How WEBM to MP4 Conversion Works
WEBM is a video format: it packages VP8/VP9 or AV1 video with Vorbis/Opus audio in a royalty-free container designed for web streaming. MP4 is a video format that packages H.264 or H.265 video with AAC audio in a container format widely supported across every platform and device. This conversion changes the file's encoding, compression method, and supported feature set. When the source codecs already match the target container the streams are copied without re-encoding (zero quality loss); otherwise the video is re-encoded at a configurable quality. Converting between these two formats is common when the source application does not support MP4 natively or when the target platform only accepts MP4. 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.
