VMDK file (VMDK) stores data in the VMDK format. 7-Zip Archive (7Z) uses the LZMA2 algorithm to achieve compression ratios 30-70% better than ZIP, with optional AES-256 encryption. This packages the document into a compressed archive for smaller transfer size. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard 7Z file readable by any compatible application. 1converter handles VMDK-to-7Z conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
