Podcast Audio ID3 Metadata Tagger
An MP3’s ID3 tags — title, artist, album, episode number, cover art, description — determine how a podcast episode actually displays in a listener’s app, and getting them wrong (or leaving them blank) means an episode showing up as “untitled” or with the wrong artwork in someone’s feed. This tool lets you view and edit an audio file’s ID3 tags directly: set the episode title, podcast/album name, track number, embed cover art, and add a description, then export the file with the updated metadata baked in.
Podcast episodes are frequently tagged before they’re publicly released — while an episode is still being prepped, embargoed, or scheduled — so the file itself, along with its title and description, can reveal upcoming content ahead of a planned release. There’s no reason that needs to pass through a server just to update metadata fields; the tagging happens directly on the file in your browser, and the audio content itself is never transmitted anywhere in the process.
Upload your MP3 (or other tag-supporting format), and the tool reads any existing tags so you can see what’s already set before editing. Update title, artist/podcast name, album, track/episode number, and genre as needed, and upload cover art to embed directly in the file if it doesn’t already have artwork — most podcast platforms display embedded artwork automatically once the file is uploaded with it attached, rather than requiring separate artwork upload through the platform.
FAQ
Why does my episode show the wrong or no artwork in some podcast apps even after I embedded it?
Some platforms prioritize artwork set at the show/feed level over what’s embedded in individual episode files, so embedded per-episode artwork may not display everywhere depending on how a given app handles the hierarchy between feed-level and episode-level images.
What’s the difference between ID3v1 and ID3v2 tags, and does it matter which I use?
ID3v2 supports far more fields (including embedded artwork) and longer text, and is what virtually all modern podcast platforms and players expect — ID3v1 is an older, more limited format mostly kept around for compatibility with very old software, so ID3v2 is the right choice for podcast files in essentially all current situations.
Can I batch-edit tags across multiple episode files at once, like setting the same podcast name on every episode?
Yes — shared fields (podcast/album name, artist, genre) can be applied across multiple uploaded files simultaneously, while episode-specific fields like title and track number are still set individually per file.
Once tagging is done, if you also need to pull the raw audio out of a video recording of the episode rather than starting from an audio file, the Audio Track Extractor handles that separation first.
