Convert text to UPPERCASE, lowercase, Title Case, sentence case, and more.
Case Converter rewrites your text into a different letter case, switching between UPPERCASE, lowercase, Title Case, sentence case, and more with one click. The annoyance it removes is retyping. When someone sends a heading in all caps, or you paste a line that is stuck in the wrong case, fixing it letter by letter is slow and easy to get wrong, so a converter that reflows the whole block saves the fiddling.
You paste your text, choose the case you want, and the tool returns the reworked version ready to copy back out. Nothing is submitted anywhere. You can try one style, glance at the result, and switch to another if it is not quite right, which makes it easy to land on the exact look you need.
It helps to know what each mode does. UPPERCASE and lowercase are literal, changing every letter. Title Case capitalizes the start of each word, which is great for headings but will also capitalize small words a strict style guide might leave lowercase, so a headline may need a quick manual touch. Sentence case capitalizes the first letter after each sentence, and it relies on punctuation, so oddly punctuated text can throw off where a new sentence is judged to begin.
You could do some of this inside a word processor's format menu, but it is buried and often applies only to certain styles. This tool is quicker for a one-off block and works on plain text you are about to paste elsewhere, such as into a form or a code comment. When you want case changes baked into a document's styles rather than the raw text, your editor is the place for that.
People use it to tame an all-caps message, to format headlines and titles consistently, to fix a name or address that came in the wrong case, and to standardize labels or data before pasting them somewhere. Writers, editors, and anyone cleaning up copied text find it handy.
Everything happens in your browser, so your text is not uploaded, there is no sign-up, and it costs nothing. The only real limit is your device's memory, and since changing case is simple work, it handles a single line or a whole page without slowing down.
It capitalizes the first letter of each word, which matches the general idea of title case but not the finer rules that keep short words like and or of lowercase. For a strict style, you may need to lowercase a few small words yourself.
It looks for sentence-ending punctuation such as a full stop or question mark to decide where to capitalize next. Text with abbreviations or missing punctuation can occasionally start a new capital in the wrong spot.
Yes, converting case changes letters only and leaves your paragraph breaks and spacing in place. The structure of your text comes back the same, just in a different case.
Digits, punctuation, and symbols are left untouched, since case applies only to letters. A code or a phone number pastes back exactly as it went in.
Yes, picking any target mode rewrites the whole block from scratch, so a jumble of upper and lower letters comes out uniform. Choose the style you want and the previous mess is overwritten.
Accented letters convert case along with plain ones in most cases, following your browser's handling of those characters. Very unusual scripts may not have a separate upper and lower form, in which case they pass through unchanged.
No. The conversion happens in the page and nothing is uploaded or saved, so your text is gone once you close the tab. Copy the result out before leaving.
