Our online case converter tool fixes this in one click.
Your text is processed entirely in your browser.
You can also select just a part of your text and convert only that part, leaving the rest unchanged.
Every letter of the alphabet is supported, including accented letters like é and ñ.
Lower Case converts all your letters into small letters.
Upper Case converts all of your letters to capital letters. E.g. "good morning" becomes "GOOD MORNING". Just paste your text into the box and click the UPPERCASE button.
Title Case capitalizes the first letter of every important word, while common small words like "a", "an", "the", "of", "in", "on", "and", and "or" stay lowercase (unless they are the first or last word).
Sentence Case capitalizes the very first letter of every sentence and makes the rest of the text lowercase.
Camel Case, also known as lower camel case, keeps the first word in lowercase and starts every following word with a capital letter, removing the spaces.
Snake Case replaces all the spaces with an underscore ( _ ) and writes every letter in lower case. It is mostly used for programming and function names.
Remove Spaces, also known as "space deleter", removes all the spaces from your text.
Remove Enter removes all the line breaks created by the Enter key and turns your text into a single paragraph without new lines.
Reverse Text flips your whole text backwards. The text you type will be flipped so its characters appear in reverse order.
Remove HTML Tags keeps only the readable text and removes all the HTML code from your content.
Your text is processed entirely in your browser.
