FLAC Converter for Mac: Free Ways to Convert FLAC

Card No. 06·14475 · Updated · Standard formula, shown below

If you need a FLAC converter for Mac, the easiest free options are the built-in Music app (formerly iTunes) for converting FLAC to Apple Lossless or MP3, and the open-source X Lossless Decoder (XLD) for converting FLAC to virtually any format. Both run natively on macOS and require no paid software. Below, we cover how to use them, what to watch out for, and when you might need a third-party tool.

Why Convert FLAC on a Mac?

FLAC (Free Lossless Audio Codec) is a popular format for music because it compresses audio without losing any quality. However, macOS and many Apple apps don’t natively support FLAC playback. For example, the Music app can’t play FLAC files, and older iOS devices won’t sync them. Converting FLAC to a compatible format like ALAC (Apple Lossless), MP3, or AAC lets you listen on your Mac, iPhone, or iPad without quality loss (if you choose a lossless format) or with smaller file sizes (if you choose a lossy format).

How to Convert FLAC in the Music App (Free)

The Music app on macOS can convert FLAC files to ALAC, MP3, AAC, and other formats, but you first need to add the FLAC files to your library. Here’s how:

  1. Open the Music app on your Mac.
  2. Go to Music > Settings (or Preferences) and click the Files tab. Click Import Settings.
  3. Choose the format you want to convert to. For lossless, pick Apple Lossless Encoder. For smaller files, pick MP3 Encoder or AAC Encoder. Set the quality (e.g., 256 kbps for MP3).
  4. Click OK.
  5. Drag and drop your FLAC files into the Music window. They will be added to your library (and may be copied to the Music folder).
  6. Select the imported FLAC files, then go to File > Convert > Create [Format] Version.
  7. The converted files appear in your library. Right-click them and choose Show in Finder to locate them.

Note: The Music app may not play FLAC, but it will still convert it. Also, the original FLAC files remain in your library unless you delete them.

Using X Lossless Decoder (XLD) for More Formats

X Lossless Decoder (XLD) is a free, open-source tool designed specifically for audio conversion on macOS. It supports FLAC, WAV, AIFF, ALAC, MP3, AAC, and many more. It also handles cue sheets and accurate CD ripping. To convert FLAC with XLD:

  1. Download and install XLD from the official website (xld.software).
  2. Open XLD. Go to XLD > Preferences and choose your output format (e.g., ALAC, MP3, FLAC). Set the quality settings.
  3. Drag and drop your FLAC files onto the XLD window (or click File > Open).
  4. Click Convert (the play button icon). The files will be saved to the same folder or a folder you specify.

XLD is more flexible than the Music app because it lets you convert to FLAC as well, and it preserves metadata and cover art better.

Choosing the Right Output Format

Your choice of output format depends on your needs:

  • Apple Lossless (ALAC) – Lossless, so no quality loss. Files are about half the size of WAV. Best if you want to keep the original quality and use Apple devices.
  • MP3 – Lossy, but universally compatible. A 320 kbps MP3 is nearly indistinguishable from the original for most listeners. Files are about 10% of FLAC size.
  • AAC – Lossy, similar to MP3 but slightly better quality at the same bitrate. Native on Apple devices.
  • WAV / AIFF – Uncompressed, huge files, but perfect for editing or archival.

If you only need to play on your Mac, consider just using a player like VLC or IINA that supports FLAC directly – no conversion needed.

Common Problems and How to Fix Them

Here are frequent issues when converting FLAC on a Mac:

  • Music app doesn’t show the Convert option – Make sure you’ve selected the FLAC files in your library, and that you’ve set an import format other than FLAC. The option is under File > Convert.
  • Converted files are silent or corrupt – This can happen if the FLAC file is corrupted or has unusual encoding. Try using XLD instead, or re-download the file.
  • Metadata (artist, album, cover) is lost – XLD preserves metadata better. In Music app, the converted file may not copy all tags. You can manually edit tags in the Music app or use a dedicated tag editor.
  • Files are too large after conversion – If you chose ALAC, files are still large. Choose MP3 or AAC for smaller sizes.
  • FLAC files won’t import into Music – If you have an older macOS version, you may need to update or use XLD.

Free vs. Paid Converters: What’s the Difference?

Free tools like XLD and the Music app cover most needs. Paid apps (e.g., Switch, All2MP3) offer batch conversion, more formats, and a simpler interface, but they aren’t necessary for most users. The main advantage of paid tools is convenience – they often provide drag-and-drop conversion with presets for specific devices. However, XLD is just as capable for FLAC conversion and is completely free. If you need to convert dozens of files regularly, XLD’s batch processing works fine – just drag all files at once.

Safety and Legality

Converting FLAC files you own is legal. However, downloading FLAC files from unauthorized sources may infringe copyright. Always ensure you have the right to convert and use the audio. Also, be cautious when downloading converter apps – stick to official sources like the Mac App Store or the developer’s website. Avoid tools that bundle adware or ask for unnecessary permissions.

Frequently Asked Questions

Can I convert FLAC to MP3 on a Mac without installing anything?

Yes. The Music app can convert FLAC to MP3, but you need to add the FLAC files to your library first. There’s no built-in standalone converter, but the Music app’s import settings let you choose MP3 as the output format.

Is there a way to convert FLAC to ALAC without losing quality?

Yes, both the Music app and XLD can convert FLAC to ALAC losslessly. The resulting file will be slightly larger than the FLAC, but the audio data is identical.

Why doesn’t my Mac play FLAC files?

macOS doesn’t natively support FLAC in QuickTime or the Music app. You can use VLC, IINA, or convert to a supported format like ALAC or MP3.

Can I convert FLAC to WAV on a Mac?

Yes, XLD can convert FLAC to WAV easily. The Music app can also convert to WAV if you select the WAV encoder in import settings.

Will converting FLAC to MP3 degrade the sound quality?

Yes, MP3 is a lossy format, so some audio data is discarded. At 320 kbps, the difference is hard to hear for most people, but audiophiles may notice. If you want to preserve quality, use ALAC or WAV.

How long does it take to convert a FLAC file?

It depends on your Mac’s speed and the file size. Typically, a 3-minute song converts in a few seconds. Batch converting an entire album may take a minute or two.
