Why use this MP3 tag editor online

Edit MP3 tags online without installing anything

Desktop taggers are great for huge libraries, but for a handful of songs you shouldn’t need to install software. This MP3 tag editor online works in any modern browser on Windows, macOS, Linux, Chromebook, iPhone and Android.

Private by design: no upload

The MP3 file is opened with your browser’s File API and rewritten in memory. Nothing is sent to a server, so unreleased demos and personal recordings stay on your device. You can even disconnect from the internet after the page loads.

Lossless: the audio is never touched

An MP3 metadata editor only needs to change the tag block at the start of the file. The audio frames are copied byte for byte, so the sound and bitrate stay exactly the same.

Readable everywhere

Tags are written as ID3v2.3 with Unicode text, the version that phones, car stereos, iTunes/Apple Music, Windows, VLC and most DJ apps read reliably — so accents, Cyrillic, Chinese, Japanese and Korean titles display correctly.

Tips for clean MP3 metadata

  • Use the same spelling of an artist across every file — players group tracks by exact text.
  • Fill in Album artist for compilations and features, otherwise one album may split into many.
  • Use 3/12 style track numbers so players sort and show the album length.
  • Square cover art around 1000×1000 px looks sharp without bloating the file.
  • Keep a copy of the original MP3 until you’ve checked the new tags in your player.
