Frequently Asked Questions
What are ID3 tags?ID3 tags are metadata fields embedded inside MP3 files. They store information like the song title, artist name, album name, year of release, genre, and track number. Music players and streaming apps read these tags to display song information while it's playing.
Does editing ID3 tags affect the audio quality?
No. ID3 tags are stored separately from the actual audio data in the MP3 file. Editing them has absolutely no effect on sound quality or volume — only the text metadata changes.
What ID3 tag fields can I edit?
This tool supports the most common ID3v2 fields: Title, Artist, Album, Album Artist, Year, Genre, Track Number, and Comment. These cover the vast majority of what music software displays and uses for organization.
Does my MP3 get uploaded to your servers?
No. This tool processes everything locally in your browser using JavaScript. Your MP3 file is read by your browser directly from your computer, the tags are modified in memory, and the result is downloaded back to you. No data leaves your device.
Will this work on large MP3 files?
Yes. Since processing is local, file size limits are determined by your browser and available RAM rather than server quotas. Most MP3 files (even long albums or podcasts) are processed instantly.
What if my MP3 doesn't have any tags yet?
That's fine. If the MP3 has no existing ID3 tags, all fields will appear blank. Simply type in the information you want, click Save, and the tags will be added to the file.
Can I edit multiple MP3 files at once?
This tool is designed for single-file editing to keep the interface clean and simple. For each file, upload it, make changes, and download. For bulk editing, a desktop application like Mp3tag (free, Windows) would be the better choice.
My music player still shows the old tags after editing. Why?
Music players often cache metadata. Try removing the file from your library and re-adding it, or clear the player's library cache. The file itself will have the updated tags — it's a display refresh issue on the player side.
