Extract text from Compiz themes (EMERALD)
To convert EMERALD themes to another format, you need Emerald Theme Manager or other Settings software.
To convert other file formats to the "Compiz Window Theme" file type, you need software like Emerald Theme Manager or a similar tool.
The .emerald file is a custom window decorator theme used by Compiz Fusion. It stores visual instructions and graphical assets for rendering window borders, title bars, and buttons on Linux-based operating systems. Users typically manage these via the Emerald Theme Manager.
Because it is restricted to a legacy Linux window manager ecosystem, this format has severe limitations today. You cannot open it natively in Windows, macOS, or web browsers. The file acts as a proprietary container, meaning standard online converters usually fail to process it. Users often need to convert or extract .emerald files to recover the enclosed high-quality PNG image assets or INI configuration data for use in modern desktop environments.
The best conversion targets are standard archive formats like .TAR.GZ, or extracting the internal PNG and text files directly. While you will lose the ability to "install" the theme seamlessly, you gain full access to the raw graphic assets. This file format is difficult to open because of its niche nature. Our analysis detects the supported underlying compressed archive structure, making viewing and extracting the embedded content highly realistic.
Convert.Guru analyzes your EMERALD 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 EMERALD converter.
