RA file (RA) stores data in the RA format. MPG file (MPG) stores data in the MPG format. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard MPG file readable by any compatible application. 1converter handles RA-to-MPG 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.
