Free Case Converter
Convert your text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case and kebab-case with a single click.
What is the case converter?
A case converter is a free tool that changes the letter case of your text — for example turning it into UPPERCASE, lowercase, Title Case or Sentence case — without retyping it. You paste your text, pick a style, and it rewrites it instantly. Slashit's case converter also handles programming styles like camelCase, snake_case and kebab-case, and runs entirely in your browser so nothing is uploaded. It's a quick fix for text that came in the wrong case, headings that need title casing, or variable names that need reformatting.

Frequently asked questions
What's the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every major word (Great For Headings), while Sentence case only capitalises the first letter of each sentence (great for body text).
Does it support camelCase and snake_case?
Yes. Alongside standard cases it converts text to camelCase, snake_case and kebab-case, which is handy for code and file names.
Is it free?
