Popular Use Cases

  • 🩹 Fix "Track 01 — Unknown Artist" files from old rips and downloads
  • 🖼️ Add album cover art so songs show beautiful artwork on phones and car screens
  • 📚 Organize audiobooks and lectures with proper titles and album grouping
  • 🎧 Clean up a DJ collection — consistent artist names and genres across playlists
  • 🎁 Prepare personalized music gifts with custom titles and comments
  • 📻 Tag podcast episodes with episode numbers before publishing

Pro Tips for a Clean Music Library

  • Square art wins: use 500×500 to 3000×3000 px JPG/PNG covers — players crop anything else.
  • Consistent artists: pick one spelling ("DJ Alok" vs "Dj Alok") or playlists split into duplicates.
  • Track numbers as 3/12: including the total helps some players sort multi-CD albums correctly.
  • Old cache: if a player still shows old tags, it cached metadata — remove/re-add the file or refresh its library.
  • Not an MP3? Convert M4A/FLAC/WAV to MP3 first with our Audio Converter, tag it here, then trim intros with the Audio Cutter.
  • The download keeps original audio bitrate — check it with any player's file info to confirm.

Frequently Asked Questions

Load your MP3 above, edit the title, artist, album or any other field, and press Save Tags & Download. It's completely free — no registration, no watermarks, no software installation, and unlimited files.

After loading your song, click "Upload New Image" in the Cover Art panel and pick a JPG or PNG. The image is embedded inside the MP3 file itself, so every player — phone, car, computer — displays it automatically.

ID3 is the standard metadata block embedded in MP3 files. It stores the title, artist, album, year, genre, track number, comment and cover art your music app displays. This tool writes modern ID3v2 tags that all popular players understand.

Not here. The editor copies your audio data byte-for-byte and only rewrites the metadata block — there is no re-encoding, so the sound is bit-identical to the original. Your original file is never modified either.

The file simply has empty or missing ID3 tags — common with recordings, YouTube rips and very old MP3s. Load it here, fill in the correct details, save, and every player will show the right information from then on.

MP3 files with ID3 tags are fully supported for reading and writing. Have M4A, FLAC or WAV? Convert to MP3 with our free Audio Converter first, then tag it here.

No. Reading and writing tags happens entirely in your browser with JavaScript. Your files cannot be transmitted, stored, or seen by anyone — safe for your entire music library.

Yes — pick a file, edit tags and download, all from mobile browsers. Downloads save to your Files app. Editing tags on your phone means the fixed file is ready to copy into your music folder immediately.
