What Is a Case Converter?

A case converter is an online text transformation tool that instantly changes how letters appear — from uppercase to lowercase or vice versa. It automatically modifies capitalization rules according to your selection.

Here are the most common types of conversions you can make:

UPPER CASE: Converts every letter to capital form.
Example: This is a demo. → THIS IS A DEMO.
lower case: Converts all text to small letters.
Example: This is a Demo. → this is a demo.
Sentence case: Capitalizes the first letter of each sentence.
Example: welcome to the tool. it’s easy to use. → Welcome to the tool. It’s easy to use.
Title Case: Capitalizes major words while keeping small connecting words lowercase.
Example: the quick brown fox jumps over the lazy dog → The Quick Brown Fox Jumps Over the Lazy Dog
aLtErNaTiNg CaSe: Alternates between lowercase and uppercase letters.
Example: Case converter → cAsE cOnVeRtEr
Inverse Case: Swaps each letter’s case — uppercase becomes lowercase and vice versa.
Example: HeLLo → hEllO
Reverse Text: Flips your entire text backward.
Example: Hello world → dlrow olleH
