Know what changes
M4A may contain lossy AAC or lossless ALAC audio. Conversion to MP3 is lossy either way. Protected or encrypted files are not supported; changing the extension alone does not convert audio.
Output metadata and cover art are removed. Your original file is never overwritten.
Understand bitrate and file sizeA few useful answers
Is this really free?
Yes. No account, subscription, or daily conversion quota. Each job is limited to 100 MB of input and 20 minutes of media to reduce memory failures.
Does my file get uploaded?
No. The website delivers the processing code to your browser. Your selected media and results remain on your device. The output lasts in the tab until you clear it or leave; download it before then.
Why did a conversion fail?
A file extension does not guarantee its codec is supported. Corrupt files, protected media, missing audio, low memory, or an interrupted engine download can fail. Try a smaller recording and a current browser. We do not silently send failed files to a server.
Can I use a YouTube or other media URL?
This tool accepts files from your device. It does not download from third-party websites. Use recordings you own or have permission to process.
