ONLYOFFICE online, with nothing to install
The free office suite built around Microsoft formats, in your browser.
Included from the Personal plan

ONLYOFFICE Desktop Editors, as is
ONLYOFFICE is a free office suite built around Microsoft Office formats: Word documents (.docx), Excel workbooks (.xlsx) and PowerPoint presentations (.pptx) are its working formats, not converted ones. Its publisher adds PDF editing and forms.
In Cloud OS, ONLYOFFICE Desktop Editors, the desktop version, runs in a window of your online desktop, with its tabbed interface. Nothing to install on your computer, no updates to keep up with.
Your documents stay in your own space
You pick documents in the Files app, and they open straight in ONLYOFFICE. Once the work is done, you send them back to Files.
- Several files imported one after another, without closing the import window.
- Every file sent back arrives as a new file: the original is never overwritten.
- Your files are hosted in Québec.
ONLYOFFICE or the Cloud OS office suite?
Cloud OS also has its own office suite — Writer, Calc and Impress — which opens your files with a double-click and lets several people work on the same document. ONLYOFFICE is there when you prefer its interface, close to Microsoft Office, or when a complex document displays better in it: the simplest way to know is to try your own files in both.
Good to know
An ONLYOFFICE session is temporary: remember to send your work back to Files before closing it, since that is where it is kept. ONLYOFFICE is used from a computer; it is not offered on phones.
Frequently asked questions
- Do I need to install ONLYOFFICE to use it in Cloud OS?
- No. ONLYOFFICE Desktop Editors runs in a window of your online desktop, from the browser. There is nothing to install or update on your computer.
- Can I co-edit a document in ONLYOFFICE?
- Not in Cloud OS: each ONLYOFFICE session is your own. To write together on the same document, use the Cloud OS office suite (Writer, Calc, Impress), which supports co-editing.
- Could my original documents be overwritten?
- No. Files you send back from ONLYOFFICE to Files arrive as new files; the original stays as it was.
- Is ONLYOFFICE included in the subscription?
- Yes, from the Personal plan, like the other desktop software. There is no fee per app: each launch counts as one task in your plan's allowance.
