WAV is a audio format: it stores uncompressed PCM audio samples at full bit depth, giving lossless fidelity at the cost of large file sizes. OGG is a audio format that encodes audio with the open-source Vorbis lossy codec in the Ogg container, achieving quality comparable to AAC at equivalent bitrates. 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 OGG natively or when the target platform only accepts OGG. 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.
