What is an MP3 Tag Editor?
An MP3 tag editor is a specialized tool designed to modify the metadata embedded within MP3 audio files. These metadata tags, known as ID3 tags, store essential information about your music including song title, artist name, album title, release year, genre, track number, and album artwork. Our online MP3 tag editor provides a convenient way to organize and manage your music library without installing any desktop software.
MP3 files use the ID3 tagging standard, which comes in two main versions: ID3v1 (older, limited to 30 characters per field) and ID3v2 (modern, supports unlimited text and embedded images). Our editor supports both versions, ensuring compatibility with all MP3 files and music players.

Frequently Asked Questions
What is the difference between ID3v1 and ID3v2 tags?
ID3v1 is the older tagging standard with a fixed 128-byte structure at the end of MP3 files. It supports basic fields (title, artist, album, year, comment, genre) with a 30-character limit. ID3v2 is the modern standard that supports unlimited text length, Unicode characters, multiple images, lyrics, and custom fields. Our editor supports both formats and automatically uses ID3v2 for maximum compatibility and flexibility.
Will editing MP3 tags reduce audio quality?
No, editing ID3 tags has absolutely no effect on audio quality. Metadata tags are stored in a separate section of the MP3 file, completely independent from the audio data stream. When you edit tags, only the metadata section is modified - the compressed audio remains bit-for-bit identical. This is a lossless operation that preserves your original audio quality.
Can I edit multiple MP3 files at once?
Yes! Free users can process up to 5 MP3 files simultaneously. Pro users can batch edit up to 50 files at once, making it ideal for organizing large music libraries. Batch editing allows you to apply the same metadata changes to multiple files quickly, such as setting the same album name or artist for all tracks in an album.
What image formats are supported for album art?
You can upload album artwork in JPG, PNG, or GIF formats. For best results, use square images with at least 500x500 pixel resolution. The ideal size for high-quality album art is 3000x3000 pixels, which ensures your cover looks sharp on all devices and music players. The editor automatically optimizes images for embedding in MP3 files.
Do you upload my MP3 files to your servers?
No, your MP3 files never leave your device. All metadata editing happens entirely in your web browser using JavaScript. This browser-based approach ensures maximum privacy and security - your music files remain on your computer throughout the entire editing process. We never see, store, or have access to your files.
Can I use this MP3 tag editor on my phone?
Yes! Our online MP3 tag editor is fully responsive and works on smartphones and tablets. You can edit MP3 metadata on the go using any modern mobile browser (Safari, Chrome, Firefox). The interface automatically adapts to your screen size for comfortable editing on any device.
What MP3 bitrates and sample rates are supported?
Our editor supports all MP3 bitrates (from 32 kbps to 320 kbps) and sample rates (8 kHz to 48 kHz). Whether you have low-bitrate voice recordings or high-quality 320 kbps music files, the tag editor works seamlessly. The metadata editing process is independent of audio encoding parameters.
Can I remove all metadata from an MP3 file?
Yes, you can remove all ID3 tags from your MP3 files using our editor. Simply clear all the metadata fields and remove the album artwork, then save the file. This creates a "clean" MP3 file with no embedded metadata, which can be useful for privacy purposes or when you want to start fresh with new tags.
