Convert between cases.
Retyping text to change its case is error-prone and slow. Paste it here instead and switch between uppercase, lowercase, title case, sentence case and the programming styles camelCase, PascalCase, snake_case and kebab-case in one click.
Uppercase and lowercase change every letter. Title case capitalises each significant word, while sentence case capitalises only the first word. camelCase, PascalCase, snake_case and kebab-case are the identifier styles used in code, config keys, URLs and CSS class names.
Headings, article titles and labels usually read best in title or sentence case. Sentence case is calmer and more modern for long headings; title case is conventional for navigation and proper titles. Either way, converting is faster than fixing each word by hand.
camelCase is standard for JavaScript variables and methods. PascalCase is used for class names and React components. snake_case is common in Python, SQL and environment variables. kebab-case is used in URLs, CSS classes and HTML attributes.
The converter normalises the text before applying the target style, so mixed input such as an ALL CAPS label or a sentence with random capitals comes out consistent. Words are split on spaces and common separators so multi-word phrases convert correctly.
Text is sent only to be converted and is not stored or shown to anyone else. There is no account and no history, so pasting drafts, code snippets or internal labels is safe within the normal limits of a web form.
Paste the text and choose the uppercase option. The whole input is converted at once.
Title case capitalises the significant words in a heading. Sentence case capitalises only the first word and leaves the rest lowercase except for proper nouns.
Yes. Choose camelCase and multi-word phrases become identifiers such as myVariableName.
Yes. Both are available, along with PascalCase, which is useful for class and component names.
No. The text is converted and returned; it is not stored as history or attached to an account.
Yes, within the form limits. For very large documents, convert the section you are working on rather than the whole file.
