POTM to JBG conversion is the process of transforming a Microsoft PowerPoint macro-enabled template file (POTM) into a JBG (Joint Bi-level Graphics) image format. This conversion extracts slide visuals or exported images from the POTM presentation and encodes them as JBG bitonal/compressed images suitable for high-compression, black-and-white graphics use.

Drag your .POTM file from your computer or use the browse function.
Confirm .jbg as the selected destination format.
Click "Convert" and download your converted .JBG file once ready.
POTM files use the MIME type application/vnd.ms-powerpoint.template.macroenabled. They contain presentation templates with macros and multimedia elements. JBG files use the MIME type image/jbig, typically employed for lossless bi-level image compression in scanning and faxing applications. The JBG format relies on JBIG codec technology for efficient compression.
The JBG (.JBG) format is commonly used for presentation. Understanding its characteristics can be helpful when converting to or from other formats like POTM.
While specific technical details aren't available here, JBG files generally serve the purpose of storing presentation effectively within their domain.

POTM files are Microsoft PowerPoint template files primarily designed for presentation creation and editing, supporting animations and slide layouts. By contrast, JBG is a raster image format used for high-quality bi-level image compression, ideal for archiving images but not for editable presentations. Converting POTM to JBG extracts static visual content in a highly compressed image format.
Keep individual slide exports under 5 MB for best processing speed; large embedded media can be flattened or removed before conversion to reduce size.
To preserve legibility when converting to bi-level JBG, increase contrast and use dithering rather than aggressive compression; convert text to vector outlines or high-contrast raster before export.
For bulk conversions, group slides by target quality settings and run conversions in batches to maintain consistency and use automated scripts or queue tools to avoid manual repetition.
Limitations: JBG is a bi-level (black-and-white) format so continuous-tone colors and gradients will lose color information; complex animations and macros in POTM are not preserved—only static slide visuals are exported.
