JPEG Image (JPG) uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. PPM file (PPM) stores data in the PPM 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 PPM file readable by any compatible application. 1converter handles JPG-to-PPM 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.
