Source format: qcow2
qcow2 is the second version of the QEMU Copy On Write disk image format. It is widely used with QEMU, KVM, and other virtualization tools on Linux and Unix-like systems. qcow2 supports features such as snapshots, compression, encryption, and thin provisioning, which makes it a popular choice for virtual machine disks, testing environments, and cloud images.
Target format: vhd
VHD is a virtual hard disk format originally associated with Microsoft virtualization platforms and supported by many hypervisors and disk tools. It is commonly used with Hyper-V, older Virtual PC environments, and some backup or migration workflows. The main advantage of VHD is its broad compatibility with Microsoft-based virtualization systems and other tools that can read legacy virtual disk images.
How to perform the conversion
The most reliable way to convert qcow2 to VHD is with qemu-img, a command-line tool included with QEMU and available on Linux, macOS, and Windows.
- Install QEMU tools if they are not already available on your system.
- Make sure the source qcow2 image is not in use by a running virtual machine.
- Run the conversion command:
qemu-img convert -f qcow2 -O vpc source.qcow2 target.vhd - Wait for the process to finish, then verify the output file size and integrity.
In this command, -f qcow2 tells qemu-img the input format, and -O vpc selects the VHD output format, which QEMU labels as vpc.
If you prefer a graphical workflow, some virtualization suites and disk utilities can import qcow2 images and export them as VHD, but qemu-img is usually the fastest and most dependable option. You can also convert the file on 101convert.com for free, without installing any software.
Notes on quality, compatibility, or limitations
The conversion is usually lossless at the disk-image level, but the resulting VHD may not preserve qcow2-specific features such as snapshots, backing files, or encryption. If the qcow2 image is sparse, the converted VHD may become larger depending on the chosen VHD variant and the target platform.
For best compatibility with Hyper-V, confirm whether your environment expects fixed or dynamic VHD files. Also note that some older tools support only the original VHD format, while newer Microsoft workflows may prefer VHDX instead. After conversion, test the disk in the destination hypervisor before putting it into production.
