No office suite to install and no account to create. View, edit and convert local files on your own device.
How it works
- Click Open the editor — no sign up, login or account step.
- Drag in a DOCX, XLSX, PPTX or CSV file from your device, or start a new blank document.
- Edit it in your browser with the OnlyOffice engine — nothing is uploaded.
- Download the file in its original format, or export it to PDF, TXT, HTML or CSV.
Why people use it
- No sign up, no login, no subscription — open the page and start editing.
- Local files are opened, edited and converted on your device, without a document-processing server. The source code is public for inspection and self-hosting.
- All the common formats — Word (DOCX), Excel (XLSX), PowerPoint (PPTX) and CSV.
- Try the features you need while online, then use what your browser has saved offline. Opening files from links still needs a connection.
- Open source — audit it or self-host it yourself.
Frequently asked questions
Do I need to sign up or create an account?
No. There is no sign up, no login and no account of any kind. Open the editor and start editing immediately.
Are my files uploaded to a server?
No. When you open local files directly on this site, viewing, editing and conversion happen on your device without uploading your documents.
Is it really free?
Yes. It is free and open source under the AGPL-3.0 license. You can also self-host it from the source code on GitHub.
Can I use it offline?
Yes, with some preparation. Open the files you need online and try editing and exporting, then disconnect to check they work. Clearing browser data may require reconnecting. Files opened from links need a connection.
What file formats can I edit?
Word (DOCX), Excel (XLSX), PowerPoint (PPTX) and CSV. You can also export to PDF, TXT, HTML or CSV.
Is there a catch — a paywall or a premium tier?
No. It is genuinely free and open source under AGPL-3.0, with no paywall and no premium tier.
Can I use it on my phone?
Yes. It runs in any modern mobile browser, so you can edit on a phone or tablet without installing an app.
What remains after I close the tab?
With autosave enabled, you can recover your work in the same browser. Copies stay for 7 days after the last edit or open and can be managed at /history (Saved documents). Browser data can be cleared, so save important changes to a file.
