Convert JPG to DJV

Understanding JPG and DJV file formats

JPG (or JPEG) is a widely used raster image format known for its efficient compression and compatibility across devices and platforms. It is commonly used for photographs and web images due to its balance between image quality and file size.

DJV refers to the DjVu file format, which is designed for storing scanned documents, especially those containing a combination of text, line drawings, and photographs. DjVu files offer high compression ratios, making them ideal for distributing large documents online.
