The Waveform Audio File Format format stores uncompressed PCM audio samples at full bit depth, giving lossless fidelity at the cost of large file sizes. Converting to MOV produces a video file that packages video and audio in Apple's QuickTime container, which can hold ProRes, H.264, or HEVC tracks. 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. This makes MOV the practical choice when the destination system requires it or when the original format is not supported by the target application. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.
