About Case Converter

Convert text to every case at once: UPPER, lower, Title Case, Sentence case, camelCase, snake_case, kebab-case and more, each with its own Copy button. It can also reverse text, reverse the order of words, and turn text upside down. Your original text stays in the box, so nothing is lost, and everything runs in your browser.

How to Use

Add your text

Type or paste into the "Your text" box, or click Example.

Pick a version

Every case and the reversed versions appear below as you type. Click the copy icon on the one you need.

Keep converting (optional)

The arrow icon replaces your text with that version, so you can combine steps or open it in another tool with Send to. Undo brings back the previous text.

Text is converted in your browser and never uploaded.

Rules & Limitations

Code cases (camelCase, snake_case, kebab-case…) convert each line on its own, drop punctuation and remove apostrophes, so "don't stop" becomes "dontStop".
Title Case keeps short words such as "a", "of" and "the" in lower case and leaves acronyms like NASA and words like iPhone unchanged.
Sentence case cannot recognise names: it keeps "I", acronyms and words with capitals inside, and lowers everything else.
Hindi and other scripts without capital letters stay as they are; reversing keeps each Hindi syllable and emoji whole.

Case Converter FAQ

How do I change uppercase text to lowercase?

Paste the text into the box and copy the "lower case" version. To keep capitals at the start of sentences, copy "Sentence case" instead.

What is the difference between Title Case and Capitalize Each Word?

Capitalize Each Word gives every word a capital letter. Title Case follows headline style: short words such as "a", "and", "of" and "the" stay lower case unless they start or end the title, and acronyms like NASA are kept.

How do I reverse text?

Type or paste your text and copy "Reverse text" to get it backwards. "Reverse words" keeps each word readable but reverses their order on each line, and "Upside down" flips the letters so the text reads correctly when turned over.

What are camelCase, snake_case and kebab-case?

Ways of joining words without spaces, used in code and file names. camelCase gives "myVariableName", snake_case gives "my_variable_name", and kebab-case gives "my-variable-name", which is common in URLs and CSS classes.

Can I convert several names at once?

Yes. Put one name per line: the code cases convert each line separately, so a list of column names becomes a list of camelCase or snake_case names.

Is my text sent anywhere?

No. All conversions run in your browser. The text is not saved and is gone when you close or reload the page.
