About formats

PICT is a metafile graphics format created by Apple Computer as the native graphics format for the Macintosh, debuting alongside the original Mac in January 1984 and remaining central to Mac OS graphics until the transition to Mac OS X. PICT files record a series of QuickDraw operation codes (opcodes) that reproduce the image when replayed through the QuickDraw graphics engine: operations for drawing lines, arcs, rectangles, rounded rectangles, ovals, polygons, regions, text strings, and pixel maps (bitmaps). This opcode-based approach means PICT files are not simply pixel grids but rather programmatic descriptions of how to draw the image, combining resolution-independent vector elements with pixel data in a unified stream. The PICT 2 revision, introduced with the Macintosh II and Color QuickDraw in 1987, extended the format to handle 24-bit color, multiple pixel depths, extended color spaces, and embedded JPEG and PackBits compressed data. PICT was integral to the Macintosh user experience: system clipboard operations (Copy/Paste), screen capture, printing, and inter-application data exchange all used PICT as the common visual representation. One advantage is historical comprehensiveness: PICT files from the classic Mac era capture both the visual output and the drawing methodology of Mac applications, preserving not just the image but the QuickDraw operations that produced it — valuable for understanding the visual computing paradigm of early Macintosh software. The format's extensive use in desktop publishing during the DTP revolution of the late 1980s provides another dimension of historical importance. PICT files are readable by macOS Preview, ImageMagick, XnView, LibreOffice, and GraphicConverter.

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 PICT to SUN?

PICT files from legacy Mac documents are inaccessible on modern systems. Converting to SUN makes them usable on Windows, macOS, and Linux.

What can I use to view SUN files?

Sun workstation software, GIMP, IrfanView, XnView, and legacy Unix image viewing applications.

What platforms are supported?

Any device with a web browser — Windows, macOS, Linux, iOS, Android, and Chrome OS. No software installation is needed for the conversion.

Do I need to pay for this converter?

Basic PICT to SUN conversions are free. Convertio offers premium tiers for heavier workloads with faster processing and priority support.

Do I need to install anything?

No — the entire conversion runs in your web browser. There is nothing to download or install on your computer or phone to convert PICT to SUN.

Will the image quality change?

Image data is transferred faithfully from PICT to SUN. The conversion itself does not degrade or enhance the original pixel information.
