Convert ZMG to another file type
To convert ZMG images to another format, you need Zeta3D or other Raster Image software.
Convert a file to ZMG
To convert other file formats to the "3D Height Map" file type, you need software like Zeta3D or a similar tool.
About ZMG files
The .ZMG extension represents a specialized imaging format primarily used by Zeta Instruments (acquired by KLA Corporation) for their Zeta3D optical profilers. Unlike standard photos, these files contain precise 3D surface topography data, storing Z-axis height measurements for every pixel to analyze roughness and step heights on microscopic samples.
Users frequently face difficulties because .ZMG files are proprietary and completely incompatible with standard viewers like Adobe Photoshop or web browsers. They often act as a "black box," locking valuable metrology data inside the instrument's ecosystem. A secondary, unrelated use of this extension is for ALI Corp satellite receiver firmware; these are ZIMG compressed binaries that cannot be viewed as images and often confuse users trying to update set-top boxes.
For scientific users, the goal is typically converting the proprietary map into a universal format. The best targets are TIFF (16-bit grayscale for height maps), CSV (for raw data analysis in Microsoft Excel), or PDF for non-interactive reports. For firmware users, the objective is usually decompressing the ZIMG archive into a raw BIN file for flashing or hex editing.
Convert.Guru analyzes your ZMG file, detects the exact format, and lets you read the text inside.
If you want to convert ZMG file to , you can use Zeta3D or similar software from the "Microscopy Surface Topography" category. In the File menu, look for Save As… or Export….
To convert files to ZMG, try Zeta3D or another comparable tool in the "Microscopy Surface Topography" category.
The ZMG Converter Story
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 ZMG converter.
