Technical Details
Audio Codec Specifications
OPUS uses hybrid SILK and CELT codecs for efficient compression at 6-510 kbps, while FLAC employs linear predictive coding for lossless compression typically achieving 50-70% size reduction from uncompressed PCM audio.
Container Format Details
OPUS files use Ogg container format with Vorbis comments for metadata, while FLAC uses native FLAC container supporting extensive metadata fields including MUSICBRAINZ tags, embedded cue sheets, and application-specific data blocks.
Processing Requirements
Converting OPUS to FLAC requires decoding the lossy OPUS stream to PCM audio, then re-encoding with FLAC’s lossless algorithm. This process is CPU-intensive but doesn’t require specialized hardware acceleration.

Frequently Asked Questions
Will converting OPUS to FLAC improve audio quality?
No, converting from lossy OPUS to lossless FLAC won’t restore lost audio data. The quality will remain the same as the original OPUS file, but you’ll get better compatibility with audiophile equipment that supports FLAC.
How much larger will FLAC files be compared to OPUS?
FLAC files will be significantly larger, typically 3-10 times the size of OPUS files depending on the original OPUS bitrate. A 5MB OPUS file might become 25-50MB in FLAC format.
Does FLAC support the same sample rates as OPUS?
FLAC supports a wider range of sample rates up to 655,350 Hz and bit depths up to 32-bit, while OPUS is limited to 48kHz maximum. The conversion will maintain the original OPUS sample rate.
Will metadata and tags be preserved during conversion?
Yes, Convertify preserves metadata including artist, album, title, and other ID3 tags when converting from OPUS to FLAC. FLAC actually supports more extensive metadata than OPUS.
Can I convert OPUS files with embedded artwork to FLAC?
Yes, embedded album artwork and cover images will be transferred from OPUS files to the resulting FLAC files, maintaining your music library’s visual organization.
Is there any quality loss when converting OPUS to FLAC?
There’s no additional quality loss during the conversion process itself. However, since OPUS is already lossy, the FLAC file will contain the same quality level as the original OPUS source.
Why would I convert lossy OPUS to lossless FLAC?
Main reasons include compatibility with high-end audio equipment, archival purposes, professional audio workflows, and preparation for further audio processing where lossless input is preferred.
How long does it take to convert OPUS files to FLAC?
Conversion speed depends on file duration and system performance. Typically, a 4-minute OPUS song converts to FLAC in 10-30 seconds on modern Windows computers with multi-core processing.
