About audio metadata
Metadata (tags) store information like title, artist, album, and comment inside the audio file. Players and libraries use these to display track info and organize your music. This tool lets you set or change these tags. With Same as input, the audio stream is copied without re-encoding so quality stays the same and processing is fast.
Best practices
- Use consistent naming for artist and album so your library sorts correctly.
- Fill in title and artist at minimum so tracks are identifiable in players and playlists.
- Use the comment field for notes, credits, or source info if your player supports it.
- Keep a backup of the original file if you are editing rare or important recordings.
- After editing, use the result waveform to confirm the file still plays and tags appear in your player.
Common use cases
- Fix missing or wrong tags — Correct title, artist, or album after ripping or downloading.
- Organize a music library — Add consistent tags so albums and artists display correctly.
- Podcast or voice files — Set title and artist so episodes show up properly in apps.
- Multiple passes — Edit one file at a time; no re-upload needed for several saves.
- Prepare for sharing — Add proper credits or description in the comment field before sharing.
Why use this metadata editor
This editor runs entirely in your browser. Your audio is never uploaded to any server, so your files and privacy stay on your device. You get a waveform preview to confirm the file, play from any point, and a clear summary of which tags will be written. With Same as input, the audio stream is copied — quality is unchanged and processing is quick.
Powered by Web Audio API and optimized processing.
Frequently asked questions
Does editing metadata re-encode the audio?
Not with Same as input — the tool uses stream copy: only tag data is updated. Choosing another output format re-encodes the audio.
Is my audio secure?
Yes. All processing happens in your browser. Your files are never uploaded to any server.
Which tags can I edit?
You can set or change title, artist, album, and comment. Only the fields you fill are written. The tool works with ID3 (MP3) and similar tag formats in M4A, OGG, and others.
Can I preview the file before downloading?
Yes. After writing metadata, a result waveform is shown so you can play the file and confirm. Then download when ready.
What audio formats are supported?
Common formats: MP3, M4A, AAC, WAV, OGG, FLAC, and more. With Same as input, output keeps the same format; only metadata is updated.
