PHOTOSHOP Document to SUN conversion is the process of transforming a .PSD file—Adobe Photoshop's layered image format—into a SUN (.sun) file, a raster graphics format used historically for Sun Microsystems systems and some legacy imaging workflows. This conversion flattens or maps PSD layers, channels, and color profiles into the SUN raster representation so the image can be opened by software that supports the SUN format.

Drag your .PSD file from your computer or use the browse function.
Confirm .sun as the selected destination format.
Click "Convert" and download your converted .SUN file once ready.
The PSD format’s MIME type is image/vnd.adobe.photoshop, commonly used in professional graphic design for storing layered images. SUN files have a MIME type of application/x-sun-raster, typically used in Unix-based systems for raster graphics. PSD files support complex layering and many color modes, whereas SUN files are generally encoded with simple raster codecs suitable for fast rendering.
The SUN (.SUN) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like PHOTOSHOP Document.
While specific technical details aren't available here, SUN files generally serve the purpose of storing other effectively within their domain.
Easily convert your PHOTOSHOP Document (PSD) files to SUN format using our efficient online PSD to SUN converter. Whether you need the conversion for compatibility, optimization, or archiving, our tool ensures a smooth and reliable process without any software downloads.
PHOTOSHOP Document (PSD) files are layered image files primarily used for advanced graphic editing and retain extensive data. In contrast, SUN files are optimized for specific applications requiring a streamlined format with less complexity. While PSD offers flexibility in editing, SUN focuses on efficient storage and compatibility within targeted environments.
Keep PSD files under 200–500MB for reliable web-based conversions; very large documents may require local tools or flattening first.
To preserve visual fidelity, convert with the same color profile (sRGB or Adobe RGB) and flatten only when necessary to avoid layer compositing differences.
For batch conversion, prepare PSDs with consistent dimensions and color modes; command-line or dedicated batch tools handle large sets more reliably than web converters.
Note format limitations: SUN is a legacy raster format with simple channel support—complex Photoshop features like adjustment layers, smart objects, layer styles, and vector shapes may be rasterized or lost.
