About converting AAC to MP3
Converting AAC to MP3 decodes the audio and re-encodes it to MP3 entirely in your browser. MP3 is small and universally playable; WAV is uncompressed and lossless.
Your audio never reaches a server. Converting an already-compressed file to a lossless format can't restore detail that was removed earlier.
Raw AAC streams play in fewer places than their quality deserves — MP3 remains the compatibility king. This decodes your AAC in the browser and re-encodes it at 128 kbps MP3. AAC is slightly more efficient per bit than MP3, so convert when a device or app demands MP3, not as an upgrade.
Frequently asked questions
How do I convert AAC to MP3?
Add your AAC file above and press Convert. FileTinker decodes and re-encodes it to MP3 in your browser, then gives you the converted file to download — nothing is uploaded.
Is my audio uploaded to convert AAC to MP3?
No. The conversion runs entirely in your browser, so your audio never leaves your device and nothing is stored on a server.
Will converting change the audio quality?
WAV is uncompressed and lossless, while MP3 uses efficient compression at a high-quality bitrate. Converting an already-compressed file won't restore detail that was removed earlier.
Can I convert several files?
Convert them one after another — each runs locally and downloads instantly, with no queue, sign-up or file-size limit.
Does AAC to MP3 lose quality?
A little, as with any lossy-to-lossy conversion — the MP3 encoder works from the decoded audio and discards some information again. At 128 kbps the result is fine for everyday listening; keep the AAC original as your better master.
