RLE to FTS conversion is the process of transforming images encoded with run-length encoding (RLE) — a simple lossless compression that stores consecutive identical pixels as runs — into the FTS image container/format used by specialized imaging tools. The conversion decodes the RLE runs to raw pixel data and repackages or recompresses that data into the FTS format while preserving visual fidelity and metadata where supported.

RLE files typically use the MIME type image/rle and are commonly applied in simple image compression scenarios. FTS files, often associated with the MIME type application/fits, are widely used in astronomy and medical imaging due to their ability to store complex data and metadata. Codecs for RLE are straightforward, while FTS files may require specialized software for full access.
The FTS (.FTS) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like RLE.
While specific technical details aren't available here, FTS files generally serve the purpose of storing image effectively within their domain.
Easily convert your RLE files to FTS format using our online converter. Our tool supports seamless RLE to FTS file transformation without the need for software downloads or technical knowledge. Whether you are working with image or data files, converting RLE to FTS is now faster and more accessible than ever.
RLE is a simple compression method primarily used for basic image encoding, whereas FTS is a more advanced format often used for scientific and medical imaging. While RLE focuses on run-length encoding to reduce file size, FTS supports multiple layers and metadata for detailed file representation. Converting from RLE to FTS helps leverage these additional features for enhanced usability.
Keep source files under 50–200 MB for fastest single-file conversions; larger files are possible but take longer and need more memory.
To preserve quality, use lossless FTS output or enable alpha/palette preservation when converting RLE indexed images.
For large batches, convert files in parallel but limit concurrency to available CPU cores and memory to avoid failures.
Note format limitation: some RLE variants lose color profile or complex metadata — verify color profiles after conversion.
