Why podcasters use this ID3 editor
Podcast uploader workflow
This tool feels like a focused podcast uploader step: drop your MP3, confirm the Episode Title, Artist Name, and Podcast Name, attach cover art, and download a clean file ready for your host. No clutter, no accounts.
Accurate ID3 tags
Correct metadata helps apps display your show consistently. We write Title (TIT2), Artist (TPE1), Album (TALB), and APIC for cover art, following common ID3v2.3 conventions used by podcast players.
Private, in‑browser
Your MP3 never leaves your device. Processing runs locally in your browser, so you can edit safely even on large files without waiting for uploads.

How to tag MP3s correctly
After mixing and mastering, exporting an MP3 is only part of the job. Many podcast hosts and directories read ID3 tags to render titles and artwork. This guide ensures your files look professional everywhere.
1. The Essentials
Correct metadata acts as a portable layer that travels with the MP3. At a minimum, set the Episode Title (TIT2), Artist (TPE1), and Album (TALB, which is your podcast name).
2. Cover Art (APIC)
Always embed square cover art. Follow Apple’s guidance: a square image at least 1400×1400 pixels, ideally 3000×3000, in JPEG or PNG. This ensures your show logo appears even when the file is played offline or in barebones players.
3. The Workflow
Export the MP3 from your DAW. Open it here. Verify the Title, Artist, and Album. Embed your latest artwork. Click Write tags. This simple checklist prevents "Unknown Artist" or blank icons from appearing in listeners' libraries.
