Overview

Onlineconvertercase changes pasted text into the case you need. It can also reverse text, remove spaces, line breaks or HTML tags, and convert a selected section without changing the rest. Onlineconvertercase processes your text in your browser, so it is not uploaded or stored. Most converters change only letter case and keep your original wording intact.

Key Features

One-click conversion
Our online case converter tool fixes this in one click.
Browser processing
Your text is processed entirely in your browser.
Partial conversion
You can also select just a part of your text and convert only that part, leaving the rest unchanged.
Accented letters
Every letter of the alphabet is supported, including accented letters like é and ñ.
Lower case
Lower Case converts all your letters into small letters.
Upper case
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
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
Sentence Case capitalizes the very first letter of every sentence and makes the rest of the text lowercase.
Camel case
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
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
Remove Spaces, also known as "space deleter", removes all the spaces from your text.
Remove line breaks
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
Reverse Text flips your whole text backwards. The text you type will be flipped so its characters appear in reverse order.
Remove HTML tags
Remove HTML Tags keeps only the readable text and removes all the HTML code from your content.
Local processing
Your text is processed entirely in your browser.
Preserved wording
It is never uploaded or stored anywhere, and most of our converters only change letter case while leaving your words themselves exactly as you typed them.
Case conversion
You can transform your text into any case you need, instantly.
Toggle Case
Toggle Case swaps the case of every letter. It switches every uppercase letter to lowercase and every lowercase letter to uppercase.
Proper Case
Proper Case converts the first letter of every single word to a capital, while the other letters stay lower case.
Alternate Case
Alternate Case, also known as "SpongeBob case", switches every letter between lowercase and uppercase, starting with a lowercase letter.
Random Case
Random Case converts your letters randomly into a mix of uppercase and lowercase, with no fixed pattern. Each click gives a different result.
