FLAC to MP3 Converter
Drop in FLAC files and get MP3 back in seconds, processed entirely on your device.
FLAC files (most other audio and video files work too). Files stay on your device.
How it works
- Choose your FLAC file, or drop it on the page. You can add several files at once.
- Choose MP3 quality: a bitrate (128 to 320 kbps; 192 kbps is a common balance) or leave the default.
- Click Convert. Processing happens on your device and shows progress; you can cancel at any time.
- Preview the result and download the MP3 file. With several files, download them all as one ZIP.
About FLAC to MP3 conversion
FLAC (Free Lossless Audio Codec) suits archiving a CD collection and keeping masters at about half the size of WAV. MP3 (MPEG-1/2 Audio Layer III) suits music libraries, podcasts and sharing when you cannot know what the listener uses.
Going from lossless FLAC to lossy MP3 trades a small, usually inaudible amount of detail for a much smaller file. Keep the FLAC original if you may want to edit or re-encode later.
For a 4-minute track, a typical FLAC file is about 24 MB and a typical MP3 file is about 6 MB. Your own result depends on the bitrate and the audio itself.
FLAC vs MP3
MP3 support: Plays on virtually every phone, car stereo, TV, browser and media player made in the last 25 years.
FLAC support: Plays in all current browsers, Android, and most music apps. Apple added full system support in iOS 11 and macOS High Sierra.

Quality and compatibility notes
- MP3: Each re-encode loses a little more detail, and there is no true gapless support without extra tags.
- FLAC: Still several times larger than MP3 or AAC, and not every car stereo or older player supports it.
- MP3 bitrate range: 128 to 320 kbps; 192 kbps is a common balance.
- Tags: MP3 stores ID3v1 and ID3v2 tags, including cover art.
Questions
Does converting FLAC to MP3 reduce quality?
A small amount of detail is discarded, which is how MP3 gets smaller. At a reasonable bitrate the difference is hard to hear.
How big will the MP3 file be?
For a 4-minute track, a typical FLAC file is about 24 MB and a typical MP3 file is about 6 MB. Your own result depends on the bitrate and the audio itself.
Is my FLAC file uploaded anywhere?
No. The conversion runs in your browser on your device. The file is never sent to a server, and nothing is stored after you close the page.
