MP3 Metadata Viewer
Use MP3 Metadata Viewer, review the result, and keep the original until the output is checked.
How to use MP3 Metadata Viewer
- Select one or more .mp3 files; other audio types are not accepted on this page.
- Read Title, Artist, Album, Year, Genre, Track Number and the rest of the embedded tags, plus the cover art when the file carries one.
- Open the Export tab to write the same values out as JSON, CSV or plain text, per file or for all of them at once.
- Use Compare Metadata with the two file selectors to line up two recordings side by side.
What MP3 Metadata Viewer actually does to your file
This page reads tags only - it cannot write, correct or save a modified MP3, so anything you type elsewhere will not come back here. Sample rate and channel information depend on what the browser decodes rather than the tag block, and the bitrate shown is a whole-file average (size divided by duration), which includes the tag and padding bytes. A file with no tag block at all simply lists nothing.
MP3 Metadata Viewer FAQ
What does MP3 Metadata Viewer do?
Our free MP3 metadata viewer lets you instantly read and analyze ID3 tags from your audio files. Check details like artist, album, title, genre, bitrate, and more—all online without installing software. Fast, secure, and easy to use.
Which files work with MP3 Metadata Viewer?
This category commonly supports MP3, WAV, AAC, OGG, and M4A. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Should I strip metadata before sharing?
If the file is going to a public audience, yes: remove location, device and author fields. Editing tools usually rewrite only some tags, so check the result rather than assuming.
Will my original file be changed?
No. The work is done on a copy in this tab by your browser's audio decoder and a WebAssembly build of ffmpeg, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by your browser's audio decoder and a WebAssembly build of ffmpeg, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Is the MP3 Metadata Viewer free?
Yes. The MP3 Metadata Viewer is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.
