M4A to MP3
- Step 1: Select up to 20 M4A files or drag and drop them here. Choose a bitrate if you like; Auto is recommended for most audio. Tip: If your M4A is ALAC (lossless), keep a copy of the original.
- Step 2: The conversion starts automatically and finishes quickly. Re-encoding AAC to MP3 will not improve quality, but it will increase compatibility.
- Step 3: Click Convert, then Download. If you upload more than one file, you will receive a ZIP containing all the MP3s.
You can upload up to 20 files at once.
Batch convert up to 20 M4A files
Drag in up to 20 M4A files and Converter App will deliver your MP3s in one go. If you add more than one, we bundle the results into a single ZIP.
Fast in-browser conversion
Uploads start instantly and conversion runs on Converter App’s servers, so you finish fast. We handle large M4A files smoothly and impose no daily caps.
Free, no hidden fees
Converter App is free to use. No paywalls, no trial limits, no account required.
Quality you control
Converter App lets you choose Auto for smart results or set a fixed bitrate (320–64 kbps); music is best at 192 kbps+, podcasts at 128 kbps. If your M4A is ALAC lossless, keep a copy of the original since MP3 is always lossy.
Device-friendly MP3 output
Converter App produces standard MP3s that play in cars, phones, and older players without tweaking. Perfect when a device won’t accept AAC M4A.
Privacy respected
Your files are processed temporarily and removed automatically after conversion. No signup required.
