The DJVU format corresponds to .DjVu or .DJV files, which are usually scanned documents that you are interested in converting to PDF. After all, it is much more likely for someone you’ll be sharing the file with to have a PDF-compatible reader.
In case you have not yet scanned the document, remember that, a simple photograph with your mobile’s camera will let you convert JPG to PDF; thus, your scanned document will be ready to be sent. In this case, we are offering you a free tool to convert DJVU to PDF.
