About this case converter
This free case converter changes the capitalisation of your text into nine common formats at once. Writers use Title Case and Sentence case for headlines and body copy; developers use camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE for variable names, file names and constants. Just paste your text once and copy whichever format you need — no signup, no ads in the editor, and nothing is uploaded.
Frequently asked questions
- How do I convert text to uppercase or lowercase?
- Paste into the box above — every format updates instantly. Press Copy next to the one you need.
- What's the difference between snake_case, kebab-case and camelCase?
- snake_case uses underscores (my_variable), kebab-case uses hyphens (my-variable), camelCase has no separator and capitalises each word after the first (myVariable), and PascalCase capitalises the first word too (MyVariable).
- Is my text sent to a server?
- No. Conversion runs entirely in your browser, so your text stays private and works offline.
