What is the Case Converter?
The Case Converter is a free online tool that instantly changes the capitalization of your text. Choose from six styles: UPPERCASE, lowercase, Title Case, Sentence case, aLtErNaTiNg, and iNVERSE cAsE. It is perfect for fixing text typed with caps lock on, formatting headings, or creating stylized social media text — all in one click, right in your browser.
How to use it
- Paste or type your text into the box.
- Click one of the six style buttons to convert the text in place.
- Click a different style any time to convert again from the current text.
- Use “Copy result” to copy the converted text, or “Clear” to start over.
Key features
- Six conversion styles, including alternating and inverse case for playful text.
- Smart Title Case that capitalizes after spaces, hyphens, and brackets.
- Sentence case that lowercases everything, then capitalizes each new sentence.
- Live character count that updates as you type or convert.
- One-click copy and clear buttons; no sign-up, fully private.
Real-world use cases
Writers fix entire paragraphs accidentally typed in caps lock. Bloggers format headings in Title Case without retyping. Developers convert labels to lowercase for slugs or filenames. Social media users create alternating-case text for memes and playful posts.
Practical tips
- Use Title Case for headings and Sentence case for body text — mixing them looks unprofessional.
- UPPERCASE reads as shouting online; reserve it for short labels and warnings.
- Convert to lowercase first if your source text has random capitalization, then apply Title Case for the cleanest result.
Frequently Asked Questions
What does the inverse case button do?
It swaps the case of every letter: uppercase becomes lowercase and lowercase becomes uppercase. Numbers and punctuation are left unchanged.
How does alternating case work?
It alternates lowercase and uppercase across the letters in your text, skipping numbers, spaces, and punctuation so the pattern stays clean.
Will Title Case handle hyphenated words?
Yes. Words after hyphens, dashes, spaces, and opening brackets are capitalized, so “well-known” becomes “Well-Known”.
Can I undo a conversion?
Converting again from the result works for most styles, but alternating and inverse are lossy. For important text, copy the original before converting.
Is my text uploaded anywhere?
No. Conversion happens entirely in your browser and your text is never sent to a server.
