Music Metadata Editor - Online ID3 Tag Viewer & Writer

An ID3 tag is a metadata container embedded within MP3 audio files. It stores information like the song title, artist, album, year, genre, track number, and even album artwork. ID3 tags help music players and streaming services display accurate song information. There are two main versions: ID3v1 (simple, fixed-length, stored at the end of the file) and ID3v2 (flexible, stored at the beginning, supports more fields and album art).

Absolutely. This tool works entirely in your browser using client-side JavaScript. Your MP3 files are never uploaded to any server. All processing — reading ID3 tags, editing metadata, and generating the modified file — happens locally on your device. Your privacy and data security are fully protected.

Yes! This tool performs lossless metadata editing. It only modifies the ID3 tag portion of your MP3 file — the actual audio data remains untouched and is not re-encoded. This means your audio quality is preserved perfectly, and the process is fast even for large files.

You can edit all common ID3 fields: Title, Artist, Album Artist, Album, Year, BPM, Track Number (with total tracks), Disc Number, Genre, Composer, Publisher/Label, Comment, Lyrics, and Album Cover Art. The tool writes ID3v2.3 tags for maximum compatibility with music players, smartphones, and car audio systems.

You have several options: click the album art area to browse for an image, use the "Change" button, paste an image from your clipboard (Ctrl+V or Cmd+V while focused on the cover area), or drag and drop an image onto the cover preview. Supported formats include JPEG, PNG, and WebP. The artwork is embedded directly into the MP3 file as part of the ID3v2 tag.

ID3v1 is an older standard (introduced in 1996) that stores 128 bytes of metadata at the very end of an MP3 file. It has fixed field lengths (30 characters for title, artist, album; 4 for year; 30 for comment) and only supports 128 predefined genres. ID3v2 is the modern standard stored at the beginning of the file, supporting unlimited field lengths, Unicode text, album artwork, lyrics, BPM, and many more fields. This tool generates ID3v2.3 tags for broad compatibility.

Incorrect metadata usually occurs when ID3 tags are missing, incomplete, or contain conflicting information between ID3v1 and ID3v2 tags. Some players prioritize one version over the other. Use this tool to clean up and standardize your tags — the downloaded file will have consistent, accurate ID3v2.3 metadata that most modern players recognize correctly.

This online tool is designed for editing one file at a time with precision. For batch editing dozens or hundreds of files, dedicated desktop software like Mp3tag, MusicBrainz Picard, or Kid3 may be more efficient. However, for quick, high-quality edits to individual tracks — especially when you need album art management — this browser-based tool is fast and convenient.

BPM stands for Beats Per Minute — it measures the tempo of a song. DJs, music producers, and fitness instructors use BPM to organize playlists and mix tracks. Including BPM in your music metadata helps DJ software (like Serato, Traktor, or rekordbox) automatically categorize your tracks by tempo for seamless mixing.

Yes! The tool outputs ID3v2.3 tags with UTF-8 encoding, which is the most widely supported format across all devices and platforms — including iPhones, Android phones, Windows, macOS, Linux, car audio systems, smart speakers, and portable MP3 players. Album art is embedded as JPEG for maximum compatibility.
