Why convert HTM to HTML?
HTM and HTML use the same underlying JPEG format, but some software and websites only accept one file extension. Renaming alone can sometimes cause issues - converting ensures the file is properly encoded with the correct extension.
This also lets you re-compress the image at a different quality level to reduce file size without needing any other tools.
