On June 9, 2026, we released the first production-ready version of Euro-Office, a sovereign collaborative office suite developed and governed in Europe. With Nextcloud Hub 26 Summer, we announced the release of the Nextcloud Office Desktop app powered by Euro-Office. Today, the ready-to-use version of the app is available for download. It lets you work offline, switch between Nextcloud Hub in your browser and the app on your computer, and get the same experience on Windows, macOS and Linux.

In this article, you’ll learn about the app’s features, how to install it on Windows, macOS and Linux, and how to co-edit files with your team through Nextcloud Hub.

Free desktop office with maximum file compatibility

The Nextcloud Office Desktop app is a free and open source office suite for Windows, macOS and Linux. Featuring editors for text documents, spreadsheets, presentations, and PDFs, it offers high compatibility with Microsoft Office formats (DOCX, XLSX, PPTX) and open formats (ODT, ODS, ODP). Connect it to Nextcloud Hub to edit files with your team in real time.

The app includes the features of Nextcloud Office in your browser, plus the benefits of working on your computer:

• Work offline and keep files on your device
• Use the fonts installed on your computer
• Sign documents digitally

Work with local and online files

With the Nextcloud Office Desktop app, you can edit files locally without an internet connection. Working locally, you keep access to your files and you can keep working when you don’t have internet connection or your online tools go down. You decide which files stay on your computer and which go to the cloud.

Need to access your online files? You can connect your Nextcloud instance to the Nextcloud Office Desktop app to access all the files available to you, and edit them on your own or with your team in real time.

How to connect the Nextcloud Office Desktop app to the cloud:

1. Click “+” in the “Clouds” section in the Home tab
2. Choose “Nextcloud“ and specify the URL of your instance
3. Log in with your credentials

Once connected, choose your Nextcloud instance from the list. You can connect more than one instance to one app to have access to multiple cloud working environments.

Use your own fonts

The Nextcloud Office Desktop app uses fonts installed on your machine, including corporate fonts and default fonts from your OS, like Microsoft fonts on Windows. You can install additional custom fonts any time. No need to bother your Nextcloud admins!

Note: if your collaborators don’t have the same font, they’ll see a fallback font in their version of the file.

Digital signatures and file protection

The Nextcloud Office Desktop app lets you use digital signatures to sign your documents, spreadsheets and presentations. A signature shows who signed a file and that nobody has changed it since. Go to Protection tab and add a signature via Signature feature.

Keep in mind that you need a digital certificate to sign documents. To obtain one, you can ask your IT team at work, or get one for personal use from a trusted provider. You can find providers approved in the EU in this list.

In the Protection tab, you can also set a password for a file, or limit what others can do: comment, fill in forms, or edit with tracked changes only.
