Case Converter

What each button does

UPPER CASE: converts all characters to capital letters.

lower case: converts all characters to lower-case letters.

Title Case: capitalizes the first letter of most words, while keeping short connecting words (like "a", "of", "the") lowercase — the standard style for headlines and titles.

Sentence case: capitalizes only the first letter of each sentence, as in normal prose. It can't detect proper nouns, so names may need manual capitalization.

Capitalized Case: capitalizes the first letter of every single word, including short connecting words (unlike Title Case).

Inverse Case: swaps upper case and lower case for every character.

Normalized with Single/Double Space: cleans up extra or awkward whitespace, and adds one or two spaces after sentence-ending punctuation.
