The cases it makes
- UPPER CASE / lower case — the two everyone needs, for shouting or calming things down.
- Sentence case & Title Case — capitalise the first letter of each sentence, or of every word.
- camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case — the programmer naming styles, split intelligently even from messy input.
- aLtErNaTiNg and InVeRsE — for memes and for flipping the case of text you already have.
About this tool
Whether you pasted a title in ALL CAPS, need a variable name from a label, or just want your heading to look right, retyping is a waste. This converter shows all twelve styles at once and copies any of them with one click.
The programmer cases are smart about word boundaries: myVariableName, my-variable name and MY_VARIABLE_NAME all break into the same words, so you can convert between any of them cleanly. It's 100% in-browser — paste a whole paragraph if you like, nothing is uploaded or saved.
FAQ
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word (Great For Headings), while Sentence case only capitalises the first letter of each sentence (Great for body text). Both are one click here.
What is camelCase vs snake_case vs kebab-case?
They are programmer naming styles for the same words: camelCase joins words and capitalises each after the first (myVariableName), snake_case joins them with underscores (my_variable_name), and kebab-case joins them with hyphens (my-variable-name).
