Case Converter

Convert text between UPPERCASE, lowercase, and Title Case instantly. Useful for headings, code, or normalizing pasted text.

About this tool

Case conversion changes the capitalization of letters in your text. UPPERCASE makes every letter capital; lowercase makes every letter small; Title Case capitalizes the first letter of each word. This is useful when you've copied text from a source that uses the wrong style, or when preparing headings, labels, or code constants.

How to use

Paste or type your text in the box above.
Click UPPERCASE to convert everything to capital letters.
Click lowercase to convert everything to small letters.
Click Title Case to capitalize the first letter of each word.

When to use this tool

Fixing headings or titles that are in the wrong case.
Preparing text for code (e.g. constants in UPPERCASE, keys in camelCase).
Normalizing pasted content from emails or documents.
Creating labels or buttons with consistent capitalization.

Tips

Title Case here capitalizes the first letter of each word; for complex rules (e.g. leaving small words lowercase) you may need to edit manually.
If you need Sentence case (only first letter of the sentence), use lowercase then capitalize the first character yourself.
