The Free Lossless Audio Codec format applies lossless compression to PCM audio, preserving the original waveform exactly while reducing file size by 40-60% versus WAV. Converting to APE produces a audio file that stores data in the APE format. 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. This makes APE the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 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.
