Convert FLAC to AAC

Upload a FLAC file and convert it to AAC — all in your browser.

Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.

What happens when you convert FLAC to AAC

Your lossless FLAC is decoded and re-encoded with AAC, the codec used by YouTube, Apple Music, and most streaming services. At the same bitrate, AAC generally sounds better than MP3, so you get smaller files with less compromise.

The output is a raw .aac stream in ADTS form. That is exactly what some streaming and broadcast tools want, but it is a bare stream: .aac files have no standard place for album art or tags.

AAC or M4A?

If you want AAC audio for everyday listening, M4A is usually the better wrapper. It holds the same AAC audio inside an MP4 container that supports titles, artists, and cover art, and it is what iTunes and Apple devices expect. Use the FLAC to M4A converter for that.

Choose raw .aac when a tool or pipeline specifically asks for an ADTS stream, for example some HLS and broadcast workflows.
