SGI vs SVG
Ein detaillierter Vergleich von SGI Image und SVG Vector Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
SGI Image
Raster & Vector ImagesSGI (Silicon Graphics Image) is a raster image format developed by Silicon Graphics for use on their IRIX workstations. It supports both uncompressed and RLE-compressed storage with up to 4 channels including alpha.

Raster & Vector ImagesSVG is an XML-based vector image format that scales to any resolution without quality loss. It is the standard for web icons, logos, and illustrations that need to look sharp on all screen sizes.
Über SVG-DateienVorteilsvergleich
SGI Vorteile
- Historic VFX pipeline format.
- 16-bit channel support.
- RLE compression.
- ImageMagick compatibility.
SVG Vorteile
- Resolution-independent — crisp at any size, from 16px icon to 4K billboard.
- Tiny file sizes for flat graphics, logos, and UI illustrations.
- Editable with any text editor; programmatically manipulable via DOM.
- Supports interactivity, CSS styling, and JavaScript inside the image.
- Accessible — text inside SVG is readable by screen readers.
Einschränkungen
SGI Einschränkungen
- Legacy — SGI Inc. is gone.
- Superseded by OpenEXR/DPX in film.
- Niche tooling.
SVG Einschränkungen
- Not suitable for photographs or complex raster imagery.
- Uploading user-provided SVG is risky — embedded scripts are an XSS vector.
- Complex SVGs with thousands of paths render more slowly than a PNG equivalent.
- Inconsistent rendering across browsers for edge-case features (filters, gradients).
- No native concept of layers or groups for design-tool round-tripping.

Häufig gestellte Fragen
SGI (SGI Image) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose SGI when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open SGI natively. On mobile, iOS Photos and Google Photos display SGI in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our SGI to JPG or SGI to PNG converter.

Upload the SGI to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.
It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; SGI has its own niche that may favour colour depth, animation, or encoding efficiency over one or both of those. For the final web publish, test all three and measure file size plus visible quality on real content.
