Online text converter - sentence case
Case conversion modes
Lowercase
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 Converter TEST."
- After: "hello, world! this is a converter test."
UPPERCASE
Converts all letters to uppercase (capital letters). Used to emphasize text or create headings.
Example:
- Before: "Hello, World! This is a converter test."
- After: "HELLO, WORLD! THIS IS A CONVERTER TEST."
Proper Case
Capitalizes the first letter of each word. Suitable for formatting headings, book titles, and article titles.
Example:
- Before: "hello, world! this is a converter test."
- After: "Hello, World! This Is A Converter Test."
Sentence case
Capitalizes only the first letter of the first word in each sentence, while all other letters become lowercase. This is the standard text formatting.
Example:
- Before: "hello, WORLD! this IS a CONVERTER test."
- After: "Hello, world! This is a converter test."
iNVERSE cASE
Reverses the case of each letter: uppercase becomes lowercase, lowercase becomes uppercase.
Example:
- Before: "Hello, World! This IS a CONVERTER test."
- After: "hELLO, wORLD! tHIS is A converter TEST."
rAnDoM CasE
Randomly makes letters uppercase or lowercase. Can be used to create a creative or ironic effect.
Example:
- Before: "Hello, World! This is a converter test."
- After: "hElLo, WoRld! ThIs iS A cOnVeRtEr TeSt."
