Text Case Converter
What Does a Text Case Converter Do?
A text case converter instantly reformats text between UPPERCASE, lowercase, Title Case, and Sentence case — useful when you've pasted text in the wrong case (a heading typed in all caps, a name pasted in lowercase) and don't want to retype it by hand.
Paste your text, pick a case, and get the converted result instantly — entirely in your browser.

When Each Case Style Is Used
1. Title Case for headings
Most style guides capitalize major words in headlines and titles — "The Complete Guide to SEO," not "the complete guide to seo."
2. Sentence case for body copy and UI labels
Modern UI writing (buttons, error messages, form labels) increasingly favors sentence case over Title Case for a more natural, conversational feel.
3. Avoid ALL CAPS for long text
UPPERCASE is harder to read for anything longer than a short label or warning, and can come across as shouting — reserve it for emphasis, not paragraphs.
Frequently Asked Questions (FAQ)
Q: What's the difference between Title Case and Sentence case?
A: Title Case capitalizes most major words ("This Is Title Case"); Sentence case only capitalizes the first word and proper nouns ("This is sentence case").
Q: Does Title Case capitalize every word?
A: Typically not small connecting words like "a," "the," "of," and "and" — proper style-guide Title Case leaves those lowercase unless they start the sentence.
Q: Is my pasted text uploaded anywhere?
A: No — case conversion happens entirely in your browser using standard JavaScript string methods.
