Audio conversion questions
Local conversion, clear choices. Here are the details.
Is this audio converter free?
Yes. Conversion is free, requires no account and uses no MusicGo credits.
Is my audio uploaded?
No. Input and converted audio stay in your browser. They are not sent to MusicGo or R2, and are not added to My works. Download the result before leaving.
Which formats can I convert?
Choose MP3, WAV, M4A, FLAC, OGG, AAC, Opus, WebM audio or AIFF as input. Output is MP3, WAV, M4A, FLAC or OGG. Browser preview support varies by format.
What is the file size limit?
One file at a time, up to 50 MB on desktop or 20 MB on mobile. The conversion engine is downloaded on first use. Processing speed depends on your device.
Will conversion improve the sound quality?
No. A higher bitrate or a lossless format cannot restore detail missing from the source. Re-encoding a lossy recording can reduce its quality.
Why are WAV and FLAC files larger?
WAV uses uncompressed 16-bit PCM. FLAC compresses audio without discarding detail, so it can still be larger than MP3. File size depends on duration, sample rate, channels and the source. A larger output does not restore lost quality.
How do I convert M4A to MP3?
Choose your M4A file, select MP3 and a bitrate, then convert. Preview the result and download the MP3 file. The same workflow works for WAV to MP3, FLAC to MP3 and MP3 to WAV.
