Case Converter
Convert text to UPPERCASE, lowercase, Title, Sentence, camelCase, snake_case or kebab-case.
Seven text cases in one click
The Case Converter rewrites your text into any of seven common formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case and kebab-case. Paste your text, press a button, and copy the result. It is handy for headings, code identifiers, file names and fixing text that arrived in the wrong case.
Programmer cases explained
camelCase joins words and capitalises each one after the first
(myVariableName). snake_case joins words with underscores
(my_variable_name), and kebab-case joins them with hyphens
(my-variable-name) — the style used in most URLs and CSS class names.

Frequently asked questions
What is Sentence case?
It lowercases everything, then capitalises the first letter of each sentence, so “hello. how are you?” becomes “Hello. How are you?”.
How is Title Case decided?
Every word gets its first letter capitalised. This simple style does not skip small words such as “of” or “the”.
Do camelCase, snake_case and kebab-case handle multiple lines?
Yes. Each line is converted independently, so your line breaks are preserved in the output.
Is my text sent anywhere?
No. All conversion happens locally in your browser and nothing is stored.
