Convert Microsoft Hyper-V virtual hard disk files (VHDX) into sector-by-sector disk images (IMG) quickly and securely with ConvertX. This conversion is essential for system administrators and developers migrating virtual machine storage to physical drives or alternative hypervisors.

The VHDX format is a modern virtual hard disk container developed by Microsoft, supporting large capacities up to 64TB and power failure resilience. In contrast, the IMG format is a raw, sector-level binary dump of storage data without proprietary virtualization metadata. When converting VHDX to IMG, ConvertX extracts the raw partition tables, file systems, and user data from the Hyper-V container and structures them into a universal block-level disk image that can be flashed directly onto physical media or mounted by various disk utilities.

This conversion is strictly lossless, meaning all sector data, file structures, and boot records are preserved completely intact without altering data fidelity.

  • + VM formats bundle entire systems
  • + Preserves exact byte-level copies
Disadvantages
  • − Images are often several gigabytes
  • − Conversion between VM formats can be slow
  • − Boot sectors may break if format changes
🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Frequently asked questions

No. The conversion is entirely lossless, preserving the exact bit-for-bit structure of the virtual disk.
The file size changes insignificantly, though it may expand if the VHDX was dynamically expanding and evaluated at its full allocated capacity.
Yes, once converted, the IMG format can be written sector-by-sector to physical storage using standard flashing tools.
