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. WAV is a audio format that stores uncompressed PCM audio samples at full bit depth, giving lossless fidelity at the cost of large file sizes. This extracts the audio stream from the video container, discarding the video track. The audio track is decoded and re-encoded (or stream-copied if the codec matches) while the video frames are discarded. Converting between these two formats is common when the source application does not support WAV natively or when the target platform only accepts WAV. 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.
