What is a FLAC Tag Editor?
A FLAC tag editor is a specialized tool for editing metadata in FLAC (Free Lossless Audio Codec) files. Unlike MP3's ID3 tags, FLAC uses Vorbis Comments for metadata storage, which supports unlimited text fields and embedded images. Our online FLAC tag editor makes it easy to organize your lossless music library without installing desktop software.
FLAC is the preferred format for audiophiles and music enthusiasts who demand perfect audio quality. Proper tagging of FLAC files is essential for library management, as these files often represent your highest-quality music collection. Our editor supports all standard Vorbis Comment fields including title, artist, album, date, genre, and embedded album artwork.

FLAC vs MP3 Tagging
Understanding the differences between FLAC and MP3 metadata systems:
- •Metadata Format: FLAC uses Vorbis Comments, MP3 uses ID3 tags
- •Field Flexibility: Vorbis Comments allow custom fields, ID3 has predefined fields
- •Text Encoding: Vorbis Comments use UTF-8 natively, ID3v2 supports multiple encodings
- •Multiple Values: Vorbis Comments can have multiple values per field (e.g., multiple artists)
- •Case Sensitivity: Vorbis Comment field names are case-insensitive
Frequently Asked Questions
What are Vorbis Comments in FLAC files?
Vorbis Comments are the metadata format used by FLAC files. They're similar to ID3 tags in MP3 files but more flexible. Vorbis Comments support unlimited text length, UTF-8 encoding, custom fields, and multiple values per field. Common fields include TITLE, ARTIST, ALBUM, DATE, GENRE, and TRACKNUMBER.
Will editing FLAC tags affect audio quality?
No, editing metadata in FLAC files has absolutely no effect on audio quality. FLAC is a lossless format, and metadata is stored separately from the audio data. Your FLAC files remain bit-perfect after editing tags - the audio stream is never re-encoded or modified in any way.
Can I add album art to FLAC files?
Yes! FLAC files support embedded album artwork through the FLAC picture block. You can embed JPG, PNG, or GIF images directly into your FLAC files. The artwork is stored as part of the file and displays in all FLAC-compatible music players. We recommend using high-resolution square images (at least 1000x1000 pixels) for best quality.
What's the maximum file size for FLAC editing?
Our editor supports FLAC files up to 100MB for free users. This is sufficient for most FLAC files - a typical 5-minute song in FLAC format is 30-50MB. For larger files (such as long classical pieces or high-resolution audio), Pro users can process files up to 500MB.
Can I batch edit multiple FLAC files?
Yes! Free users can edit up to 5 FLAC files simultaneously. Pro users can batch process up to 50 files at once, making it ideal for tagging entire albums or large music collections. Batch editing allows you to apply the same metadata to multiple files quickly.
Do FLAC tags work in all music players?
Yes, all modern music players that support FLAC playback also support Vorbis Comments metadata. This includes VLC, foobar2000, MusicBee, iTunes (with plugins), Windows Media Player (with codecs), and most mobile music apps. The tags are part of the FLAC specification and universally supported.
