What is ID3 Tag Editor?

ID3 Tag Editor lets you edit MP3 metadata: song titles, artist names, album details, track numbers, genres, and album artwork. Your files stay private and never leave your device.

The editor reads and writes ID3v2 frames (TIT2 for title, TPE1 for artist, TALB for album, TCOM for composer, APIC for cover art, plus year, track, genre, comment, and USLT lyrics). Album art accepts JPEG and PNG up to a few MB and embeds inside the MP3 itself, so the artwork travels with the file even after copying to a USB stick or car stereo. A batch mode lets you set shared tags and apply them to up to 20 files at once, downloading them all as a ZIP.

How to use

1. Step 1 — Upload your MP3 file using the file picker or drag and drop it into the editor area.
2. Step 2 — Edit the metadata fields: title, artist, album, year, track number (e.g. 3/12), genre, composer, comment, lyrics, and album art. Use Auto-fill from filename to read artist, title and year straight from the file name, or switch to Batch to tag several files at once.
3. Step 3 — Click Save to download the updated MP3 file with your new metadata embedded.

When to use

• Renaming a podcast episode whose tags say 'track 01' so it shows up correctly in a music app.
• Adding cover art to MP3s ripped from old CDs before sending them to a phone or car.
• Fixing artist or album names after a music app imported them with the wrong characters or in capitals.

Result

You downloaded a podcast episode labeled 'track_01.mp3' with no metadata. Open it in the ID3 Tag Editor, set the title to 'Episode 42: Deep Work', artist to 'Productivity Cast', add the show's cover art, and save — your music player now displays everything correctly.

FAQ

What version of ID3 tags does this editor use?

It reads ID3v1 (old 128-byte tail), ID3v2.3, and ID3v2.4 — and saves in ID3v2.3, which is the most compatible across iTunes, Windows Media Player, Plex, and most car stereos. Tags written are visible to any modern music player.

Does editing tags change the audio quality of my MP3?

No. ID3 tags live in a separate header section of the file from the audio data. The bytes that produce sound are copied through unchanged, so bitrate, channels, and sample rate stay exactly as before — only the metadata fields are rewritten.

Can I add cover art to a song that doesn't have any?

Yes. Upload a JPEG or PNG in the Album Art slot and it gets embedded into the MP3 as an APIC frame. Square images around 500×500 px work best — they fit phone lockscreens and car displays without scaling oddly.

Why does my music app still show the old title after I saved?

Most players cache metadata from when you first imported the file. Remove the track from the library and re-add it, or refresh the library index. On iTunes this is Get Info then changing any field; on Plex use Refresh Metadata on the track.

Will the editor work on files other than MP3?

Only on MP3, since ID3 is specifically the MP3 metadata format. FLAC files use Vorbis comments, M4A uses MP4 atoms, and OGG uses its own scheme. Convert to MP3 first or use a format-specific tagger for those.
