Title Case vs Capitalize Each Word

Capitalize Each Word puts a capital at the start of every word. Title Case follows the style newspapers and books use: short words such as a, an, the, and, but, or, of, in, on, at, to stay lowercase unless they are the first or last word, or come right after a colon. So “the lord of the rings” becomes “The Lord of the Rings”. If you prefer every word capitalised, switch off “Keep small words lowercase”.

Smart about acronyms, “I” and Hindi

  • In Title, Sentence and Capitalize modes, acronyms like SSC, IBPS and PDF, and brand spellings like iPhone or YouTube, stay as you typed them. If the whole text is in capitals, everything is converted.
  • Sentence case capitalises “I” and the first word after a full stop, ! , ?, the Hindi danda (।) and line breaks — but not after “e.g.” or “i.e.”.
  • The tool can’t know which words are names, so after sentence or lower case, check proper nouns like Delhi or Monday.
  • Hindi and other Devanagari text has no capital letters, so it is left exactly as it is. Mixed Hindi–English text works fine.

Handy for forms and assignments

Some application forms ask for your name and address in capital (block) letters — convert it here and paste it in. Writing an essay or answer with a word limit? Check its length with the word counter. Working with Hindi typing fonts? Use the Unicode to Kruti Dev converter.

Frequently asked questions

How do I convert capital letters to small letters?

Paste your text in the box and tap “lower case”. Every capital letter becomes small, and you can copy the result or download it as a .txt file. To fix text typed with Caps Lock on, “Sentence case” is usually better, because it keeps capitals at the start of each sentence.

What is the difference between Title Case and Sentence case?

Title Case capitalises the main words of a heading, like “How to Prepare for the Exam”. Sentence case writes text the way normal sentences are written: only the first word of each sentence (and “I”) gets a capital, like “How to prepare for the exam”.

Does the case converter work with Hindi text?

Hindi has no upper or lower case, so Hindi words are left exactly as they are. In mixed Hindi–English text, only the English words change.

Will it change acronyms like SSC or names like iPhone?

In Title, Sentence and Capitalize modes, words written fully in capitals (SSC, PDF) or with a capital inside (iPhone, YouTube) are kept as typed. UPPER CASE, lower case, aLtErNaTiNg and InVeRsE always change every letter.
