Top 5 Leading AIFF-to-MP3 Converters With Quick Guides

AIFF files store uncompressed PCM audio, delivering excellent sound quality. However, its large file sizes make it inconvenient for smartphones, portable players, and online sharing. Meanwhile, MP3 uses a lossy compression to create smaller files with broader compatibility. In this post, we will introduce the best AIFF-to-MP3 converters available. These tools can help you properly decode AIFF audio and re-encode it to MP3. The best way to convert AIFF to MP3 is to use a dedicated offline audio converter.

Part 1. TopVox All Music Converter

TopVox All Music Converter is primarily for downloading and converting soundtracks from music streaming services. Due to high usage, it expanded and upgraded its service by adding a Format Converter. With it, you can decode lossless AIFF to MP3, FLAC, WAV, M4A (AAC), and M4A (ALAC). It can process hundreds of files simultaneously without experiencing lag or sudden crashes. It adopts the most advanced hardware-accelerating media processing to achieve 35× speed.

Step 1. Download the TopVox All Music Converter and complete the installation.

After setting up TopVox, go to the Tools tab and select the Format Converter.

Step 2. Drop the AIFF sources or click +Add Files to load them. This AIFF-to-MP3 converter does not limit the number of files or the sizes you can convert, so you can import multiple files.

Step 3. Head to the Output Format picker of the Format Converter and select MP3. Specify the output folder, then click Convert All to start the conversion.

We evaluate TopVox capabilities in terms of batch conversion support, processing speed, and output quality. We use 100 AIFFs, totaling 1.1 GB, as source files for conversion. In our test, the AIFF-to-MP3 conversion was completed in just 1 minute and 14 seconds.

Part 2. Audacity

Audacity is a time-tested open-source audio-only recording and editing software. Aside from recording and editing, you can use it to convert AIFF to MP3 for free. What’s surprising is that the process is quick and easy; all you need to do is import and export.

To convert: Import the AIFF files to Audacity, then click File, and select Export Audio. Choose where you would like to export: Share to audio.com or Export to computer. In the Export Audio window, go to Format, select MP3 Files, and click Export to save.

Part 3. VLC Media Player

VLC Media Player is an established media player that has been around for years. Without exploring it, you would expect it to be only for playing media files. Many didn’t know that there’s a hidden Convert/Save tool in the Media tab that can transfer AIFF to MP3 container.

To convert: Go to Media and click Convert/Save to open the Open Media window. Click +Add to import the AIFF files, then click Convert/Save to proceed. In the Convert window, go to Profile and select Audio - MP3, then click Start to convert.

Limitations: VLC can convert files, but only a few. Although it supports batch processing, it lags and eventually crashes midway when processing multiple large files.

Part 4. CloudConvert

CloudConvert is a long-running online media and file conversion service that supports hundreds of formats. As an online tool, it can convert AIFF to MP3 on Mac, Windows, and even on mobile phones. It can also convert other lossless audio formats, including WAV to MP3.

To convert: Using a browser, go to CloudConvert and click Select File to add AIFF sources. Select MP3 as your output, click Convert, and download each right after.

Limitations: CloudConvert is only recommended for processing a few non-sensitive files. Using this software requires uploading the file to a remote server, over which you have no control.

Part 5. iTunes

iTunes is a well-known media player, media library, and mobile device management platform. It is used to buy, play, and organize DRM-protected audio (see here for the meaning of DRM). You can also use it to move AIFF to MP3, and the process is uncomplicated.

Step 1. Open iTunes on your Windows computer, click Edit, and select Preferences. In the General Preferences, click the Import Settings option.

Step 2. In the Import Settings window, set the import encoder to MP3 Encoder, then click OK. Highlight the AIFF files from your library, click Convert, and select Create MP3 Version.

Limitations: iTunes always creates a new copy of the original file after conversion. Also, it cannot encode files protected by DRM to the MP3 format.

Guide: How to Choose the Right AIFF-to-MP3 Converter

Choosing a converter depends less on the number of supported formats and more on how you plan to use it. Below is a quick checklist on how to choose the right AIFF-to-MP3 converter:

1. Consider your Privacy: When you have highly private or sensitive files, choose an offline converter so your files remain on your computer.

2. File/Library Size: for 1-5 AIFF files, an online converter should be sufficient. If you’re handling 50+ files, choose software with batch processing and queue management.

3. Audio Bitrate Threshold: MP3 bitrate depends on how much quality you want to retain:

• Choose 128 kbps when your priority is to minimize the file size.
• Use 256 kbps for reasonable sound quality and storage efficiency.
• Set the bitrate to 320 kbps to minimize the compression when converting it from AIFF.
