About converting FLAC to Opus
Need to turn a FLAC file into a Opus file? This converter does it in seconds and downloads the result automatically. Drop in your FLAC file (a .flac) and download a ready-to-use Opus file (a .opus) — no software to install, no account to create, and no watermark on the output.
What is FLAC?
FLAC is lossless but compressed, giving bit-perfect audio at roughly half the size of WAV — the audiophile and archival choice.
What is Opus?
Opus is a modern open codec that beats MP3 and AAC at low bitrates, which is why it powers most voice chat and is excellent for speech and music alike.
Why convert FLAC to Opus?
Most people convert FLAC to Opus for compatibility — a website, app or device insists on Opus, and FLAC simply won't open. Opus is widely supported, which makes it a dependable target. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
FLAC vs Opus: what changes
Opus is lossy, so expect a much smaller file than FLAC — usually at a cost in fidelity small enough to be invisible at normal viewing sizes.
When you'd convert FLAC to Opus
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Is it private?
Privacy is the default here. Your FLAC file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
