Upper and lower case follow this language, for example the Turkish dotted İ. Code cases and slugs stay language neutral.
Text case converter
Paste a heading, a list or a block of text and change its case in one click. Title Case knows the small words of English, Dutch, German, French, Spanish, Italian and more, keeps acronyms such as NASA and names such as iPhone, and upper and lower case follow your language, including the Turkish dotted İ. Developers get camelCase, snake_case and friends, and the cleanup tools repair text copied from PDFs. Nothing is uploaded. Type or paste text, then click a button to convert it in place: UPPERCASE, lowercase, Title Case, Sentence case, code cases such as camelCase or snake_case, or a URL slug. The cleanup buttons trim spaces, fix broken lines and remove bullets or emojis. Undo reverts every step and your text is saved in this browser.
How it works
- Type or paste your text in the large text box, or start with the sample text.
- Click a conversion such as Title Case, snake_case or URL slug, or a cleanup tool such as Fix broken lines. The text changes in place and the counts update live.
- Pick the language rules and the Title Case style if needed, undo any step, then copy the result or download it as a text file.
Case that respects language
Upper and lower case are not the same everywhere. In Turkish and Azerbaijani a lowercase i becomes a dotted İ and a capital I becomes a dotless ı, the German ß becomes SS, and in Dutch the IJ at the start of a word is capitalised as one letter. Choose the language rules or let the page language decide.
Clean text from anywhere
Text copied from a PDF, an email or a chat often has broken lines, double spaces, stray bullets and emojis. Fix broken lines joins the lines of a paragraph and repairs words split by a hyphen, while blank lines between paragraphs stay. Every step can be undone, and your text stays in this browser.
