Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Easily convert your Hyper-V VHDX virtual disk images into the QCOW2 format used by KVM and QEMU. This tool is essential for developers and sysadmins migrating virtual machines from Windows environments to Linux-based hypervisors.
VHDX is the native format for Microsoft Hyper-V, designed for high-performance storage and resilience, while QCOW2 (QEMU Copy-On-Write) is the standard format for open-source virtualization platforms. Converting VHDX to QCOW2 involves remapping the virtual disk structure and metadata to ensure compatibility with the QEMU block driver, allowing your VM to run natively on KVM-based systems.
The conversion process is bit-accurate; the internal data of the disk remains unchanged, ensuring no loss of file integrity or OS state.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
