What is the Case Converter?
The Case Converter changes the capitalisation of any text with one click. Convert to UPPERCASE, lowercase or Title Case, or turn a sentence into a clean URL slug with lowercase words joined by hyphens. It saves you from retyping text that was entered with caps lock on or copied in the wrong style.
How to use the Case Converter
- Paste or type your text into the box.
- Click the button for the style you want: UPPER, lower, Title Case or slug.
- Check the converted text in the result box.
- Press Copy and paste it where you need it.
Benefits and use cases
- Writers and students fixing headings and titles.
- Bloggers and web developers creating SEO-friendly URL slugs.
- Office workers cleaning up lists and spreadsheets copied in mixed case.
- Social media users who want text in a consistent style.
Tips for best results
Title Case here capitalises every word, so small words such as of and the will also start with a capital, and you may want to fix them by hand for formal headings. Use the slug button for blog posts and product pages, then keep the slug short and descriptive. Convert text before you paste it into a spreadsheet or code to avoid case mismatches.
