About converting FLAC to AAC
If something is asking you for a AAC file and all you have is a FLAC, this page is the fix. Drop in your FLAC file (a .flac) and download a ready-to-use AAC file (a .aac) — 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 AAC?
AAC is the successor to MP3: better quality at the same bitrate, and the default for Apple, YouTube and most streaming.
Why convert FLAC to AAC?
You'll reach for a FLAC to AAC conversion whenever the other end expects AAC specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. 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 AAC: what changes
AAC 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 AAC
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.
