  • Title Case — Blog headings, article titles, H1/H2 tags
  • Sentence case — Body text, captions, subtitles
  • UPPERCASE — CTA buttons, banners, labels
  • lowercase — Tags, categories, URL components

Developer Naming

  • Capitalize: nouns, verbs, adjectives, adverbs
  • Lowercase: a an the (articles)

Frequently Asked Questions

What is a case converter?
A case converter is a tool that changes the capitalization style of text. You paste your text, select a format — UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, PascalCase, or kebab-case — and the tool converts it instantly. No manual editing needed.
How do I convert uppercase to lowercase online?
Paste your UPPERCASE text into the input area, tick the security check, then click the lowercase button. The text is instantly converted to all lowercase and shown in the result panel. Click Copy Result to copy it to your clipboard.
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of each major word — like a book title or article heading (The Quick Brown Fox Jumps). Sentence case only capitalizes the first letter of the first word in a sentence, like normal writing (The quick brown fox jumps). Most blog headings use Title Case; body text and subtitles use Sentence case.
What is camelCase and when should I use it?
camelCase joins words without spaces, capitalizing each new word after the first: myVariableName. It is the standard naming convention in JavaScript and Java for variables and functions. The FindBeam converter splits on spaces and capitalizes accordingly.
What is the difference between snake_case, PascalCase, and kebab-case?
snake_case uses underscores between lowercase words (my_variable_name) — the Python PEP 8 standard and common in SQL. PascalCase capitalizes every word including the first (MyClassName) — used for class names in most languages and React components. kebab-case uses hyphens between lowercase words (my-component-name) — the standard for CSS class names, HTML attributes, URL slugs, and npm package names.
Is my text private when using this converter?
Yes, completely. All case conversion happens entirely in your browser using JavaScript. No text is ever sent to FindBeam's servers or any third party. You can verify this by switching to airplane mode — the converter still works.
What are the Title Case rules for articles and prepositions?
In standard Title Case, short articles (a, an, the), coordinating conjunctions (and, but, or, nor), and short prepositions (on, at, to, from, by) are kept lowercase unless they are the first word. FindBeam applies these rules automatically.
Is this case converter free?
Yes. FindBeam's Case Converter is completely free with no account, no registration, and no usage limits. It will remain free.
