What is PKG?

PKG files are built around lossy compression. Designed for macos software installation, package extraction, application repackaging, they use the application/x-pkg MIME type and typically range from varies by content.

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 PKG vs VHD?

Use PKG When...

Reach for PKG when your priority is macos software installation, package extraction, application repackaging — its efficient compression makes sharing fast and storage minimal.

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.

PKG vs VHD: Key Differences

•PKG and VHD diverge on compression: lossy compression for the source, lossless compression for the target.
•Converting from PKG to VHD changes compression type: lossless source becomes larger but with full quality preservation.
•Transparency: N/A
•VHD files tend to be differently sized than PKG
•Primary audience: PKG is built for macos software installation, package extraction, application repackaging scenarios, while VHD focuses on hyper-v virtual machines, windows virtual disks — pick the format that matches your output requirement.

Troubleshooting PKG to VHD Conversion

!The converted VHD archive is smaller than expected → some files may have been skipped; verify the file count matches the source
!File permissions lost in the converted VHD → not all archive formats preserve Unix permissions and ownership metadata
!The VHD archive extracts to a different folder structure → verify that the source archive stored paths relatively, not absolutely
!Encrypted PKG files converted to VHD lost their encryption → encryption must be re-applied after format conversion
