AFF to JBG conversion is the process of transforming a drawing or vector-based AFF (AmiPro/Amiga Frame Format) file into a JBG (Joint Bi-level Group) file, a compressed bi-level bitmap format used for black-and-white images. This conversion rasterizes AFF content into a bilevel (1-bit) image and applies JBG compression, producing smaller monochrome files suitable for faxing, archival, or legacy imaging workflows.

AFF files usually have the MIME type image/vnd.aff and are used for storing high-quality image data, often in professional imaging workflows. JBG files use the MIME type image/jbg and employ JBIG compression, which efficiently compresses bi-level images such as scanned documents. Both formats support lossless and lossy compression codecs depending on usage scenarios.
The JBG (.JBG) format is commonly used for drawing. Understanding its characteristics can be helpful when converting to or from other formats like AFF.
While specific technical details aren't available here, JBG files generally serve the purpose of storing drawing effectively within their domain.
Easily convert your AFF files to the JBG format using our efficient and user-friendly online AFF to JBG converter. Designed to provide quick results without compromising quality, this tool supports hassle-free conversion directly from your browser.
AFF files typically serve as a flexible container format ideal for raw image data, while JBG is a compressed bi-level image format optimized for black-and-white images. Unlike AFF, JBG focuses on reducing file size with lossy compression, making it more suitable for quick display and transmission. Choosing JBG over AFF can improve compatibility with legacy imaging systems.
Keep source AFF pages under 10–20 MB each for faster conversion; very large vector pages can be rasterized into huge bitmaps—simplify complex vectors first.
To preserve detail, use a higher output resolution (300–600 DPI) and set JBG compression to medium or low; for pure line art, lower DPI with lossless-like settings can be sufficient.
For batch conversion, convert pages to individual JBG files or a single multi-page JBG using a script/tool that preserves naming and page order.
Be aware JBG is a bilevel (black-and-white) format: color and grayscale from AFF will be thresholded or dithered—check dithering/threshold settings to avoid losing important tonal detail.

Some AFF features (advanced vector effects, transparencies, and layers) may not translate perfectly to JBG since JBG is a raster bilevel format; flatten or rasterize complex elements before conversion.
