Convert text to upper case, lower case, title case and more
Paste your text, click the case you need and copy the result. It is the fastest way to fix text typed with Caps Lock on, clean up headings for a blog post or prepare consistent product names for a WooCommerce import.
How to use the case converter
Three steps, no sign-up and nothing is uploaded: the conversion happens in your browser. Besides the four case styles you can also turn text into Unicode bold, strikethrough or underlined text for social media bios, and remove repeated spaces.
Which text case should you use?
| Case | Example | Typical use |
|---|---|---|
| Title Case | How to Add Code to the WordPress Header | Book and article titles, some style guides for headings |
| UPPERCASE | SAVE 20% TODAY | Short labels, buttons, banners (avoid for long text) |
| lowercase | wordpress hooks | Tags, URL slugs, normalising data before comparing it |
| Capitalized Case | Every Word Starts With A Capital | Names and short display labels |
Case conversion for developers
Developers often need the same phrase in other formats too: camelCase for JavaScript variables, snake_case for PHP array keys and database columns, and kebab-case for CSS classes and URL slugs. Convert the text to lower case here first, then replace the spaces. In WordPress you can do the same in code with sanitize_title() for slugs and sanitize_key() for option and meta keys.
Frequently asked questions
Does capitalisation affect SEO?
No. Search engines treat upper and lower case the same in titles and content. Choose the style that is easiest to read and use it consistently across the site.
Is my text stored anywhere?
No. The text never leaves your browser and is cleared when you reload the page.
