Audiophiles prefer the FLAC losless format over mp3 when it comes to listening to music. That's fine if you have enough storage space to store the larger FLAC files, but not so much if you do not have enough storage space to store files that take up five times as much space as mp3 files.

Many users like to keep FLAC files on their desktop computer and mp3 files of the same songs on their portable mp3 player or mobile phone. And if you want to burn music to CD, you will discover quite often that only mp3 and wav are supported as input formats, but not flac.

But how can you convert FLAC to mp3? Lets find out.

Convert Flac to Mp3

There are a lot of tools out there that promise free conversions but do not keep up to the promise. Some convert only 50% of the files while others nag you into buying the full version before they let you convert flac files to mp3.

Others still bombard you with adware offers, toolbars and such, during installation, and if you are not careful, you end up with unwanted software on your software and often also with changed search providers and a different browser homepage.

A free solution is Koyotesoft's Free Mp3 Wma Converter which supports the FLAC format among others. It does come with adware offers though, so pay attention to those during installation.

You need to pay attention to the program's setup though as it tries to install additional programs that you may not need. This includes a CD Ripper or a trial version of a shareware program. Additionally, it tries to install the Dealio toolbar and change the default search engine to Yahoo. All of those options can be disabled during installation.

Update: Offers may vary depending on data and time of your download.

You can drag and drop Flac files to the program interface or use the plus icon to add songs from the local hard drive.

Make sure mp3 is selected as the output format. You can change the default quality setting of 128 Kbps up to 320 Kbps there as well. A click on convert converts the FLAC files to mp3.

The program saves the converted files into the same directory by default. You can change that by unchecking "save in the file's directory" and selecting a different destination directory for the converted files. If you want, you can also have it remove the original files after the procedure.

Please note that you can select a different output format, supported are for instance ogg or wav as well (but not aac). The program uses Lame to encode the music into different formats. A click on the settings button opens the options window with many different settings.

You can add as many FLAC files as you want from the local hard drive, and all of them will be batch converted once you hit the convert button. File names will be retained, only the file extension changes to the selected format.

You can download the program from the developer homepage.

Other solutions you can try:

The Windows program that I have reviewed above is just one of the programs you can use for the conversion of flac to mp3 files.

The following list points to other services and programs that you can use for that purpose.

FlacSquisher

flaqsquisher

A free open source audio converter that can convert flac audio files to mp3 or ogg format files. Just point it to the Flac directory, select an output directory, select mp3 or ogg as the output format, and hit the encode button.

Comes without adware in the installer, and works really well.

Free Audio Converter

free audio converter

A free program that ships with adware in the installer. Pay attention to what is being offered to you in the installer, and make sure you select custom installation and uncheck any of the options made available to you.

The program itself is a universal audio converter that supports flac, mp3 and a variety of other audio formats. Just select add files, an output format and quality, and hit the convert button to start the conversion.

All3MP3

A software for Apple Macintosh systems. It can convert selected audio formats to Mp3. Supports a huge variety of audio formats, and should be your first choice if you are using a Macintosh computer.

Zamzar

convert-files

This online converted can come in handy if you need to convert Flac but cannot install software on your system. You can upload files that have a total size of up to 100 Megabytes.

The process itself is not as comfortable as running a software locally, as you may have to run the process multiple times due to the size limitation and also have to wait longer and hand over an email address of yours that is used for notifications, but if you cannot run software locally, it is better than not converting the files in first place.

    Hey what about Audacity?

    Free, never nag, open source goodness.

      Audacity is overkill if you just want to transcode audio. While it can convert between formats, its primary function is as an audio editor. It also takes awhile for the program to launch and audio files to load.

    Roger –

    The Format Factory site doesn’t mention converting FLAC files. Have you done this?

      KRS I just checked, the program supports FLAC.

      Yes, I’ve converted downloaded FLAC files to mp3 for my iPod, and Archos media players, when the files are not available as mp3.

        Even Gigabytes of space fill up fast if you use flac instead of mp3. Plus, not every mp3 player or mobile phone supports the flac format.

    I’ve been using Format Factory for ages. It offers many different audio, video and image conversions, as well as some more advanced functions, and is available, free, from http://www.formatoz.com/.

    I’ll stick with BonkEnc/fre:ac cause it’s full featured, open source, and doesn’t have a “pro/plus” version. It can even rip CDs.

    There are vague hints that the free version is time-limited or lacks functions. The site offers a “Plus” version for $24. What does the Plus version have that the free version does not. (The site doesn’t say.)

      I have no idea where the difference is, there is zero information on the homepage or the application. There have been no restrictions so far.
