HOW TO CONVERT PSD → SGI
Provide the PSD
Click or drag to upload. We accept a single PSD file per job, with an optional queue of additional images for batch mode.
Encode to SGI
The conversion decodes the PSD, resolves the colour space to sRGB and writes the SGI container around the pixel data.
Save the SGI
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all SGI outputs is produced instead.
Here is the short version — PSD is Adobe Photoshop's native editing file with full layer, mask and channel support. Hence the need for SGI. Turn a PSD image into a SGI in seconds. The two formats share the same raster DNA so the visible quality is very close; what changes is how the file is packaged, which matters for browsers, editors and CMS uploaders. KaijuConverter runs the conversion server-side and deletes both files within two hours. In practice PSD is Adobe Photoshop's native editing file with full layer, mask and channel support. On the other end, SGI is a raster image format with its own balance of compression, colour depth, and software support.
Why convert PSD to SGI
The real reason to move from PSD to SGI is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking SGI solves those edge cases at the cost of a short conversion step.

PSD vs SGI — Strengths and limitations
What each format does best, and where it falls short.
PSD Strengths
- Preserves every Photoshop feature: layers, masks, adjustments, smart objects, text, effects, styles.
- Backward-compatible — files from 1990 still open in modern Photoshop.
- Industry-standard handoff format between designers, agencies, and prepress.
- Supports 32-bit HDR, CMYK, Lab, Duotone, and spot colors for professional print work.
- Rich metadata, color profiles, and printing instructions survive round-trips.
Limitations
- Proprietary — full fidelity only in Adobe tools; other apps approximate.
- File sizes are enormous (hundreds of MB is common for complex documents).
- Not a web format — browsers cannot display PSD natively.
SGI Strengths
- Historic VFX pipeline format.
- 16-bit channel support.
- RLE compression.
- ImageMagick compatibility.
Limitations
- Legacy — SGI Inc. is gone.
- Superseded by OpenEXR/DPX in film.
- Niche tooling.
Quality & Compatibility
PSD-to-SGI conversion does not change the visible content. Quality is capped by the PSD decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original PSD alongside the SGI copy.
Tips for Best Results
- Large PSD files may look identical to small SGI files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export SGI at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related PSD images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both PSD and SGI are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If SGI is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded PSD exactly, but cannot recover detail that PSD had already compressed away.
Often yes, especially when SGI is lossless. PSD tuned for efficient web delivery will usually produce smaller files than SGI's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
Adobe Photoshop Document
Source formatPSD is the native file format for Adobe Photoshop, storing layered image data, masks, color spaces, and editing metadata. Converting PSD flattens layers into a single composite image.
SGI Image
Target formatSGI (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.
Common Use Cases
Share across platforms
Send SGI files to anyone without worrying about whether they have the right software for PSD.
Embed in documents
Drop SGI output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
SGI often produces smaller files than PSD for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
