Does this tool re-encode my MP3 file?

No. The tool performs 'tag surgery' by stripping the old ID3 header and writing a new one. The actual audio data is completely untouched, guaranteeing zero quality loss.

Is my audio file uploaded to a server?

Absolutely not. All processing happens locally in your browser using JavaScript. Your files never leave your device.

About This Tool

Edit the metadata of your MP3 files directly in your web browser without sending your music to an external server. Whether you are fixing missing artist names, adding album art, or organizing your local music library, this tool handles your files locally. Unlike traditional tag editors that require bulky desktop software or force you to upload your unreleased tracks to sketchy websites, our editor processes everything via client-side JavaScript. This gives you instant results without re-encoding or degrading your audio quality. Privacy remains absolute because your files never leave your device.
