Extract text from SHOW files
To convert your SHOW file to another format, you need Hancom Office or other Page Layout software.
To convert other file formats to the "Presentation Document" file type, you need software like Hancom Office or a similar tool.
The .show file extension primarily identifies presentation documents created by Hancom Office (formerly Thinkfree), a productivity suite widely used in South Korea. These files serve the same function as Microsoft PowerPoint (.PPTX), storing slides, text layouts, images, and animations in a compressed ZIP-based container. The core problem for international users is proprietary lock-in: .show files are not natively supported by Microsoft Office, Google Workspace, or standard web browsers. Recipients often encounter error messages when trying to open them without installing the specific Hancom viewer or suite.
To overcome this compatibility gap, the recommended workflow is converting .show documents to PPTX if you need to edit the slides in PowerPoint or Keynote. For distribution, archiving, or printing, converting to PDF ensures the layout remains fixed across all devices.
Note: A distinct variation of this file type is used by MA Lighting for their grandMA series of lighting control consoles. These are binary data files containing stage automation settings and cannot be converted into document formats like PDF; they must be opened using grandMA onPC software.
Convert.Guru analyzes your SHOW 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 SHOW converter.
