Case Converter
A case converter rewrites text in a different capitalisation style — turning a shouty ALL-CAPS heading into calm sentence case, or a phrase into camelCase for code. FreeToolsKit's converter produces eight styles at once, updating live as you type, each with its own copy button. Your text stays in your browser; nothing is uploaded.

Key takeaways
- Eight styles are generated at once: UPPER, lower, Title, Sentence, aLtErNaTiNg, camelCase, snake_case and kebab-case.
- Every style updates live as you type or paste, and each has its own one-click copy button.
- Title Case capitalises each word; Sentence case capitalises the start of each sentence and leaves the rest lower case.
- The input's character and word counts are shown so you can track length while you edit.

- Look at the eight converted versions, which update as you type.
- Find the style you need — for example Title Case for a heading.

- Paste it wherever it needs to go.
What is the Case Converter used for?

- Turning a product list into clean, consistent Title Case headings.
- Generating variable names in camelCase or constants in snake_case while coding.
- Creating URL slugs in kebab-case from article titles.

Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word (“The Quick Brown Fox”). Sentence case capitalises only the first letter of each sentence and keeps the rest lower case (“The quick brown fox”). Headings usually use Title Case; body text uses sentence case.
How are camelCase, snake_case and kebab-case different?
camelCase joins words with each new word capitalised and no separators (myVariableName). snake_case joins with underscores (my_variable_name). kebab-case joins with hyphens (my-variable-name) and is common in URLs and CSS class names.
Does the converter change anything besides capitals?
Letters keep their content — nothing is reworded. For camelCase, snake_case and kebab-case, spaces and punctuation between words are replaced by the style's joining rule, and stray symbols are dropped so the result is a valid identifier or slug.
Is my text stored anywhere?
No. Conversion is simple string processing inside your browser. Your text is never uploaded, stored or shared.
