Convert AVHD to another file type
To convert AVHD snapshots to another format, you need Microsoft Hyper-V or other Disk Image software.
Convert a file to AVHD
To convert other file formats to the "Hyper-V Differencing Disk" file type, you need software like Microsoft Hyper-V or a similar tool.
About AVHD files
The .AVHD file is a Microsoft Hyper-V differencing virtual disk used to store virtual machine state data when a snapshot (or checkpoint) is created. These files act as delta layers, recording only the block-level changes made to the guest operating system after the snapshot was initiated. To open and manage these files, system administrators rely on Microsoft Hyper-V or native Windows PowerShell cmdlets. The primary disadvantage of the .AVHD format is its strict dependency on a parent VHD base disk. An orphaned .AVHD file is completely useless on its own because it only contains fragmented binary changes rather than a complete, readable file system. Furthermore, these differencing disks grow dynamically, often exceeding hundreds of gigabytes and consuming massive amounts of physical storage if snapshots are left unmerged for too long. Standard online document converters fail to process these files because of their extreme size, proprietary nature, and interdependent disk architecture. For users looking to standardize or backup their virtual machines, the best approach is to merge the .AVHD data back into the parent VHD or export it to the newer, more resilient VHDX format using the Hyper-V Manager interface. Because this is a complex, proprietary virtual machine component, traditional web conversion is severely limited.
Convert.Guru analyzes your AVHD file, detects the exact format, and lets you read the text inside.
If you want to convert AVHD file to VHD, ISO, IMG, DMG, VMDK, VDI, HDD, QCOW, QCOW2, RAW, VBOX or OVA, you can use Microsoft Hyper-V or similar software from the "Virtual Machine Snapshot Storage" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to AVHD, try Microsoft Hyper-V or another comparable tool in the "Virtual Machine Snapshot Storage" category.
The AVHD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our AVHD converter.
