AAC to MP3 Converter
Drop in an AAC file and get back a standard MP3. The conversion runs in your browser, on your machine, with nothing uploaded anywhere.
Drop your AAC here
Raw .aac or .m4a, both convert the same way.
Converts on your device. Your file never leaves this page.
- Raw .aac streams and .m4a
- MP3 at 128, 192, or 320 kbps
- No upload, converts on-device
- Free, no sign-up, no watermark
A converter that stays out of your way.
There’s no upload bar and no sign-up wall. You get your file back as audio, and that’s the whole transaction.
AAC in, MP3 out
Drop in a AAC file and get a MP3 back with the same name. Other audio and video formats convert just as well if you have strays to deal with.
Your file stays on your machine
Most online converters upload your file to their server. This one doesn't. The work happens inside this browser tab, and closing the tab clears everything.
No sign-up, no watermark, no daily cap
Convert as many files as you like, back to back. Nobody's counting, and nothing gets stamped on the result.
Pick the quality you want
128 kbps keeps spoken word small, 192 is right for most things, and 320 holds onto every bit of detail the source has.
The stream without a home
A bare .aac file is an odd artifact: the compressed audio itself with no container around it, which is how it comes out of internet radio recorders, stream capture tools, and some broadcast software. Half your apps will play it, half will squint at it, and the file has no proper place for tags, chapters, or artwork.
MP3 solves it the boring way, with a format that has been welcome everywhere for twenty-five years. This page does the conversion in your browser, on your machine, and the recording never travels anywhere in the process.
AAC, M4A, MP4: the family resemblance
These three confuse everyone, so here’s the map. AAC is the codec, the actual compressed audio. M4A is an audio-only container that holds AAC. MP4 is the video container that holds AAC next to a video track. This page happily eats the first two, and if you hand it an MP4 it will pull the audio out of that too, though the MP4 to MP3 page tells that story properly.
Matching the bitrate
Radio and stream captures usually run 96 to 128 kbps, so a 192 kbps MP3 carries them over with headroom to spare. Higher-grade AAC, like 256 kbps files, deserves the 320 setting. The rule from every other lossy-to-lossy page on this site applies here too: the MP3 can preserve what the AAC holds, not improve on it, so pick a number at or above the source and it converts clean.
How to convert AAC to MP3
Three steps, less than a minute. No setup, no sign-up.
Drop in the AAC file
Drag it into the box above, or click Choose a file and pick it from a folder.
Pick the quality
192 kbps suits most files. Go 320 when the audio deserves it, or 128 if it's spoken word and you want it small.
Save the MP3
Hit Download and the MP3 lands with the same name as the original, ready to play or edit.
AAC to MP3 converter FAQ
Same audio, different wrapping. A .aac file is the bare compressed stream, usually from a radio recorder or a stream capture; a .m4a is that stream in a tidy container with tags. Both drop in here and come out as the same MP3.
Internet radio recorders, HLS stream captures, some voice recorders, and audio pulled out of transport streams. They play unevenly because many apps want the container, not the raw stream; converting to MP3 ends the argument.
Codec for codec, AAC is a bit more efficient, but that only matters if your player supports it. The point of converting is reach: MP3 plays on everything, and at 192 or 320 kbps the efficiency difference isn't something you'll hear.
A little in theory, as with any lossy-to-lossy step. Match or exceed the source bitrate (most AAC streams are 96 to 256 kbps, so 192 or 320 covers it) and the result is practically indistinguishable.
