SUN file format information

Extension	SUN
Full Name	SUN Rasterfile
Type	Image
Mime Type	application/octet-stream
Format	Binary

The SUN file format, developed by Sun Microsystems, is an image file format used to store raster images in a simple binary format. SUN files are primarily used for high-quality graphics; however, due to the uncompressed nature of the format, SUN files can become very large at higher resolutions.

The format stores image pixel data as a sequence of bytes and supports monochrome and full color image formats in an uncompressed form, meaning there is no loss in quality when saving an image in the SUN format.

SUN files are a legacy file format that can be opened with certain image editing applications that still support this format; alternatively, we have a set of SUN image conversion tools designed to convert SUN files to other, more modern formats, such as PNG.

SUN Converter Capabilities

Our SUN converter can both convert from and to SUN files, and our developers are working to improve our SUN conversion tools in future versions.
