- Choose Turkish or German rules when the text needs them, then press Copy result.
Title Case or Capitalized Case?
Title Case capitalizes the first letter of each word but keeps short words such as a, an, and, of, on, the and to in lowercase, except at the start or end of a line and after a colon or a period. Capitalized Case capitalizes every word. Neither recognizes names, acronyms or abbreviations, so NASA becomes Nasa in both; fix those by hand.
English, Turkish, German and Greek case rules
English is the default, and English and German share the same letter mappings here. Turkish treats dotted and dotless I as different letters, so i becomes İ and I becomes ı. Uppercase changes ß to SS, and lowercase gives ss rather than the original ß. Greek gets its final-form sigma when a word ends in Σ. Accented letters, Cyrillic and Armenian convert with the same rules as plain Latin letters.

- How do I fix text typed with Caps Lock on?
- Paste it and choose Invert case. Capitals become lowercase and lowercase becomes capitals, so hELLO wORLD turns back into Hello World. If the whole text is in capitals, Sentence case or lowercase is faster.
- Does sentence case correct my writing?
- No. It follows simple rules, without recognizing names or abbreviations, fixing grammar, or applying title case. NASA becomes Nasa, and 1) BUY becomes 1) buy. Check names and abbreviations yourself.
- Which alphabets does it convert?
- Any script with upper and lower case: Latin letters with accents, Cyrillic, Greek and Armenian. Arabic, Hebrew, Chinese, Japanese, Korean, Thai and Devanagari have no letter case, so that text passes through unchanged.
- What stays unchanged?
- Numbers, punctuation, spacing, emoji and line breaks stay in place. Scripts without letter case are unchanged. Your original text remains available above.
- Is my text uploaded anywhere?
- No. The conversion runs in your browser and the text is not sent to a server. Usage counts record that the tool was used, never what you typed.
