ARW is a image format: it stores data in the ARW format. RMVB is a document format that stores data in the RMVB 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 RMVB natively or when the target platform only accepts RMVB. 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.
