Free MP3 Tag Editor

Edit MP3 ID3 tags + album art online — free, private, no sign-up

SnipSound's MP3 Tag Editor reads the metadata embedded in your MP3 file (title, artist, album, year, genre, track number, comment, album art), shows it in an editable form, and lets you save a new MP3 with your changes. The whole flow runs in your browser using a vanilla-JS ID3v2 parser plus the open-source browser-id3-writer library. Your audio file never leaves your device.

How ID3 tags work

An MP3 file is mostly audio frames, but the start (and sometimes the end) of the file can carry a metadata block called an ID3 tag. ID3v1 (the original, 128 bytes at the very end) is mostly obsolete — everything modern uses ID3v2, a flexible container that can hold any number of "frames" with names like TIT2 (title), TPE1 (artist), TALB (album), TYER (year), TCON (genre), TRCK (track number), COMM (comment), and APIC (attached picture — i.e., album art).

Different players expect different ID3 versions. v2.3 is the safe choice because every major player on every OS reads it correctly — iTunes/Apple Music, Spotify Local Files, foobar2000, Windows Media Player, Android default music apps, podcast players (Pocket Casts, Overcast, Apple Podcasts), and VLC. We write v2.3 by default for that reason. We read v2.2, v2.3, AND v2.4 so you can edit files tagged by any tool.

Common use cases

How to use it (step-by-step)

1. Drop your MP3 on the page (or click to pick one).
2. The current ID3 tags are read and shown in the form. The "Show all detected tags (raw)" section below the form lists every frame the file contains — useful if your player shows tags you don't see in the standard form fields.
3. Edit any field. To add or replace album art, click the cover-art square and pick a JPG or PNG. To remove art entirely, click "Remove."
4. Click Save tags & Download. A new MP3 is generated with your changes baked into the ID3v2.3 header. The audio data is untouched — just the tag block changes.

Why use SnipSound's tag editor

• 100% in your browser. Other online tag editors (Mp3tag.de's web demo, Audio-online-convert, TagMP3) often upload your file to a server. We don't — the MP3 never leaves your device.
• Album art included. Embed a JPG / PNG cover image straight from your computer. Many free editors skip the APIC frame.
• Reads ANY ID3 version, writes the safest one. v2.2 / v2.3 / v2.4 input, v2.3 output. Maximum player compatibility.
• Raw-tag view. Most editors only show the standard form fields. We expose every frame so you can see if there are unusual tags (TXXX user-defined frames, USLT lyrics, etc.) and decide whether to keep them.
• No upload limit, no quota, no signup. Tag a 200 MB MP3 audiobook chapter — works fine.
