Automatically capitalize the first word in your sentences. Convert text to sentence case, title case, uppercase, and more.
A sentence capitalizer is a text formatting tool that converts your text into the correct capitalization style with one click. It supports multiple styles including sentence case, title case, uppercase, lowercase, and inverse case. Instead of manually editing capitalization character by character, you paste your text and instantly get a properly formatted result. This is especially useful for fixing text that was accidentally typed in caps lock or converting between styles for different publishing contexts.
Proper capitalization is a sign of professional writing. Whether you are formatting headlines for a blog, cleaning up email subject lines, or preparing product names for a catalog, consistent capitalization improves readability and credibility. After capitalizing your text, check it with our Grammar Checker for a complete polish, or use the Text Formatter for additional transformations like removing duplicates or trimming spaces.
Capitalization rules are fundamental to professional writing and SEO. Search engines display your meta titles and descriptions exactly as written, so inconsistent capitalization makes your search listings look unprofessional and reduces click-through rates. Title case headlines in blog posts are perceived as more authoritative, while sentence case works better for social media and email subject lines. Use our Meta Tag Generator to build properly capitalized meta tags, and check your content length with the Character Counter to stay within platform limits.
Sentence case capitalizes only the first letter of each sentence ('The quick brown fox'), while title case capitalizes the first letter of major words ('The Quick Brown Fox'). Use sentence case for body text and title case for headings.
In title case, minor words like articles (a, an, the), short prepositions (at, by, for, in, of, on, to), and coordinating conjunctions (and, but, or, nor) are typically not capitalized unless they start the title.
Use uppercase sparingly for acronyms (NASA, FAQ), strong emphasis, legal document headings, or stylistic purposes. Avoid using all caps for body text as it reduces readability and can appear like shouting.
Paste your ALL CAPS text into our tool and click 'Sentence case' or 'lowercase' to convert it. Sentence case will properly capitalize just the first letter of each sentence while making everything else lowercase.
Inverse case swaps the capitalization of each character - uppercase becomes lowercase and vice versa. It's primarily used for creative or stylistic purposes, fixing accidental caps lock, or creating unique text effects.
