✍️ Title Case Text Converter

  • Smart Capitalization Rules: Converts text based on Chicago Manual of Style guidelines:
    • Automatically keeps minor words (e.g., a, an, the, and, but, or, for, in, on, at, to, with) lowercase unless they begin/end a title or follow a colon, em-dash, or bracket.
    • Preserves common acronyms and music terms (e.g., DJ, EP, LP, VIP, Remix, feat., vs.).
  • Live Conversion Mode: Toggle "Live conversion" to format your text instantly as you type.
  • History Log: Keeps a local history of recent conversions in browser storage. Click any history item to reload it into the editor or copy it directly.

🔒 Privacy & Local Processing

100% In-Browser & Private: All file operations, ID3 tag editing, image processing, and title case conversions run entirely on your local machine in your web browser. Your MP3 files and metadata are never uploaded to any server.
