Frequently Asked Questions
What formats can I convert from and to?
You can open MP3, WAV, M4A, FLAC, OGG and other common formats, and convert to MP3 or WAV.
Does converting affect audio quality?
Converting to a lossy format like MP3 at a lower bitrate can slightly reduce quality; converting to WAV preserves the full quality of the source.
Is my file uploaded to convert it?
No — conversion happens entirely in your browser, and your file is never sent to a server.
Can I convert multiple files at once?
Each file is converted one at a time — open your next file to convert it the same way.
Do I need to install any software?
No. MP3 Converter works entirely online, in any modern browser.
