AV1 Image File Format (AVIF) applies AV1 intra-frame compression delivering 50% smaller files than JPEG at equivalent quality, with wide colour gamut support. PGM file (PGM) stores data in the PGM 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 PGM file readable by any compatible application. 1converter handles AVIF-to-PGM 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.
