SUN to FTS conversion is the process of transforming an image stored in the SUN raster format (commonly produced by legacy SUN/NeWS or SunOS tooling) into the FTS image container (FTS), which may be used for specialized image workflows or compatibility with software that requires the FTS layout. This conversion remaps pixel data, headers, and metadata so the visual content and essential attributes are preserved in the target FTS format for viewing, processing, or archival.

SUN files generally use the MIME type application/x-sun, mainly used for raw image or data storage. FTS files typically carry the MIME type application/x-fts and are used in specialized applications requiring structured file formats. Both formats may support various codecs depending on the source and target application.
The FTS (.FTS) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like SUN.
While specific technical details aren't available here, FTS files generally serve the purpose of storing image effectively within their domain.
Convert your SUN files to FTS format effortlessly using our online SUN to FTS converter. Designed for speed and accuracy, our tool supports seamless conversion without the need for complicated software installations.
SUN files are typically raw data containers, while FTS files are more structured and optimized for specific software use. FTS format offers enhanced support for metadata and indexing compared to the simpler SUN format. Choosing FTS can improve efficiency in data handling over SUN files.
Keep individual SUN source files under 100–250MB for smooth browser-based conversion; very large images may require desktop tools or chunked processing.
To preserve quality, convert 8-bit palette SUN images to 24-bit RGB FTS rather than re-quantizing; avoid lossy compression when exact colors matter.
For batch conversion, group files by resolution and color depth to minimize processing parameters changes and speed up throughput.
Be aware that some SUN-specific header fields or uncommon bit-packed encodings may not map perfectly to FTS; test a sample file first and inspect metadata after conversion.

If you need transparency or multiple frames, confirm the target FTS variant supports those features—otherwise export to an intermediary (e.g., TIFF) before finalizing.
