How to convert FLAC audio to MP3 in Windows


While you will find many other paid tools to convert FLAC audio files to MP3, this guide will show you how to use just one free, open-source media converter (which can also perform other file conversions) to convert FLAC to MP3: MediaCoder.

MediaCoder is a free, open-source media converter for Windows XP and Windows Vista . It can convert most formats of video and audio. If you are looking for an open source, free FLAC converter, look no further than Media Coder. It is being improved constantly, and has the advantage of being open source. This means that it has support for most file formats. It can also help you convert audio for popular mobile devices (PSP, iPhone/iPod). It is fully standalone, which means that it does not depend on system codecs.

Note: I am using Windows XP in this tutorial. Desktop has been advised as the location to save files in steps below because it is the easiest. If you know your way around drives and partitions, use any other folder you wish to.

Convert FLAC to MP3

Below are the instructions to convert FLAC files to MP3 format.


If you are on Mac OS X, follow our tutorial “Convert FLAC to MP3 on Mac” instead.

Step 1: Download and install Media Coder

MediaCoder is free and open-source, which means that you do not have to spend a penny to get it. Download MediaCoder from here, and install it. After installing, start up Media Coder.

Step 2: Add File/folder

To simplify the process, place all FLAC files on your desktop. If you have more than one file, put it into a folder in the desktop.

After opening up MediaCoder, click the “Add” icon on top left corner to get a drop down menu. If you want to convert only one file, click Add file. If you want to convert a full folder of tracks, click Add folder. Click “Desktop” and add the file/folder.

Right-click on the file you added, and click “Set output folder”. A window will come up – click “Desktop”.

Step 3: Edit settings for conversion

convert .flac to .mp3
Click on the Audio tab on left side (as shown on screenshot below), and then click on the “LAME MP3” tab on the right side (also in screenshot below). Adjust Bit Rate to 5 and Algorithm Quality to 0.

.flac to .mp3
Now, hit F5 (or alternatively, click Transcode menu on top, and click “start transcoding”. Your file will now be converted – sit back, and maybe grab a coffee if you have several files to convert.

FLAC: More information

FLAC is an abbreviation of Free Lossless Audio Codec. Lossless implies that no quality is lost while converting to FLAC format. This also means that the level of compression when using FLAC will be less. In contrast, MP3, a popular audio format, is lossy, which means that you lose some original quality while converting to it.

Most humans cannot understand the difference between FLAC and MP3 of a sufficiently high bit rate. Hence, MP3 format is preferred for its space saving benefits. Another advantage of MP3 format is that it is supported by most digital devices – mobile phones, MP3 players, CD-walkmans, stereo setups and DVD players.


  1. Thanks a million for this! I searched for HOURS for a free Audio Converter so I could listen to my flac files on an MP3 player. This program needs more exposure, it really should have been the first one to come up in search engines.

    I had to of downloaded at least 6 different programs claiming to be free, only to tell you you need to purchase it once you download, install and run it.

    I am converting two albums as I type this :-)

  2. I’ve checked heaps of websites today and i am relieved to find one that is reliable, easy to use and free. Thanks

  3. I was introduced to FLAC files today and thanks to your post, I can play those files on my mp3 layer today as well.

    Thanks a lot.

  4. Thank you for pointing out this program. it is easy to operate and all my flacs was converted into mp3’s. Again thanks.

  5. Sumesh, Thanks a million! For the technologically challenged like myself this has been a great tip. I could hear my files no probs (I recommend BSPlayer, it can play all sorts of music and video files!) but now I’ll be able to transfer to my ipod. Perfect.
    thanks again and keep the good work.

  6. Glad you found Media Coder useful – i’ve been using it for along time. The only problem is its dull UI – if only I was a UI designer, I’d have worked on it…..

  7. Thank you for pointing me in the direction of MediaCoder. What an excellent and easy to use program. I really appreciate it.

  8. Thanks, finally found something OS to convert the occasional flac files to MP3 to save space on my laptop.
