Frequently asked questions
- What is the difference between ID3v1 and ID3v2 tags?
- ID3v1 is a fixed 128-byte block at the end of an MP3 file with short, limited fields. ID3v2 is modern and flexible: it sits at the start of the file, supports long Unicode text, comments, and embedded cover art. This tool reads and writes ID3v2.3 tags, which are the most widely supported format across players and phones.
- Which MP3 tags can I edit with this tool?
- You can edit the most common fields: Title, Artist, Album, Album Artist, Year, Genre, Track number (including fraction format like 3/12), and Comment. You can also add, replace, or remove the embedded cover art. The tool writes standard ID3v2.3 frames (TIT2, TPE1, TALB, TPE2, TYER, TCON, TRCK, COMM, APIC) that are recognised by iTunes, Apple Music, Windows Media Player, Spotify local files, and Android music apps.
- Can I batch edit multiple MP3 files at once?
- Not yet. This ID3 tag editor works on one file at a time so you can review and confirm each change before saving. For very large libraries, desktop tools like Mp3tag offer batch editing, but for quick fixes to a few tracks this browser tool is faster because there is nothing to install.
- Does this work on iPhone, iPad, and Android?
- Yes. The editor runs entirely in your mobile browser using standard file pickers, so you can select an MP3 from Files or your Downloads folder, edit tags, and the saved file will land back in your downloads. No app install or account is required on any device.
- Are my MP3 files uploaded to a server?
- No. All parsing, tag editing, cover art embedding, and file saving happen locally in your browser using JavaScript. Your audio never leaves your device, which means edits are fast and your music stays private even for large files.
- What cover art formats are supported?
- You can embed JPEG or PNG images as the cover (APIC frame, type 3 / front cover). For best compatibility across players, a square JPEG between 500x500 and 1000x1000 pixels works well. The existing cover is displayed when you open a file so you can keep it, replace it, or remove it entirely.
