AIFF to MP3 Converter
- Step 1: Add your AIF, AIFF, or AIFC files. In Expert Settings choose Auto or a fixed bitrate (320, 256, 192, 128, 96, 64 kbps), then start the upload.
- Step 2: We convert your audio to MP3 on fast servers. Big files are welcome. You can upload up to 20 files at once.
- Step 3: Download each MP3 as soon as it is ready. If you uploaded several files, download them one by one when the button shows Download.
Upload up to 20 files at once.
Batch-convert up to 20 AIFF, AIF, or AIFC files to MP3 on fast servers
Drop up to 20 AIFF, AIF, or AIFC files into Converter App and get MP3s processed in parallel on fast servers. Download each track the moment it finishes—big files welcome and no daily caps.
Auto or fixed bitrate (64-320 kbps) with smart mono handling
Start from lossless AIFF, choose Auto for mixed content, or lock 96-320 kbps for predictable sizes; mono is detected automatically. If your source is AIFC, avoid very low bitrates and stick to 192-320 kbps to prevent compounding artifacts.
Free to use
Converter App is free to use. Convert as many AIFF, AIF, or AIFC files as you need, including large files, with no sign-up and no watermarks. There are no daily limits under normal fair use.
Expected MP3 size and sound at common bitrates
A typical 3 minute AIFF (25-35 MB) becomes roughly 4.3 MB at 192 kbps, about 5.6 MB at 256 kbps, and around 6.7 MB at 320 kbps. Speech is usually clean at 96-128 kbps, while music and long fades keep detail at 192-320 kbps.
Fast batches with per-file progress and instant downloads
Queue up to 20 files, watch clear per-file progress, and grab each MP3 as soon as it's ready. Keep the tab open while Converter App powers through large projects quickly, then jump to AIFF to WAV or MP3 to WAV with the same workflow.
