Case Converter

Convert text casing instantly.

Paste text and switch it between common writing and code-friendly case formats without uploading it.

Converted text will appear here.

How it works

The converter reads the pasted text in the page, normalizes word boundaries where needed, and applies the selected casing, identifier, or URL slug format directly in the browser.

All conversions happen immediately in the page.

Practical examples

  • Turn a rough heading into title case, sentence case, or uppercase variants.
  • Convert labels into camelCase, kebab-case, snake_case, or URL slugs for filenames, IDs, and links.
  • Normalize inconsistent capitalization copied from documents or spreadsheets.

How to read the result

  • Word-boundary formats rebuild the text from detected words.
  • Sentence case keeps punctuation-driven sentence starts readable.
  • URL slug mode removes accents, lowercases text, and keeps clean hyphen separators.

Limits and privacy notes

  • Language-specific title-case rules are not exhaustive.
  • Acronyms and brand capitalization may need manual review.
  • Conversion runs locally in your browser; pasted text is not uploaded.

Manual review

Brands and acronyms

  • Automated casing cannot know every brand style.
  • Review acronyms after title or sentence case conversion.
  • Slug mode strips accents for safer URLs.

Clean text before publishing

  • Use Character Counter after conversion for length limits.
  • Use Base64 only for encoding payload snippets.
  • Use JSON Formatter for structured data, not prose.

Frequently asked questions

Will title case preserve brand names and acronyms?

Not reliably. Automatic casing cannot know every house style, so review brands and acronyms after conversion.

What does URL slug mode do with accents?

It normalizes accented letters where possible, lowercases the result, removes unsupported characters, and joins words with hyphens.

How do identifier formats handle punctuation?

camelCase, kebab-case, and snake_case rebuild the value from detected letter and number groups rather than preserving punctuation.

Is converted text uploaded?

No. The transformations run in the current browser tab.
