# Convert Opus to FLAC

Convert Opus to FLAC right in your browser — free, private, nothing is uploaded. Get a lossless file any editor opens — no further quality loss.

Opus delivers the best quality per bit of any mainstream codec — it beats MP3, Vorbis and AAC at almost every bitrate and powers WhatsApp voice notes, Discord and WebRTC. Device support, though, is still patchy outside browsers and messengers.

FLAC compresses audio without losing anything — a perfect, bit-for-bit copy at a fraction of the WAV size, which makes it the default choice for archiving music.

Converting Opus to FLAC is about compatibility rather than quality: some editors, DAWs and pipelines simply insist on FLAC. You get a file they open natively — but the audio can never get better than the Opus you start from.
