How to convert FLAC to MP3 on Windows

  1. 1

    Select your FLAC files

    In File Explorer or on the desktop, select one FLAC file or as many as you like. The first time, Filee offers to download FFmpeg, the free engine it uses for this conversion.

  2. 2

    Hold Ctrl and drag

    Hold Ctrl (or the key you set in Filee) and drag the files. A donut of formats opens at the cursor. Prefer menus? Right-click and choose Convert with Filee.

  3. 3

    Drop on MP3

    Release the files over MP3. A progress ring counts up, and each MP3 file is saved next to its original.

What Filee does for FLAC → MP3

Keep your lossless FLAC library at home and put MP3 copies on the phone, a USB stick for the car or an older player that doesn't play FLAC. Whole albums convert in one go.

  • Uses FFmpeg, a free optional engine that Filee downloads once into its own folder (about 100 MB). Programs installed on your PC are never used.
  • The MP3 128k preset makes smaller files, ideal for speech.
  • Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
  • Private: files are converted on your PC and never uploaded, even without internet.
  • Saved next to the original, or in a folder and with a file name pattern you choose.

FLAC can also become

  • M4A
  • WAV
  • OGG
  • OPUS
  • AAC

About FLAC and MP3

FLAC lossless audio

FLAC is lossless compressed audio: it shrinks files to roughly half the size of WAV without losing any quality, which makes it the favourite format for music libraries and hi-res downloads.

MP3

MP3 is the classic compressed audio format. Practically every player, car stereo and phone plays it, which makes it the safest choice for sharing music, podcasts and recordings.
