Sun 32-bit raster file
File type: Bitmap image file
The .im32 file extension identifies a 32-bit raster image file associated with SunOS, Sun's Unix operating system.
The file contains bitmap image data for a 32-bit raster graphic.
File type category:
Bitmap image file
Date updated: September 30, 2026
The Sun 32-bit raster file was used with SunOS, the Unix operating system developed by Sun Microsystems. It belongs to the bitmap image file category.
The format stores raster graphic image data. It is obsolete and no longer in common use, and modern software may not support it directly.
Open an .im32 file with a Unix image utility that specifically supports the Sun 32-bit raster format. Because the format is obsolete, current image viewers may not recognize it.
If the file does not open on a modern Linux or Unix system, an older SunOS environment or format-specific conversion tool may be required.
Conversion is practical only with software that can read this specific Sun 32-bit raster format. If such software is available, export the image to a currently supported bitmap format.
There is no dependable generic conversion method for an .im32 file when the original format support is unavailable.
