How PEF to ASF Conversion Works

PEF is a document format: it stores data in the PEF format. ASF is a video format that stores data in the ASF 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 ASF natively or when the target platform only accepts ASF. 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.
