HOW IT WORKS
1
Drop the aac file
Drag your AAC onto the page or click to browse. It is read locally, never sent anywhere.
2
Choose MP3 and bitrate
Pick 128, 192, 256 or 320 kbps. 192 kbps is the default. Click Convert to start processing in this tab.
3
Save the mp3
The finished MP3 downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Server converters receive your aac on their disk. This one reads it in your browser and nowhere else.
Local conversion
The mp3 starts encoding the moment you drop the file - there is no upload phase at all.
No account, no daily cap
Convert every aac you own, free. Nobody meters you, nobody asks for an account.
The two formats, briefly
| AAC | AAC is a lossy audio codec. This page writes a standalone AAC file using the selected bitrate. | |
|---|---|---|
| MP3 | MP3 is a lossy audio format. This converter encodes it at the selected bitrate rather than copying the original audio stream. | |
When you need this
- Use MP3 when your receiving app or player does not accept AAC. This page re-encodes the audio, so keep the original and check the download in that app before replacing it.
AAC vs MP3: what changes

Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.

Why convert AAC to MP3?+

Which quality should I pick?+
The audio bitrate choices are 128, 192, 256 and 320 kbps, with 192 kbps as the default. Lower bitrates usually reduce size but can make loss more audible.
Does converting AAC to MP3 lose quality?+
This export uses lossy audio encoding. The source AAC may contain different codecs or recording quality; re-encoding cannot improve the original. Compare the result before deleting the source.
Is there a file size limit?+
The hard cap is 2 GB per file. The practical limit is your device: conversion runs in its memory, so very large files can fail on phones with little free RAM. There is no server-side cap because nothing is uploaded.
Does my file get uploaded anywhere?+
No. The file is read and converted by code running in this browser tab. Your file is never sent to a server - its contents stay in this tab.
