GIF is a image format: it stores up to 256 indexed colours per frame and supports frame-based animation in a single file. SGI is a document format that stores data in the SGI 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. Converting between these two formats is common when the source application does not support SGI natively or when the target platform only accepts SGI. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
