Converting FLAC to AAC trades perfection for portability: your FLAC keeps every sample it was born with, while AAC is built for streaming-grade sound at friendly file sizes. At a sensible bitrate the difference is genuinely hard to hear, but it's a one-way door: hold on to the FLAC original if it's precious, because no AAC can hand those samples back.

FYI

One-way door: AAC is lossy, so this conversion throws data away to get small. Keep the FLAC original if you might ever need full quality again.

Why flip FLAC to AAC

FLAC is the audiophile's handshake: CD-perfect sound at roughly half the shelf space. It was born in 2001, Josh Coalson; now kept by the open Xiph.Org Foundation, and its real weak spot is fitting in pockets: lossless is still large: and charming Apple's own apps.

AAC is MP3's better-trained successor: cleaner sound from the same number of bits. Advanced Audio Coding: the default soundtrack of YouTube, iTunes and most MP4 video. That makes it the right destination when what you need is streaming-grade sound at friendly file sizes.

FLAC vs AAC, side by side

Type	audio · lossless	audio · lossy
Best for	archiving music with zero quality loss and a genuine size saving	streaming-grade sound at friendly file sizes
Weak spot	fitting in pockets: lossless is still large: and charming Apple's own apps	older or stubborn hardware that only ever learned MP3
Typical size	around 5 MB per minute: half of WAV, five times an MP3	similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller
Plays on	Hi-fi gear, Android, VLC, most desktop players; iTunes and Apple Music look away.	Apple everything, YouTube, Android, modern players; patchy on legacy gear.

Questions people ask

Will converting FLAC to AAC lose quality?

A little, by design: AAC is a lossy format. At 192 kbps or above most people can't tell the difference, but the discarded data can't be recovered later.

Will the AAC file be bigger or smaller than my FLAC?

Dramatically smaller. FLAC runs around 5 MB per minute: half of WAV, five times an MP3; AAC comes in at similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller.

Where will the AAC file play?

Apple everything, YouTube, Android, modern players; patchy on legacy gear. That's the usual reason people leave FLAC behind: AAC simply opens in more of the places that matter.

How long does FLAC to AAC conversion take?

Seconds for most files: audio is light work. A long recording might take a minute; your file auto-deletes from our servers within an hour either way.
