Frequently Asked Questions
What ID3 tags can I edit?
Title (TIT2), Artist (TPE1), Album (TALB), Year (TDRC), Genre (TCON), Track Number (TRCK), Comment (COMM), and Album Cover Art (APIC).
Is my MP3 uploaded to a server?
No. ID3 tag reading and writing is done entirely in your browser using the File API and ArrayBuffer manipulation. Your file never leaves your device.
Can I add album cover art?
Yes. Click the cover art area to upload a JPEG or PNG image. It is embedded as an APIC frame in the ID3v2 tag.
What ID3 version is used?
The tool reads ID3v2.3 and ID3v2.4 tags and writes ID3v2.3 format, which is the most widely compatible version.
Will editing tags affect audio quality?
No. Tags are metadata stored at the beginning of the MP3 file. Editing them does not touch the audio data.
