We have found one software suitable in our database for this conversion.
A vmdk to iso conversion essentially represents the transformation of virtual hard drive (.vmdk file) to standard .iso file used to store CD/DVD images. The most convenient way to achieve this would be to use VMware and its tools, by mounting the .vmdk file and using the data to create .iso image.
Alternative approach would require some utility designed to convert vmdk to iso, unfortunately we do not know about any for Windows, but on Linux you can use the command like to convert vmdk to iso.
VMDK
A vmdk file extension is used for default virtual disk format of VMware virtualization software. A vmdk file stores contents of virtual machine hard disk drive. There can be more vmdk files for each virtual machines, depending on the specified amount of virtual hard drive assigned to it. It also can store information about partitions virtual drive is able to access.
ISO
Files with iso extension are generally used for common CD/DVD disk image format. ISOs are used as a standard backup format of physical disks and are widely supported by burning or virtualization software.
