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 VHD?

Virtual Hard Disk (VHD) is Microsoft's virtual disk format for Hyper-V and Windows Virtual PC, storing full disk images.

When Should You Use IMG vs VHD?

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 VHD When...

Reach for VHD when your priority is hyper-v virtual machines, windows virtual disks — its uncompromising quality ensures every detail is preserved.

IMG vs VHD: Key Differences

•IMG uses lossless compression while VHD uses lossless compression — both take the same approach to file size management.
•Since both IMG and VHD use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
•How transparency is handled: VHD supports transparency, so alpha information is preserved during conversion.
•IMG files are typically Exactly equals source disk size while VHD files range Up to 2TB, supports dynamic expansion
•IMG is optimized for floppy disk backups, forensic disk imaging while VHD is designed for hyper-v virtual machines, windows virtual disks — choose based on your specific workflow needs
