SIXEL to JBG conversion is the process of transforming raster graphics encoded in the SIXEL terminal graphics format into the JBG (Joint Bi-level Group) bi-level image format. This conversion decodes SIXEL's palette and run-length encoded pixel data, then remaps and thresholds or dither downs to the 1-bit-per-pixel structure used by JBG for compact black-and-white archival or device-specific use.

SIXEL images typically use the mime type image/sixel and are used in terminal graphics and legacy applications. JBG, with mime type image/jbg, is commonly used for compressed bi-level images in document storage and fax transmission. Both formats rely on distinct encoding codecs tailored for their respective use cases.
The JBG (.JBG) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like SIXEL.
While specific technical details aren't available here, JBG files generally serve the purpose of storing image effectively within their domain.
Easily convert your SIXEL images to the JBG format using our fast and user-friendly online converter. Designed for seamless image format transformation, this tool supports high-quality conversions without the need to install software.
SIXEL is a bitmap graphics format primarily used for terminals and legacy systems, whereas JBG is a compressed bi-level image format designed for efficient storage and transmission. SIXEL images often have less compression and larger sizes compared to JBG files, which are optimized for size and quality balance.
Keep individual SIXEL source files under 50–200 MB for fastest conversion; very large terminal captures should be split into smaller chunks.
To preserve visual detail when converting to JBG, use adaptive dithering or higher-resolution targets before thresholding rather than aggressive downsampling.
For batch conversion, process multiple SIXEL files with consistent threshold and dithering settings to ensure uniform output across the set.
Note that JBG is a bi-level (black-and-white) format — color information in SIXEL will be lost unless you convert to halftone/dithered grayscale patterns.
