UPPER, lower, Title, camel, snake…
Retyping a line because it is in the wrong case is pure waste, and shouting caps-lock text is the most common version of the problem. This converter shows the same text in eight formats at once — the four prose cases plus the four naming conventions programmers need — each with its own copy button, so you pick the one you want rather than converting and re-converting.
How to change text case
- 1
Paste your text
Drop in a word, a heading, or a whole paragraph.
- 2
Read every case at once
UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case are all generated live.
- 3
Copy the one you need
Each format has its own copy button, so there is no re-selecting.
Good to know
- Sentence case capitalises the first letter of the sentence; Title Case capitalises each significant word.
- camelCase and PascalCase suit variable and class names; snake_case suits Python and database columns; kebab-case suits URLs, CSS classes, and file names.
- Punctuation and line breaks are preserved, so a whole paragraph survives the conversion intact.
- Conversion runs in the page — nothing is uploaded or logged.
What people use it for
- Fixing a heading or product name that arrived in all caps
- Renaming a variable to match the conventions of a different language
- Turning a page title into a CSS class or file name
