CR2 file (CR2) stores data in the CR2 format. PEF file (PEF) stores data in the PEF format. This embeds the raster image inside a document container, fixing its dimensions on the page. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard PEF file readable by any compatible application. 1converter handles CR2-to-PEF 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.
