The jbg file extension is associated with Jarnal, a Java-based, multiplatform application for taking notes, sketching and editing PDF documents.
A jbg file contains a background image for use in Jarnal. It is intended to be used by Jarnal as part of the application's document and page workflow rather than as a general-purpose image file.
The format is specific to Jarnal and is best handled with the application and its Java runtime environment.
Open the jbg file with Jarnal. Because Jarnal is Java-based and multiplatform, it can be used on supported systems with a compatible Java runtime.
The file may be used by Jarnal as a background image rather than opened as an independent image.
Open the jbg file in Jarnal and use the application's document export options if the background is needed as part of an exported note or PDF.
