Convert your raw disk images to Microsoft Virtual Hard Disk format instantly. This tool helps system administrators and developers prepare storage for Hyper-V environments.

The IMG format is a raw sector-by-sector dump of a storage medium, whereas VHD is a virtual hard disk container format natively supported by Microsoft virtualization products like Hyper-V and Virtual PC. During the conversion process, the raw partition and file system structure of the IMG file are wrapped into the VHD structure, allowing hypervisors to mount the disk image as a virtual drive.

Because both IMG and VHD are disk image formats storing raw sector data, the conversion happens without quality loss. Your file's data integrity is preserved 100% byte-for-byte.

Tips

Ensure your source IMG file is not corrupted before starting the conversion.
Check that your target Hyper-V environment supports fixed or dynamically expanding VHD structures depending on your storage needs.
Verify free disk space on your machine, as handling large disk images requires sufficient temporary overhead.

Common use cases

Migrating a physical or raw disk backup (IMG) into a Microsoft Hyper-V virtual machine.
Testing raw operating system installations inside a Virtual PC testing lab.
Accessing raw sector disk dumps on Windows workstations using native VHD mounting.
