About formats

BIN refers to MacBinary-encoded font files, a transfer format that preserves classic Macintosh file system features when moving data across platforms. Classic Mac OS stored fonts using the resource fork — a secondary data stream invisible to non-Mac systems — which meant that simply copying a Mac font to a Windows PC or Unix server would strip the actual font data entirely. MacBinary solves this by combining both the data fork and resource fork into a single flat file with a 128-byte header containing the original HFS metadata. In the font context, BIN files typically wrap TrueType suitcase fonts, PostScript Type 1 LWFN outline files, or bitmap NFNT font resources. The format was first specified in 1985 by Dennis Brothers and collaborators from the early Mac community, with MacBinary II following around 1987 and MacBinary III arriving in 1996 to support longer filenames. A key advantage is lossless preservation: every byte of the original Mac font file survives intact through email, FTP, or cross-platform file sharing, including creator and type codes that identify the font format. The single-file packaging is another practical strength — rather than dealing with separate data and resource streams, users and automated systems handle one portable container. Although modern macOS has moved away from resource forks and Mac fonts now typically ship as OTF, TTF, or DFONT files, BIN remains important for accessing archived font collections from the classic Mac era.

SUN is a raster image format associated with Sun Microsystems workstations, encompassing both the Sun Raster format (.ras) and the Sun Icon format used for window system icons and cursors on SunOS and Solaris systems. Sun Raster files, identifiable by their 0x59a66a95 magic number, store bitmap images in 1-bit monochrome, 8-bit indexed color, 24-bit BGR, or 32-bit XBGR modes, with optional run-length encoding compression and a 32-byte header. The Sun Icon subset is a simpler text-based format used for small monochrome bitmaps — window icons, cursor images, and toolbar graphics — stored as C-language data arrays that could be directly compiled into X Window and SunView applications. These icon files begin with a comment block specifying width, height, and optionally hot spot coordinates (for cursor images), followed by hexadecimal pixel values in a format readable by both the C compiler and the iconedit tool. Sun workstations running SunOS and later Solaris were foundational platforms for Unix computing, networking, and the early internet, and the SUN image formats were integral to their graphical environments. One advantage is the format's dual text/binary nature: Sun Icons are valid C source code that can be #included directly into applications, a practical approach to resource embedding that predates modern asset management systems. The Sun Raster variant's simplicity provides another strength — the 32-byte header and straightforward encoding make it one of the easiest binary image formats to parse. SUN format files are supported by ImageMagick, GIMP, XnView, and Unix image viewing tools.

Frequently Asked Questions

Why convert BIN to SUN?

SUN raster is the native format for Sun/Solaris workstations. Converting BIN creates images for Unix and Solaris imaging tools.

How to open SUN files?

SUN files open in GIMP, ImageMagick, XnView, and native viewers on Solaris and other Unix-based operating systems.

Is SUN the same as RAS?

Essentially yes — SUN and RAS both refer to the Sun Microsystems raster image format, just with different file extensions.

Does the conversion run online?

Fully online. Convertio handles BIN to SUN conversion in the cloud — no desktop software, no local processing needed.

Is there a free option?

BIN to SUN conversion is free on Convertio. No account required — open the page and convert immediately.
