About formats

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.

DOCM is a macro-enabled document format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. Structurally identical to DOCX — a ZIP archive containing XML parts for document content, styles, themes, and media — DOCM adds the ability to store and execute VBA (Visual Basic for Applications) macro code within the document. The separate .docm extension was a deliberate security measure: users and administrators can distinguish macro-containing files by extension alone, and group policies can restrict macro-enabled formats while allowing standard DOCX documents to open freely. DOCM files store VBA projects in a vbaProject.bin stream within the ZIP package alongside the same XML document content used by DOCX. Macros in Word documents enable automated report generation, custom form processing, document assembly from templates and data sources, and integration with external systems. One advantage is document-level automation — a DOCM file can include routines that populate content from databases, enforce formatting rules, validate fields before submission, or generate derivative documents automatically. The format preserves full compatibility with the OOXML specification, so all standard Word features — styles, tracked changes, comments, embedded media — work identically to DOCX. DOCM is supported by Microsoft Word on Windows and macOS, with macro execution limited to the desktop application.

Frequently Asked Questions

Why convert SGI to DOCM?

SGI images from IRIX workstations have limited support on mainstream systems. Converting to DOCM enables viewing and editing on any device.

What can I use to view DOCM files?

Microsoft Word (macro-enabled), LibreOffice Writer, WPS Office, and compatible Office suites.

Can I convert multiple SGI files at once?

Yes — Convertio supports batch uploads. Queue several SGI files and convert them all to DOCM in one session, saving time on repetitive tasks.

Is it safe to upload SGI files?

Convertio deletes uploaded files immediately after conversion. Converted output is removed from servers within 24 hours for your privacy.

How long does SGI to DOCM conversion take?

Most conversions finish in seconds. Processing time depends on file size and server load, but standard images are typically converted almost instantly.

Does this work on my phone?

Yes — the Convertio converter runs in any mobile browser. Upload your SGI file, pick DOCM, and download the result directly on your phone.
