ONLYOFFICE Online Editors

View and edit your office document, spreadsheet and presentation files on line, directly on your web browser and from anywhere in the world, using your private, multi-user wölkli installation.

The online office feature of wölkli Cloud Storage uses ONLYOFFICE Online Editors, which work right in your browser and constantly exchange data with the server. This makes ONLYOFFICE more performant than other similar products, as it delivers a much more rapid editing process. ONLYOFFICE supports major document, spreadsheet and presentation file formats (i.e. DOCX, XLSX, PPTX, TXT and CSV) and it works in any modern browser, without the need for additional software or plug-ins. Multiple editors can work simultaneously, securely and in real time on any supported type of office files, bringing on-line office collaboration to the next level. The communication between your device and our servers is encrypted using the SSL protocol and your files can be stored encrypted on our secure cloud storage servers. This allows you to keep your senstive private or corporate data under your own control, while increasing productivity.
