About EFTX files

The .EFTX file is a Microsoft Office Theme Effect file introduced in Office 2007. It stores visual formatting rules - such as 3D effects, line styles, shadows, and fill settings - for shapes, charts, and SmartArt graphics. These files are primarily used by Microsoft Office applications, including Word and PowerPoint, to maintain visual consistency across large documents and presentations. The biggest drawback of the .EFTX format is that it does not contain actual document text or image data; it is purely a proprietary styling container. It is not supported by standard web browsers or non-Microsoft design tools. Because it is highly specialized and lacks media content, traditional online converters will fail to process it. The best way to inspect the contents is to treat it as an Open XML package. Converting it to ZIP allows you to extract the raw XML data inside.

Convert.Guru analyzes your EFTX file, detects the exact format, and lets you read the text inside.
