Online text to uppercase converter.
Case Conversion Modes

Converts all letters in the text to lowercase (small letters). This is the most commonly used mode for text unification.
Example:
- Before: "Hello, World! This IS a TEST Converter."
- After: "hello, world! this is a test converter."
UPPERCASE
Converts all letters to uppercase (capital letters). Used for text emphasis or creating headers.
Example:
- Before: "Hello, World! This is a test converter."
- After: "HELLO, WORLD! THIS IS A TEST CONVERTER."
Proper Case
Capitalizes the first letter of each word. Suitable for formatting titles, book names, and articles.
Example:
- Before: "hello, world! this is a test converter."
- After: "Hello, World! This Is A Test Converter."
Sentence case
Capitalizes only the first letter of the first word in each sentence, with all other letters becoming lowercase. This is the standard text formatting.
Example:
- Before: "hello, WORLD! this IS a TEST converter."
