Extract text from CPTX files
To convert your CPTX file to another format, you need Adobe Captivate or other Page Layout software.
To convert other file formats to the "E-Learning Project" file type, you need software like Adobe Captivate or a similar tool.
A .CPTX file is the primary project source format created by Adobe Captivate, an industry-standard e-learning authoring tool. These files serve as the master container for interactive courses, software simulations, and quizzes, storing raw assets like audio, video, slide logic, and branching scenarios.
The biggest obstacle with .CPTX files is their strictly proprietary nature. You cannot view or play a .CPTX file directly in a web browser or media player; it must be opened within the expensive, licensed Adobe Captivate environment to be rendered. Furthermore, version compatibility is notoriously strict - newer versions of Captivate often struggle to open legacy projects without corruption, and files saved in newer versions are generally backward-incompatible.
For distribution or review, these files must be converted. To share the course with learners, the project should be published (converted) to HTML5 (for web hosting) or SCORM/xAPI packages (for LMS upload). If you need a passive video format for YouTube or archival, the content must be rendered to MP4. For text-based review or storyboarding, exporting to DOCX (Word) is the standard workflow. If you simply need to recover a lost image or audio clip from a corrupt project, the .CPTX container is actually a renamed ZIP archive; changing the extension allows you to extract raw media assets manually.
Convert.Guru analyzes your CPTX file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CPTX converter.
