About the Case Converter

You left Caps Lock on for a paragraph, or you pasted a headline that arrived in ALL CAPS, or a client sent a product list where every word is capitalised except the ones that matter. Retyping it is ten minutes you will not get back, and your keyboard has no 'make this Title Case' key. This tool takes the text as it is and hands it back in the casing you actually wanted. Nine options, applied the moment you pick one, with the character and word count updating as you type. Everything happens inside this tab — the text never leaves your browser, so a draft you have not published yet stays exactly as private as it was in your clipboard.

How to use it

  1. 1Paste your text into the first box — a word, a paragraph, or a whole list of lines.
  2. 2Pick a casing. The result appears straight away; switch between casings as many times as you like without pasting again.
  3. 3Hit Copy result. Or use it as input to stack another conversion on top, like UPPER first and then Title Case.

Why use it

Casings that behave
Title Case keeps small words like 'of' and 'the' lowercase in the middle of a headline, and Sentence case capitalises after every full stop — not just the first letter of the whole block.
Your accents survive
Text is handled as real characters, not bytes, so 'café' and 'Zoë' come back correct in every mode — including the alternating and inverse ones that flip letter by letter.
Counts while you work
Characters, words, sentences and lines, live. Handy when a field caps you at 160 characters and you are trimming to fit.
Nothing uploaded, nothing metered
No account, no daily limit, no request to a server. Paste an unpublished draft or an internal list without thinking twice.

FAQ

What is the difference between Title Case and Capitalized?

Capitalized capitalises every single word: 'The Art Of War'. Title Case follows the convention used for headlines and keeps short joining words lowercase unless they start or end the line: 'The Art of War'. If you are writing a headline, Title Case is the one you want.

Does Sentence case handle more than one sentence?

Yes. It lowercases everything, then capitalises the first letter of each sentence — after a full stop, question mark or exclamation mark, and at the start of each new line. Paste three paragraphs and all of them come out right.

What are snake_case and kebab-case for?

They turn a phrase into a single machine-safe token: 'Hello World' becomes hello_world or hello-world. Developers use snake_case for variable names and database columns, and kebab-case for URLs, CSS classes and file names. Punctuation is dropped and runs of spaces collapse into one separator.

Is there a limit on how much text I can paste?

No hard limit. The work happens in your browser, so the only ceiling is your device's memory. Tens of thousands of words are fine; a whole book pasted at once will feel sluggish while it converts.

Do you store or read what I paste?

No. There is no upload step at all. Open your browser's network tab and convert something — you will see no request, because the conversion is a few lines of JavaScript running on your machine.

Why did my ALL CAPS acronym get lowercased?

Most modes lowercase the text first and then apply their rule, so 'NASA' becomes 'Nasa' in Title Case. That is standard behaviour for a case converter, but it does mean acronyms need fixing by hand afterwards. If you only want the first letter of the block changed, use Sentence case and then repair the acronym.
