About formats

FIG is the native file format of Xfig, a free vector graphics editor for the X Window System, originally written by Supoj Sutanthavibul at the University of Texas at Austin in 1985. The format uses a plain-text structure where each graphic object is described on one or more lines with numeric parameters specifying object type, coordinates, line properties, fill attributes, and depth ordering. FIG supports compound objects (groups), polylines, polygons, splines, arcs, ellipses, text strings, and imported bitmaps, each with configurable colors, line styles, arrow heads, and area fills. Files begin with a header line declaring the format version (currently 3.2), followed by a resolution specification and the object definitions. One advantage is exceptional simplicity — the entirely text-based format is trivially parsed, generated, and manipulated by scripts, making FIG popular as an intermediate format in automated diagram generation pipelines. The rich ecosystem of conversion tools is another strength: fig2dev exports FIG files to dozens of output formats including EPS, PDF, SVG, LaTeX picture environments, PSTricks, and TikZ. This made Xfig and FIG especially popular in academic and scientific communities, where authors generate publication-quality figures that integrate seamlessly with LaTeX documents. While graphical tools have evolved since the 1980s, FIG remains in use among researchers who value its scriptability, LaTeX integration, and well-documented format stability.

SGI is the generic file extension for the Silicon Graphics Image format, also referred to by channel-specific extensions .rgb (3 channels), .rgba (4 channels), .bw (grayscale), and .int/.inta (16-bit variants). Developed by Silicon Graphics around 1986 for their IRIX operating system, the SGI format uses a 512-byte header followed by planar image data, where each color channel is stored as a complete plane rather than interleaved with other channels at each pixel. The header specifies a magic number (474), compression mode (0 for verbatim, 1 for RLE), bytes per channel (1 or 2), dimensionality (1 for scanline, 2 for image, 3 for multi-channel image), channel dimensions, pixel value range, and an 80-character image name. For RLE-compressed images, a table of offsets and lengths follows the header, allowing random access to individual scanlines without sequential decompression. Silicon Graphics workstations were the backbone of Hollywood visual effects, scientific visualization, flight simulation, and CAD/CAM industries throughout the 1990s, and the SGI format was the standard working format across these domains. One advantage is the format's robust design: the combination of scanline-addressable RLE compression, multi-channel support, 16-bit depth capability, and planar layout made it equally suitable for quick preview display and production rendering output. The format's association with the golden age of SGI-powered visual effects is another notable aspect — SGI files from this era represent production assets from landmark films and scientific visualizations. SGI images are supported by ImageMagick, GIMP, XnView, Photoshop (via plugin), and various 3D rendering and compositing applications.

Why convert FIG to SGI?

Technical illustrations in FIG format cannot be previewed in most apps. SGI conversion solves that instantly.

How do I open an SGI file?

You can open SGI files with GIMP, XnView, IrfanView, and 3D graphics workstations.

Can I convert multiple FIG files to SGI at once?

Batch conversion is supported. Upload several FIG files simultaneously and each one converts to SGI independently in a single session.

Is registration required for FIG to SGI?

No signup needed. Visit the page, upload your FIG file, convert to SGI, and download without creating an account.

Is my FIG file safe during conversion?

Uploaded FIG files are deleted immediately after conversion. SGI output files are removed from servers within 24 hours for your privacy.

How quickly does FIG to SGI conversion finish?

Most conversions complete within seconds. Larger files may take slightly longer, but cloud processing keeps it fast regardless of your device.
