Convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case, kebab-case and more instantly.
Frequently Asked Questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word (great for headlines). Sentence case capitalises only the first letter of each sentence, like normal prose.
What are camelCase, snake_case, and kebab-case used for?
They are naming conventions in programming. camelCase and PascalCase are common for variables and classes, snake_case for Python and databases, and kebab-case for URLs, CSS classes, and file names.
Can I convert a whole paragraph or document?
Yes. Paste any length of text. Every format updates instantly and you can copy whichever one you need.
Is my text sent to a server?
No. All conversions run entirely in your browser, so it is safe to paste private or unpublished text.
How do I fix text I typed with Caps Lock on?
Paste it in and copy the "lowercase" or "Sentence case" result to instantly fix the accidental capitals.
Case Converter — Change the Capitalisation of Any Text
Retyping text just to change its capitalisation is a waste of time, and fixing an accidental Caps Lock paragraph by hand is worse. This case converter transforms any text into the case you need in a single step. Paste your text once and instantly see it in every common format, ready to copy with one click.
The tool supports the eight most useful conversions. UPPERCASE makes every letter capital, and lowercase makes every letter small — ideal for fixing text typed with Caps Lock on. Title Case capitalises the first letter of each word, which is perfect for headlines and titles. Sentence case capitalises only the first letter of each sentence, the natural style for body text. For developers there are the programming conventions: camelCase and PascalCase for variable and class names, snake_case for Python and database fields, and kebab-case for URLs, CSS classes, and file names.
Each result updates live as you type and shows next to its own copy button, so you never have to select text manually. A running word and character count helps when you are also working to a length limit. Because everything happens in your browser, you can safely paste sensitive or unpublished text — nothing is uploaded, logged, or stored.
Common uses include cleaning up text that was typed with Caps Lock, formatting headlines and titles consistently, converting a label or heading into a code-friendly identifier, preparing slugs for URLs, and tidying content copied from emails or PDFs that arrived in the wrong case.
