Edit MP3 tags and cover art
Podcast hosts and music players show "Unknown Artist" with a gray placeholder because the MP3's ID3 tags are missing or stale. The text tags are rewritten as ID3v2.3 and your JPG/PNG is embedded as official front-cover art — the audio stream itself is stream-copied, so not a single sample is re-encoded.

Frequently asked questions
Will the audio quality change?
No — the audio is copied bit-exact; only metadata is rewritten.
What happens to an old cover inside the file?
It is replaced: the new image becomes the single attached front cover.
Can I leave some fields empty?
Yes — only the fields you fill in are written.
