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.
Convert your Virtual Hard Disk (VHD) files into QCOW2 format seamlessly. This tool is essential for administrators migrating virtual machines from Microsoft Hyper-V to KVM or QEMU environments.
VHD is a proprietary format primarily used by Microsoft virtualization platforms, while QCOW2 (QEMU Copy-On-Write) is the native format for KVM-based hypervisors. Converting VHD to QCOW2 allows you to leverage features like internal snapshots, zlib compression, and AES encryption that are specific to the QEMU architecture.
The conversion process is a bit-perfect data migration; it preserves the disk structure and file system integrity without degrading the virtual storage contents.
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.
