How do I convert a FLAC file to OPUS?

Upload your FLAC file to the converter, choose OPUS as the output format, select your desired bitrate (e.g., 128 kbps for near-transparent quality), and click Convert. Once the file is processed, download the .opus file. Your original FLAC remains untouched, and the conversion happens in your browser for privacy.

Why should I convert FLAC to OPUS instead of keeping FLAC?

FLAC is lossless and ideal for archiving, but OPUS is a highly efficient lossy codec that reduces file size by up to 80% while preserving perceptible audio quality at bitrates like 128 kbps. OPUS is also natively supported in web browsers and many portable devices, making it a practical choice for streaming, sharing, and saving storage space.

What happens to the audio quality when converting FLAC to OPUS?

FLAC stores a perfect digital copy of the original audio, while OPUS uses a psychoacoustic model to remove inaudible content. The sample rate, channel count, and duration are preserved, but the bitrate you choose determines the trade-off between size and transparency. For example, at 160 kbps, OPUS is generally regarded as transparent for most listeners, meaning the output is indistinguishable from the original lossless source.
