LZO file (LZO) stores data in the LZO format. RAR Archive (RAR) compresses files with the proprietary RAR algorithm, typically achieving better ratios than ZIP for mixed-content archives. 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 RAR file readable by any compatible application. 1converter handles LZO-to-RAR 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.
