Thinkfree Office

What Thinkfree Office is
Thinkfree Office brings a word processor, spreadsheet, and presentation tool into one online office suite for creating, viewing, and editing documents. It works with Microsoft Office DOC/DOCX, XLS/XLSX, and PPT/PPTX files, as well as ODF documents in ODT, ODS, and ODP formats. The suite supports real-time collaboration and track changes, and handles documents up to 300 MB.
Organizations can deploy Thinkfree Office on-premises, in a private cloud, or through its Hosted API. Docker and Kubernetes are supported. With self-hosting, documents, version history, and access logs stay on infrastructure managed by the customer. The Hosted API offers adapters for Google Drive, Dropbox, and Amazon S3, plus WOPI support for platforms such as SharePoint and Nextcloud; saved files are returned to the customer’s storage. White-labeling and interface customization can apply an organization’s logos and colors. A Doc2PDF option converts Word, Excel, and PowerPoint files to PDF while preserving their original layout. Thinkfree was founded in 1999 and is headquartered in Seongnam-si, South Korea. A 30-day trial is available; the MCC License starts at $900 a year.
