No office suite to install and no account to create. View, edit and convert local files on your own device.
What you can do
- 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.
- Edit the common formats — DOCX, XLSX, PPTX and CSV, with support for common formatting.
- Skip the account — no sign-up, no login, nothing to register.
- Try the features you need while online, then use what your browser has saved offline. Opening files from links still needs a connection.
- Verify the privacy claim — read the open-source code or self-host your own copy.
How it works
- Open the editor — there is no sign-up screen in the way.
- Pick a DOCX, XLSX, PPTX or CSV file from your device.
- Read and edit it locally; the file is processed in your browser, not on a server.
- Download your changes back to your device when you are done.
Frequently asked questions
What makes this a private document editor?
Your files are opened and edited entirely inside your own browser with WebAssembly. The document is never uploaded to a server, so it stays on your device the whole time.
Do my files ever get uploaded?
No. When you open local files directly on this site, viewing, editing and conversion happen on your device without uploading your documents.
Do I need an account to keep my files private?
No account, no sign-up and no login. You open the editor and start working immediately, and there is no cloud copy of your document to manage.
Can I verify that nothing is uploaded?
Inspect the browser’s network panel while opening, editing and saving a local file. Test optional AI, remote URLs and host integrations separately; their requests are not covered by the core local-editing claim. No. When you open local files directly on this site, viewing, editing and conversion happen on your device without uploading your documents.
Does it still work without an internet connection?
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 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.
