Convert text to UPPERCASE, lowercase, Title Case, Sentence case, and more, plus camelCase, snake_case, and kebab-case, in your browser.
UPPERCASE, lowercase, Title Case, Sentence case, Capitalize Each Word, and tOGGLE cASE.
camelCase, PascalCase, snake_case, and kebab-case, converted line by line.
Uses standard Unicode casing, so accented and Greek letters convert correctly. Scripts without case are left alone.
Spacing, punctuation, and line breaks are kept in the text cases.
When you use Case Converter, your data never leaves your browser. All transformations execute in-memory on your local machine with zero server uploads. Web assets are downloaded to run the tool, but your input data is never transmitted.
No. The conversion runs in your browser. Nothing is uploaded or stored. The page does download the code needed to run the tool.
Title Case capitalizes the first letter of each word and lower-cases the rest, so "mcDONALD" becomes "Mcdonald". Capitalize Each Word only raises the first letter and leaves the others as typed. Neither applies grammar rules for small words.
Everything is lower-cased, then the first letter of the text and of each sentence (after . ! ? or similar) is capitalized. Names and the word "I" are not recognised, so check the result.
It follows the standard Unicode mappings, which are right for most uses, but it is not locale-specific (for example, Turkish dotted and dotless i) and is not a claim of perfect casing in every language.
Count words, characters, lines, paragraphs, and reading time as you type. Works with English, Arabic, Greek, and more, right in your browser.
Remove repeated lines from a list while keeping the first occurrence of each, with case and whitespace options, in your browser.
Choose a case to convert the text. Title Case capitalizes each word and lower-cases the rest; Capitalize Each Word only raises the first letter. Sentence case lower-cases everything and capitalizes the start of each sentence (names and the word I are not recognised). Programming cases work line by line and treat punctuation as separators. Casing follows standard Unicode rules, not those of any one language. Press Ctrl+Enter (Cmd+Enter on Mac) in the input to repeat the last conversion. Processed locally in your browser.
