FAQ

Questions, answered

Longer answers — file size limits, error codes, self-hosting — are in the help pages.

Can it save back into my own file, or only download a copy?

In supported browsers such as Chrome and Edge, the first save asks you to choose a file; later saves update that file. Other browsers download a copy. Use File → Download as to export another format. Autosave recovery copies are separate from the files you save.

Are my files uploaded anywhere?

No. When you open local files directly on this site, viewing, editing and conversion happen on your device without uploading your documents.

Which formats can I edit?

Word (DOCX), Excel (XLSX), PowerPoint (PPTX) and CSV. You can also view and annotate PDF files.

What happens if I close the tab or refresh the page?

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.

Does it work 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.

Do I need an account?

No account, no sign-up, no email. Open the page and edit.
