HOW IT WORKS

How to use FLAC to AAC for free

  1. Choose a small FLAC audio file within the upload limit.
  2. Choose supported bitrate, sample rate and channels. Set start and end times if you need a clip.
  3. Convert, play the output and download it after checking sound and duration.

Check your result

Converting lossy audio to WAV or FLAC does not restore missing detail. File size depends on duration and settings; a WAV output can be much larger.

Example: Prepare a short audio clip as AAC for a compatible player, then compare playback with the original.

Online uploads and individual outputs are limited to 4 MB. Direct conversions need no account or payment. See all limits · Conversion tutorials.
