What is IMG?

Raw Disk Image (IMG) is a sector-by-sector byte copy of a disk or floppy drive, used for cloning and forensic imaging.

What is VHDX?

Virtual Hard Disk v2 (VHDX) is the enhanced Hyper-V format supporting larger capacity, 4K sector alignment, and data corruption protection.

When Should You Use IMG vs VHDX?

Use IMG When...

Reach for IMG when your priority is floppy disk backups, forensic disk imaging — its uncompromising quality ensures every detail is preserved.

Use VHDX When...

Reach for VHDX when your priority is modern hyper-v virtual disks, large capacity vms — its uncompromising quality ensures every detail is preserved.

IMG vs VHDX: Key Differences

•IMG and VHDX diverge on compression: lossless compression for the source, lossless compression for the target.
•Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
•Transparency: N/A
•File sizes: IMG files typically range Exactly equals source disk size and VHDX files Up to 64TB with improved performance.
•Use case fit: IMG targets floppy disk backups, forensic disk imaging and VHDX targets modern hyper-v virtual disks, large capacity vms — your choice depends on which workflow stage you are serving.
