How ICO to RST Conversion Works

The Windows Icon format bundles multiple raster images at different resolutions (16x16 through 256x256) into a single file for use as application icons. Converting to RST produces a document file that stores data in the RST 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. This makes RST the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
