🔠 Case Converter
Eight conversions run on whatever text you paste: UPPER, lower, Title, Sentence, camelCase, PascalCase, snake_case and kebab-case. There is no file field and no network call — the textarea, the buttons and the output box are the entire tool, so the text never leaves the tab. Title Case here raises every word, including short ones like of and the.

Detailed User Guide
Convert between common text cases
Switch between UPPERCASE, lowercase, Title Case, Sentence case, and programming styles like camelCase and snake_case with one click.
Title Case vs Sentence case
Title Case capitalizes every major word (for headings), while Sentence case capitalizes only the first word (for body text). Pick the one that fits your context.
Programming cases for identifiers
camelCase and snake_case are conventions used in code. This tool converts names between them, which helps when porting code between languages.
Instant, local, and private
Conversion happens entirely in your browser, so no text is uploaded anywhere.
Avoids manual retyping errors
Rather than retyping a long string in a different case, paste it and convert — eliminating typos and saving time.
Headlines benefit from Title Case
Turning a lowercase headline into Title Case improves readability and gives a polished look for article titles, email subjects, and section headings.
Batch-convert many headings at once
Paste a whole list of headings and convert them all in one pass, keeping formatting consistent across a page of section titles without editing each one by hand.
