Frequently asked questions

What metadata fields can I edit?

You can edit title, artist, album, year, genre, track number, and cover art. The tool automatically reads all existing metadata from your file.

Which audio formats are supported?

The editor works with MP3, FLAC, OGG, M4A/AAC, and WAV. MP3 files use a fast native ID3 writer; other formats use FFmpeg.

Can I add cover art to a file that doesn't have one?

Yes. Upload any image (JPG, PNG) and it will be embedded as the cover art in your audio file.

Will editing metadata change the audio quality?

No. For MP3 files, the metadata is written directly to the ID3 tags without touching the audio data. For other formats, the audio stream is copied without re-encoding.
