AVI is a video format: it interleaves audio and video streams in a Microsoft container format that supports many codecs but lacks modern streaming features. DDS is a document format that stores data in the DDS format. This conversion changes the file's encoding, compression method, and supported feature set. 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 DDS natively or when the target platform only accepts DDS. 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.
