Conversor en línea AAC→FLAC gratuito. Rápido, privado, sin registro.
Need to turn a AAC file into a FLAC file? This converter does it in seconds and downloads the result automatically. Drop in your AAC file (a .aac) and download a ready-to-use FLAC file (a .flac) — no software to install, no account to create, and no watermark on the output.
AAC is the successor to MP3: better quality at the same bitrate, and the default for Apple, YouTube and most streaming.
FLAC is lossless but compressed, giving bit-perfect audio at roughly half the size of WAV — the audiophile and archival choice.
Most people convert AAC to FLAC for compatibility — a website, app or device insists on FLAC, and AAC simply won't open. FLAC 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.
Going from the lossy AAC to the lossless FLAC won't recover detail AAC already discarded, but it gives you a clean, re-editable copy that won't degrade further when you edit and re-save it.
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.
Privacy is the default here. Your AAC 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.
