OGG is a audio format: it encodes audio with the open-source Vorbis lossy codec in the Ogg container, achieving quality comparable to AAC at equivalent bitrates. NSV is a document format that stores data in the NSV 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 NSV natively or when the target platform only accepts NSV. 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.
