Convert letter case without retyping

Paste or type text once, then switch instantly between uppercase, lowercase, title case and sentence case. The converted result updates as the text or selected mode changes, ready to copy into a document, spreadsheet, form or publishing system.

Uppercase and lowercase change every letter while retaining punctuation and spacing. The practical title-case option capitalises each word, while sentence case capitalises the first letter at the start of the text, after sentence-ending punctuation and on a new line.

camelCase, PascalCase, snake_case and kebab-case

Coding-style conversions treat spaces and common punctuation as separators. camelCase starts with a lowercase word and capitalises later words; PascalCase capitalises every word. snake_case joins lowercase words with underscores, while kebab-case uses hyphens.

These are general transformations rather than language-specific identifier validators. A programming language, database or naming convention may impose additional restrictions on symbols, reserved words or leading numbers.

Converting “hello world”

Title Case: Hello World

camelCase: helloWorld and PascalCase: HelloWorld

snake_case: hello_world and kebab-case: hello-world

Useful for writing, data and development

Case conversion can clean headings copied from capitalised documents, prepare spreadsheet labels, standardise filenames and turn plain phrases into common code naming styles. The title-case rule is deliberately straightforward; publishers and style guides can use different rules for short words, names and hyphenated terms.

All conversion happens locally in the browser. The text does not need to be submitted to an external conversion service, although anything copied is placed on your device clipboard in the usual way.

FAQs

Questions about the case converter

What is a case converter?

It changes the capitalisation or word-separator style of text without requiring you to retype it.

Does Title Case follow every publishing style guide?

No. This tool uses a practical rule that capitalises each word. Editorial styles may keep certain short words lowercase or apply special rules to names.

What is the difference between camelCase and PascalCase?

camelCase begins with a lowercase word, while PascalCase capitalises the first word as well. Both join the words without spaces.

How are punctuation and multiple spaces handled?

Text-oriented cases preserve spacing and punctuation. Coding cases use common punctuation and repeated spaces as word separators.

Is my text uploaded?
