About the Case Converter
This free case converter changes the capitalization of your text in one click. Switch between UPPERCASE, lowercase, Title Case, Sentence case and more, then copy the result. It's a quick fix for headings pasted in the wrong case, all-caps text that needs toning down, or names and titles that need consistent capitalization.
Developers can also convert to camelCase, snake_case and kebab-case for variable names, database fields and URL slugs. Everything happens in your browser, so the conversion is instant and your text never leaves your device.
Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every major word, like a headline ("The Quick Brown Fox"). Sentence case only capitalizes the first letter of each sentence ("The quick brown fox").
Can I convert text to camelCase or snake_case?
Yes. The case converter includes developer-friendly formats — camelCase, snake_case and kebab-case — which are useful for variable names, file names and slugs.
Will it keep my line breaks?
Yes. Converting case never reflows or deletes your text; line breaks and spacing are preserved so you can paste the result straight back.
Is there a limit on how much text I can convert?
There is no fixed limit. Everything is processed locally in your browser, so you can convert anything from a single word to a long document instantly and privately.
