What is VHDX?

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

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.

When Should You Use VHDX vs IMG?

VHDX vs IMG: Key Differences

• •VHDX uses lossless compression while IMG uses lossless compression — both take the same approach to file size management.
• •Since both VHDX and IMG 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: IMG supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: Up to 64TB with improved performance for VHDX vs Exactly equals source disk size for IMG.
• •Use case fit: VHDX targets modern hyper-v virtual disks, large capacity vms and IMG targets floppy disk backups, forensic disk imaging — your choice depends on which workflow stage you are serving.

Advantages of VHDX

• ✓VHDX compresses data using lossless methods, keeping file sizes manageable for Modern Hyper-V virtual disks, large capacity VMs.
• ✓Industry-wide support means VHDX files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes VHDX the gold standard for archival and master copies.
• ✓From professional software to open-source alternatives, VHDX works out of the box.

Advantages of IMG

• ✓IMG applies lossless compression specifically calibrated for Floppy disk backups, forensic disk imaging.
• ✓IMG enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓IMG guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find IMG support built into virtually every tool that handles Floppy disk backups, forensic disk imaging — no plugins or converters needed.
