX, XLSX, PPTX or CSV file from your device.
- Edit it directly in your browser; the file is processed locally, not on a server.
- Download the finished file back to your device.
Frequently asked questions
Can I edit documents without creating an account?
Yes. There is no account, no sign-up and no login. You open the editor and can start editing your DOCX, XLSX, PPTX or CSV file right away.
Do I need to give an email address?
No. Because there is no registration step, you are never asked for an email address, a phone number or any personal details.
Where are my files saved if there is no account?
Core local editing: Your files stay on your own device. Editing happens locally in your browser with WebAssembly, and you download the result back to your computer — nothing is uploaded.
Is it free without an account?
Yes. It is free and open source under the AGPL-3.0 license, with no paywall and no account required to unlock features.
Can I use it offline without signing in?
Offline editing requires the application, editor engine, converter and relevant fonts and format resources to be cached and retained by your browser. One visit or PWA installation does not guarantee this. Remote file URLs require a network connection.
What remains after I close the tab?
When autosave is enabled, recovery copies are kept in this browser’s IndexedDB for 7 days after the last edit or open. Closing a tab does not remove them. You can delete copies or disable autosave at /history. Browser storage can be cleared or evicted, and edits not yet autosaved may be lost; recovery is not a replacement for saving your file.
Is a built-in AI assistant available?
The built-in AI assistant is unfinished and is not a released feature. An embedding host can receive exported files and upload them according to its own policy.
