Windows Icon (ICO) bundles multiple raster images at different resolutions (16x16 through 256x256) into a single file for use as application icons. MXF file (MXF) stores data in the MXF 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 MXF file readable by any compatible application. 1converter handles ICO-to-MXF 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.
