Thinkfree Office
Seongnam-si, Gyeonggi-do, Republic of Korea
What it is
Thinkfree Office combines online word processing, spreadsheets, and presentations for creating, viewing, and editing documents. It supports DOC/DOCX, XLS/XLSX, PPT/PPTX, and ODT, ODS, and ODP files. Collaborative editing, real-time collaboration, and track changes are included, with a maximum document size of 300 MB. Organizations can deploy it on-premises, in a private cloud, or through a Hosted API, with Docker and Kubernetes support. Self-hosting keeps documents, version history, and access logs on infrastructure the customer manages. Hosted API adapters cover Google Drive, Dropbox, and Amazon S3, with WOPI support for SharePoint and Nextcloud; saved files are returned to customer storage. White-labeling and interface customization support organizational branding. Doc2PDF converts Word, Excel, and PowerPoint files to PDF while preserving layout. The Trial License is free for 30 days. The MCC License costs $900 a year, billed by active browser tabs with a minimum of 30. Thinkfree was founded in 1999 and is headquartered in Seongnam-si, Republic of Korea.
