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 AC3?
AC3 is an audio format. Converting it trades off file size, quality and compatibility to fit where the sound will be played.
Why convert FLAC to AC3?
Most people convert FLAC to AC3 for compatibility — a website, app or device insists on AC3, and FLAC simply won't open. AC3 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.
When you'd convert FLAC to AC3
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.
