How to use this case converter
Convert text between UPPER CASE, lower case, Title Case, Sentence case, Capitalized Words and aLtErNaTiNg cAsE. Type or paste your text into the box, pick a case style, and the converted result appears instantly with no button to press and no signup.
How to use it: paste your headline, paragraph or list, click one of the six case buttons (Title Case is the default), then copy the result with “Copy result” or clear the box to start over. The slug preview below turns the same text into a clean URL-friendly slug you can copy for headlines and file names.
Styles explained: UPPER CASE capitalizes every letter; lower case makes everything lowercase; Title Case and Capitalized Words capitalize the first letter of each word; Sentence case capitalizes the first letter of each sentence; aLtErNaTiNg cAsE alternates upper and lower per letter for stylized text.
Privacy: everything runs in your browser — nothing you type is uploaded, stored or logged. Clearing the box removes it from the page immediately.
FAQs
Is the case converter free?
Yes. It is free with no signup, no account and no usage limits.
Is my text uploaded or stored anywhere?
No. Conversion happens entirely in your browser. Nothing you type leaves your device, and nothing is sent to a server or stored in the CMS.
Which case styles are supported?
UPPER CASE, lower case, Title Case, Sentence case, Capitalized Words and aLtErNaTiNg cAsE — six styles covering headings, sentences and stylized text.
What is the difference between Title Case and Capitalized Words?
Both capitalize the first letter of each word the same way in this tool; pick either one for headlines and headings.
How does Sentence case work?
It lowercases the text first, then capitalizes the first letter of the text and the first letter after each sentence-ending mark (. ! ? …).
What is the slugified output for?
It turns your text into a lowercase URL-friendly slug (words joined with hyphens, special characters removed) that you can copy for headlines, file names and links.
Is there a text length limit?
No fixed limit. Very large pastes are still processed locally, though extremely long documents may feel slower depending on your device and browser.
Does it work on mobile?
Yes. The tool is mobile-first with a single-column layout, large tap targets and no horizontal scrolling.
