01
FLAC is a lossless format that prioritizes fidelity over size. Converting to OPUS introduces modern compression that typically reduces file size by an order of magnitude with no perceptible difference at normal playback or viewing.
02
OPUS is accepted by a wider range of audio players, car stereos, and streaming services than FLAC. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
OPUS files are typically smaller than their FLAC counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
