What Thinkfree Office is
Thinkfree Office is an online office suite for creating, viewing, and editing word-processing documents, spreadsheets, and presentations. It handles DOC and DOCX, XLS and XLSX, PPT and PPTX, plus ODT, ODS, and ODP files. Collaborative editing, real-time collaboration, and track changes are included, with documents supported up to 300 MB. Organizations can deploy it on-premises, in a private cloud, or through a Hosted API. Self-hosting keeps documents, version history, and access logs on infrastructure the customer manages. Docker and Kubernetes are supported. Hosted API adapters include Google Drive, Dropbox, and Amazon S3, with WOPI support for SharePoint and Nextcloud. White-labeling allows logos, colors, and interface changes. Doc2PDF converts supported Word, Excel, and PowerPoint formats to PDF while preserving layout. A 30-day trial is available; the MCC License is $900 a year.
