About the Text Case Converter
A free online case converter built for writers, developers, and anyone working with text formatting.
What it is
The Text Case Converter instantly reformats any text into the case you choose — the moment you click a button. Paste your text, select one of eight case formats, and the converted result appears immediately, ready to copy with one click.
Everything runs in your browser. Your text is never sent to a server, stored, or logged anywhere. Close the tab and it's gone.
The eight supported cases
UPPERCASE
Converts every letter to capitals. Useful for headings, acronyms, and emphasis.
lowercase
Converts every letter to lowercase. Great for fixing accidental caps lock or normalising text.
Title Case
Capitalises the first letter of every word. Standard for article titles, headings, and names.
Sentence case
Capitalises the first letter of each sentence. Ideal for correcting improperly cased paragraphs.
camelCase
First word lowercase, subsequent words capitalised, no spaces. Common in JavaScript and JSON.
PascalCase
Every word capitalised, no spaces. Standard for class names in most programming languages.
snake_case
All lowercase with underscores between words. Widely used in Python, databases, and file names.
kebab-case
All lowercase with hyphens between words. Standard for URLs, CSS class names, and HTML attributes.
