How to Convert WAV to MP3 for Free on Your Computer (Windows & Mac)

There is good news for Mac users: you can convert WAV files to MP3 format without installing any additional software. The preinstalled Music app (formerly iTunes) is up to the task, although some simple setup is required first. Also, with the Music app, you can also process multiple WAV files at once.

You can follow the instructions below to safely convert your WAV files to MP3 in the Music app.

Step 1: Open the Music app.

Click the Music menu at the top and select Preferences.

Step 2: Click the Files tab, and then click on Import Settings.

Step 3: Select MP3 Encoder from the Import Using drop-down.

If you want to save the MP3 file in a specific quality, you can click the Setting and choose a preferred quality or set a custom one.

Click OK to confirm the settings.

Step 4: Drag your WAV file into the Music app and select it.

Step 5: Go to File > Convert > Create MP3 Version.

The conversion will start right away, and the converted MP3 file will be placed right under the original WAV file.

There are plenty of ways for converting WAV to MP3, and you can also try the following free tools. While they are not standard audio converters, they can still help you perform the conversion and achieve more purposes.

Audacity is a free, open-source, and cross-platform audio editing and recording app. It’s a good choice if you want to edit audio before converting. Here is how:

Step 1: Download Audacity from https://www.audacityteam.org/ and install it on your computer.

Step 2: Open it. Go to File > Open, then import your WAV audio.

Step 3: Edit, mix, and enhance your audio as needed. Then click File > Export Audio.

Step 4: Click Browse to select an output path. Then select MP3 Files from the Format dropdown box.
Optionally, you can modify the audio options, like channels, sample rate, bitrate mode and quality. For a regular WAV to MP3 conversion, you can use the following options:
• Channels: Stereo • Sample rate: 44100 Hz • Bit Rate Mode: Constant • Quality: 192 kbps (use 320 kbps if you want the best quality)

Step 5: Click Export to start the conversion process.
💡 If you want to convert multiple .wav into .mp3 at once, you’ll need to drag all the WAV files into Audacity. Then repeat Step 3 and Step 4 and select Multiple Files as the Export Range.

If you prefer a CLI-based solution, FFmpeg is what you’re looking for. But since it performs conversions via the command line, it’s best suited for advanced users.

Step 1: Download FFmpeg from https://ffmpeg.org/ and add it to your system’s PATH.

Step 2: Navigate to the folder containing your WAV files. Replace the file path with CMD, press Enter to bring up the Command Prompt in the selected directory.

Step 3: Run the following commands:
ffmpeg -i input.wav output.mp3
🔔 Replace “input” with your WAV filename and create a different name for the MP3 output.
Then press Enter to start the conversion.

💡 If you want to batch convert WAV to MP3 in FFmpeg, use this commands:
for %i in (*.wav) do ffmpeg -i "%i" "%~ni.mp3"

Online audio converters are recommended when you need fast and casual file conversions.

There are many online tools that can deal with WAV file to MP3 conversion, and CloudConvert is one of the best options. It allows you to have 10 free conversions every day and convert files as big as 1 GB. The workflow is simple:

🗨️ The biggest advantage of online converters is that you can use it on any device without installing any software. But there are clear downsides: they require a stable internet connection, the file involve waiting times for file uploads, have limits on free usage, and raise concerns regarding data privacy. Therefore, this method is recommended only for quick, one-off file conversions. For a more secure and robust conversion experience, it’s better to use the desktop programs.

WAV files are typically large in size. By converting WAV to MP3, you can significantly reduce file size and also achieve broader device compatibility.

Yes. Because MP3 is a lossy format, any conversion to MP3 will cause some loss of audio quality. In other words, it’s impossible to convert WAV to MP3 without losing quality.

Lossy conversion doesn’t mean you don’t get good output quality. In fact, converting WAV to MP3 at a bitrate of 320 kbps will have a higher quality output than regular MP3. The tools mentioned in this article can all help you easily achieve high-quality WAV to MP3 conversion.

The easiest way to convert all WAV files from a folder to MP3 format is by using a dedicated audio converter software, such as WonderFox Free HD Video Converter Factory on Windows. It allows you to import all the WAV files and process them in batches.
