Change the letter case of any text in one click – for writing, headings and programming.
What is the Case Converter?
Typed a whole paragraph with Caps Lock on? Need a proper headline or a variable name for your code? This case converter changes the capitalisation of any text instantly. It supports 12 styles: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, aLtErNaTiNg and iNVERSE case.
Title Case follows common headline rules and keeps small words such as "and", "of" and "the" in lowercase unless they start the title – great for blog titles and YouTube videos.
How to use the Case Converter
- Paste or type your text.
- Click the case style you want.
- Copy the converted text, or click "Use as input" to convert again.
Which case should I use?
| Style | Example | Best for |
|---|---|---|
| Title Case | How to Start a Blog | Headlines, titles |
| Sentence case | How to start a blog | Normal writing, UI text |
| camelCase | startBlogPost | JavaScript variables |
| snake_case | start_blog_post | Python, databases |
| kebab-case | start-blog-post | URLs, CSS classes |
| CONSTANT_CASE | MAX_POSTS | Constants, env variables |
Tips
- Use Sentence case for body text – writing in ALL CAPS feels like shouting.
- Use kebab-case for SEO-friendly URL slugs (or try our Slug Generator).
- Proper names may need a quick manual check after converting to lowercase or sentence case.
