Online Office

An on-the-go solution for word processing and more

Have you ever been on your way to a meeting and noticed a typo in the presentation that you’re about to give? With Online Office, a new service being developed by GMX, you can open, edit and create files on the go so that you never have to show up to work unprepared again. With tools to open and edit documents, create spreadsheets and make online presentations integrated directly into your GMX mailbox, you can get the job done no matter where you are. Best of all, Online Office is completely free and compatible with the web browsers and file types that you already use.

What is Online Office?

Online Office is an exciting new feature from GMX that grants you access to a free word processor, spreadsheets and a presentation maker all within your mailbox. Give it a spin to experience the future of cloud computing today!

Opening, editing and creating files on the go is a breeze with Online Office. There are no licensing fees and no installation is necessary, making our free word processor a convenient and affordable alternative to Microsoft Office. Thanks to its compatibility with many file formats, you can use Online Office to open Excel spreadsheets or even edit a PowerPoint online, all from your browser of choice.

At GMX, we value your privacy and use comprehensive data protection to secure the documents that you open, edit and create. All files are stored in GMX Cloud, where you have 2GB of free online storage waiting for you.

How to integrate Online Office into your workflow

It can be a drag to try out a new word processor. What if it can’t open the files that you need, or makes you waste precious time restarting your computer? With Online Office, no installations or updates are necessary, and nearly every file type is supported. And have we mentioned that it’s completely free?

To access Online Office, simply log in to your GMX account as usual. Then, navigate to Online Office. You’ll see it in the main navigation bar at the top of the screen, next to Cloud.

Users can open, create and edit files on our online platform in standard Microsoft Office, OpenOffice and LibreOffice formats. For text processing, .doc, .docx, .odt, .rtf and .txt file formats are supported. For spreadsheets, .xls, .xslx and .ods are supported. For presentations, .ppt, .pptx and .odp are supported.

All Online Office files are stored in GMX Cloud, a secure platform with plenty of space for all of your most important documents—there’s room for 300,000 files, to be exact. To open and edit a file from your computer, you can either first upload it to the Cloud, or open it directly in Online Office. Email attachments must be saved in the Cloud prior to being opened or edited with Online Office.
