Microsoft Visio supports export to JPEG format, so getting a TIFF file from the JPEG should not be a problem with any graphics editor that supports TIFF format (check out the jpg to tiff conversion entry).
Alternatively, you can try to use some other program with Visio format support, but it's usually better to use the native program as 3rd party program may have problem with latest proprietary and closed formats, such as VSDX format.
