Case Converter
Convert text to upper, lower, title, sentence, camel, Pascal, snake, kebab or constant case.
How to use this tool
- Paste or type your text into the box above.
- The result updates as you change the input — there is nothing to submit and nothing to wait for.
- Read the figures in the result panel, or copy the converted text.
- Use Copy or Download if you need the output elsewhere. Nothing was uploaded at any point.
Title case uses the standard convention of leaving short articles, conjunctions and prepositions lowercase unless they begin the string. All nine forms are produced at once, so you can copy whichever you need.
Case Converter — the specification

How it works
This tool runs entirely in your browser. There is no server involved, which means nothing you type or upload is transmitted, stored, or logged — and there are no usage limits, because there is nothing for us to ration.
You can confirm it yourself: open your browser's developer tools, select the Network tab, and use the tool. No request is made.

Everything above happened in the page as the text was typed. Nothing was sent to a server, which is why it works offline once the page has loaded and why there is no limit on how often you use it.
Who needs Case Converter
Writers fixing headline capitalisation, and developers converting names between the conventions different languages use.
Case Converter — frequently asked questions
What is the difference between title case and sentence case?
Title case capitalises most words — "How to Compress an Image". Sentence case capitalises only the first word and proper nouns — "How to compress an image".
Which case should I use in code?
Convention follows the language: camelCase for JavaScript and Java variables, snake_case for Python and Ruby, PascalCase for classes and types, kebab-case for URLs and CSS, CONSTANT_CASE for constants.
Does it handle accented characters?
Yes for upper, lower, title and sentence case. The programming cases strip non-alphanumeric characters, accents included, since identifiers rarely permit them.
Does this work offline?
Yes. Once the page has loaded you can disconnect from the internet and it keeps working, because all the processing happens in your browser. That is also the simplest way to confirm nothing is being sent anywhere.
Is there a limit on how much I can paste in?
Nothing we impose. The practical limit is your device’s memory, since the work happens locally. Very large inputs get slower rather than being refused.
Can I use this on a phone?
Yes. The layout adapts to a small screen and everything works the same way.
