Simply put, it is impossible to convert VMDK to VMX directly.
Thus, there is no so-called vmdk to vmx converter or a free online .vmdk to .vmx conversion tool.

Understanding vmdk and vmx file formats
VMDK (Virtual Machine Disk) is a disk image file format developed by VMware. It stores the contents of a virtual machine's hard disk, including the operating system, applications, and data. VMX (Virtual Machine Configuration) is a configuration file used by VMware products to define the settings and hardware configuration of a virtual machine, such as memory, CPU, network, and the location of the associated VMDK files.
Purpose of converting vmdk to vmx
Converting a VMDK file to a VMX file is not a direct file format conversion. Instead, it involves creating a new VMX configuration file that references an existing VMDK disk image. This is useful when you have a VMDK file but lack the corresponding VMX file needed to run the virtual machine in VMware products.
How to create a vmx file from a vmdk
To generate a VMX file for your VMDK disk, follow these steps:
- Open VMware Workstation or VMware Player.
- Go to File → New Virtual Machine.
- Select I will install the operating system later and click Next.
- Choose the appropriate guest operating system and version, then click Next.
- Set the virtual machine name and location, then click Next.
- When prompted for a disk, select Use an existing virtual disk and browse to your VMDK file.
- Finish the wizard. VMware will create a new VMX file in the specified location, referencing your VMDK.
Recommended software for vmdk to vmx conversion
The best software for this process is VMware Workstation (Windows/Linux) or VMware Fusion (macOS). Both allow you to create a new VMX configuration file for an existing VMDK disk easily. VMware Player is a free alternative for non-commercial use.
Tips and considerations
- Ensure the VMDK file is not corrupted and is compatible with your VMware version.
- If you have multiple VMDK files (split disks), select the first file (usually ending in -flat.vmdk or -s001.vmdk).
- After creating the VMX file, you may need to adjust hardware settings in VMware to match your original VM.
