Metadata Editor — MP3/MP4 Tags (ID3, MP4, Vorbis)

What is the Metadata Editor?

MP3stack lets you edit media tags—title, artist, album, year, genre, track/disc, and cover art—then export a clean copy. We support ID3v2 for MP3, MP4 atoms for M4A/MP4, and Vorbis comments for OGG/FLAC (when available).

Edits apply to the exported file you download; we don’t permanently store files. Use only for your own content or with permission.

Need to cut audio first? Try the Trim Audio tool. Want to combine audio/video? Use Merge Audio & Video. To add lyrics or captions, check the Subtitles Downloader.

How to use

Paste a public audio/video link or search a title/artist, then press Search.
Open Preview and go to the Metadata tab.
Edit fields: Title, Artist, Album, Album Artist, Year/Date, Genre, Track/Disc, and replace cover art (when available).
Choose output format (MP3/M4A/OGG/FLAC/MP4) and save.
Click Download to get the tagged file.

For older car stereos/players, choose ID3v2.3. For modern apps, ID3v2.4 is fine. See also 320kbps MP3 for high-quality audio.

What you can convert

Exact fields/artwork limits depend on the target format and the player reading the file.

FAQ

Which fields can I edit?

Title, Artist, Album, Album Artist, Year/Date, Genre, Track/Disc number, and cover art (when supported).

Will this overwrite my original file online?

No. Edits apply only to the exported copy you download.

ID3v2.3 or ID3v2.4—what should I pick?

v2.3 is safest for older devices (cars/stereos). v2.4 is fine for modern apps.

Why doesn’t my player show the new cover?

Many players cache artwork. Rename the file or clear cache and re-import.

Any size limits for artwork?

Large images may be resized for compatibility. JPEG is most widely supported.

Can I edit video tags (MP4)?

Yes, common fields like title/artist/album/cover in MP4 atoms are supported—reading depends on the player.

Can I normalise loudness?

ReplayGain/normalise tags can be stored; effect depends on the player.

How to fix weird characters in tags?

Use UTF-8/Unicode and ensure your player supports it. For legacy MP3, pick ID3v2.3 if necessary.

Troubleshooting

Tags not visible: try ID3v2.3 for MP3, or save as M4A for some Apple devices.
Artwork missing: use JPEG ≤ 1200px; re-import in the player.
Garbled characters: ensure UTF-8 is active; avoid unusual symbols in Title.
Download didn’t start: allow pop-ups; click the final Download.
