Text Case Converter: Uppercase, Lowercase & Title Case Tool
What is Text Case Conversion?
Text case conversion changes the capitalization of letters in text. Common conversions include UPPERCASE (all capitals), lowercase (all small letters), Title Case (capitalizing first letter of each word), and Sentence case (capitalizing first letter of sentences). Essential for formatting, coding, data processing, and content creation.
Types of Case Conversions
Our tool supports multiple text case transformations:
- UPPERCASE
Converts all letters to capital letters. Used for headings, acronyms, emphasis, and constant variables in programming (e.g., API_KEY, MAX_VALUE).
- lowercase
Converts all letters to small letters. Common in email addresses, URLs, hashtags, and variable names in some programming languages.
- Title Case
Capitalizes the first letter of each word. Standard for book titles, headings, article titles following AP or Chicago style guides.
- Sentence case
Capitalizes only the first letter of each sentence. Natural reading style for body text, descriptions, and normal prose.
Common Use Cases
Text case conversion has many practical applications:
- Content Writing: Format article titles, headings, and proper nouns according to style guides
