Javascript: Edit ID3 tags of mp3

Question

I have a blob data of an mp3 downloaded from server using XMLHttpReqest in my web application. I want to edit the ID3 tags of the file (i.e. edit album art, genre, artist, album etc.). I checked by there are libraries that can read ID3 tags in javascript but didn't find any implementation about editing them in javascript. I want to do this in web browser, I have no option to do this on server. The server is just an external cdn server storing mp3 files.

Answer 1

This library helps writing id3 tags: https://github.com/egoroof/browser-id3-writer

Answer 2

If someone is still looking for this kind of library, mp3tag.js can read and write ID3 tags.
