About this tool
Switch text between Title Case, UPPERCASE, lowercase, and slug-case in one place. The slug mode strips punctuation and joins words with hyphens, making it a quick way to turn headlines into URL-friendly strings.
How to use
- Enter your text in the Text field.
- Pick Title case, UPPERCASE, lowercase, or slug-case in the Mode dropdown.
- Copy the converted result.
Frequently asked questions
How does Title case decide what to capitalize?
It capitalizes the first letter of every word. It does not apply editorial style rules, so small words like "and" or "of" are capitalized too; adjust those manually if your style guide requires it.
What does slug-case produce?
Lowercase text with every run of non-alphanumeric characters replaced by a single hyphen and edge hyphens removed, e.g. "Hello, World!" becomes hello-world. Ideal for URLs and file names.
Does slug mode handle accented or non-Latin characters?
Characters outside a-z and 0-9 are replaced with hyphens rather than transliterated, so "café" becomes caf-. Transliterate accented text first if you need it preserved.
Is camelCase or snake_case supported?
Not currently. The four modes are title, upper, lower, and slug. For snake_case you can slug the text and replace hyphens with underscores.
Is my text processed locally?
Yes. Conversion is plain string manipulation in your browser; nothing is transmitted.
