APE is a audio format: it stores data in the APE format. WEBM is a video format that packages VP8/VP9 or AV1 video with Vorbis/Opus audio in a royalty-free container designed for web streaming. This wraps the audio track in a video container, which some platforms require for upload. 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 WEBM natively or when the target platform only accepts WEBM. 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.
