How to Edit Audio File Metadata and ID3 Tags
Edit title, artist, album, genre, year, and cover art metadata in MP3, FLAC, and other audio files. Fix mislabeled tracks in your music library.. This step-by-step guide walks you through the process using LevnTools Audio Metadata Editor, a free browser-based tool that handles everything locally on your device. No software to install, no account to create, and no files uploaded to external servers. Follow these steps to complete the task in under a minute — updated for 2026.
Upload your audio file
Upload the audio file whose metadata you want to edit. The tool reads existing ID3 tags for MP3, Vorbis comments for OGG and FLAC, and iTunes-style atoms for AAC and displays all current metadata fields.
Edit the metadata fields
Modify any metadata field including title, artist, album, album artist, track number, genre, year, and comments. Upload a new album cover image in JPG or PNG format to embed as the cover art.
Review all changes
Check the before-and-after comparison of all modified fields. Verify that artist names and album titles are spelled correctly as metadata is displayed by all music players and streaming library software.
Save and download
Click Save to write the updated metadata to the file. The audio content is not re-encoded — only the metadata tags are modified. Download the file with its corrected tags for your music library.
Pro Tips
- Use consistent capitalization for artist and album names across your entire library. Title Case is the standard convention for English-language music metadata.
- Embed album art at 500x500 pixels in JPEG format for the best balance of image quality and file size. Larger art increases the audio file size unnecessarily.
- Fill in the Album Artist field for compilations and collaborations. This groups tracks correctly in music players that organize by album artist rather than track artist.
Common Issues & Fixes
Issue: The metadata changes do not appear in my music player.
Fix: Most music players cache metadata. Remove the old file from your library, clear the cache, then re-import the updated file. On iTunes, right-click the library and choose "Get Info" to refresh.
Issue: The cover art is not displaying on certain devices.
Fix: Some devices only support embedded JPEG art up to 600x600 pixels. Resize your cover art to 500x500 JPEG and re-embed it. Avoid PNG format for cover art in MP3 files.
Issue: Metadata from a previous edit is being overwritten.
Fix: The tool shows all existing metadata before editing. If tags appear empty, the source file may use a different tag format. Try uploading the file again and check if it has ID3v1, ID3v2, or APE tags.
