Convert Raster images and data (SUN) online for free
The converter easily converts your SUN files to various formats - free and online. No XnView or or other Raster Image software needed.
The converter also works in reverse, so you can convert other "Unix Bitmap" formats to SUN without using software like XnView or a similar tool.
The .sun extension is a chameleon in the digital world, representing two completely different file types depending on its origin. Most commonly, it is a Sun Raster graphic, a legacy bitmap format native to Sun Microsystems' Unix platforms (Solaris). These files use a simple structure (often RLE-compressed) that modern operating systems like Windows and macOS do not natively display. They are typically unoptimized for the web, lacking the compression efficiency of modern formats. Users often struggle to view them without specialized tools like GIMP or XnView.
Alternatively, a .sun file may be a financial data export from Infor SunSystems, an accounting solution used by enterprises. In this context, the file contains ledger transactions or budget data. The friction here is proprietary lock-in; users cannot simply double-click to view the data in Microsoft Excel.

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 SUN converter.
