Convert Text Case Online — UPPER, Title, camelCase & More

A headline arrived in all caps from a partner. A CSS class needs kebab-case. A constant in code wants CONSTANT_CASE. Rewriting by hand invites typos — especially on long strings.

Case Converter applies the style you pick to the whole paste:

• UPPER / lower
• Title Case / Sentence case
• camelCase / PascalCase
• snake_case / kebab-case / CONSTANT_CASE / dot.case

Word boundaries follow Unicode letter/number tokens, so mixed-language titles convert more sanely than naive ASCII-only tools.

Quick examples

Steps

1. Open Case Converter.
2. Paste the string or paragraph.
3. Choose the target style.
4. Copy the result.

For URL-ready titles, Slug Generator goes further (accents stripped, separators normalized). For one-off string swaps that aren’t about case, use Find and Replace.

FAQ

Will Sentence case fix every abbreviation?

It capitalizes after .!?… heuristics. Abbreviations like Dr. can still confuse sentence detection — skim the output.
