• lowercase – Converts all letters to small form.
• Title Case – Capitalizes the first letter of each word.

• Capitalized Case – Similar to title case, with precise capitalization rules for readability.

This converter is ideal for preparing content for publication, coding, writing reports, or standardizing text formats in digital documents.
