About Audio Metadata

Audio Metadata instantly reads and displays an audio file's basic properties — name, size, MIME type, last-modified date, and duration — directly in your browser using the File and Audio APIs. Note: it currently shows file-level properties only; it doesn't read or edit embedded tags like title, artist, album, or bitrate.

How to use Audio Metadata

  1. 1Click the upload area and select an audio file.
  2. 2The tool reads the file's basic properties immediately.
  3. 3Play the file briefly so its duration can be detected and added to the list.
  4. 4Review the full property list displayed below the player.

Frequently Asked Questions

Can I edit metadata tags like title or artist?

Not currently — this tool only displays file-level properties (name, size, type, date, duration); it doesn't read or write ID3 or similar embedded tags.

What audio formats are supported?

Any format your browser can play, such as MP3, WAV, FLAC, OGG, or M4A.

Is there a batch mode?

No, one file is processed at a time.

Is my file uploaded anywhere?

No. Everything is read locally via the browser's File and Audio APIs — your file is never uploaded to a server.

Tips & Tricks

  • ✓Duration only appears after the audio starts loading — click play briefly if it's not showing.
  • ✓Use the file size and type fields to confirm you're looking at the right version of a file before sharing it.
  • ✓For editing embedded ID3 tags (title, artist, album art), you'll need a dedicated tag editor — this tool is read-only for basic properties.
  • ✓The "type" field reflects your browser's detected MIME type, which can be empty for less common audio formats.
