The APE file format stores data in the APE format. Converting to FLAC produces a audio file that applies lossless compression to PCM audio, preserving the original waveform exactly while reducing file size by 40-60% versus WAV. 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 FLAC 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.
