Case Converter: Uppercase, Lowercase, Title Case, and More

Example This is an example of sentence case.

What this case converter does

It takes whatever you typed — a headline, an email, a product title, a paragraph that got stuck in caps — and rewrites the letters. Words stay in the same order. Punctuation stays put. You choose the format with the buttons under the box.

Formats on this page

Sentence case capitalizes the first letter after a full stop and turns a lone “i” into “I.” Lower case uncapitalizes everything. UPPER CASE shouts on purpose. Capitalized Case starts every word with a capital. Alternating case flips letter by letter. Title case follows common headline rules. Inverse case swaps whatever is already there.

Writing jobs it is actually for

Use it when a title tag is in the wrong case, when a spreadsheet dumped names in caps, or when you want a headline to look like a title before you paste it into the CMS. It will not invent names or place names in sentence case. That still takes a person.

Settings

Turn on convert-as-you-type if you want the next keystroke to keep the last format. Title-case settings can leave small words lowercase. Sentence case can force a standalone “i” to “I.” Those choices stay in this browser until you change them.

Uppercase converter, lowercase converter, and case changer — one page

People search those phrases separately. They are the same job: take text you already have and change how the letters look. This URL is the canonical tool. Case changer, uppercase converter, and lowercase converter redirect here so Google is not asked to choose between twins.

If you are writing a title tag or an H1, convert first, then check length in the title and meta preview. If the draft is long, count it with the word counter. None of those widgets will tell you whether the page should exist. That decision is in the on-page SEO guide and how to use a case converter.

What each button is for

Sentence case is the usual fix after Caps Lock. The first letter of each sentence becomes a capital; the rest drop to lowercase; a lone “i” can become “I.” It will not capitalize a person’s name or a city. Read the result once.

lower case uncapitalizes everything. Use it on a spreadsheet dump or a shouty email you intend to rewrite, not on an acronym you still need (NASA will become nasa).

UPPER CASE is the uppercase converter. Use it for a short label, not for a paragraph you expect someone to read.

Capitalized Case starts every word with a capital. Title Case leaves small words such as “and” and “of” lowercase unless they open the title — closer to how an essay title is usually written. Alternating case and Inverse case are stylistic. They are not for a service page.

Copy, share, download

Copy puts the current box on the clipboard. Share offers this tool URL (not a 10,000-character query string). Download saves a .txt file. Clear empties the box. Settings remember whether you want live conversion, title-case small words, and the standalone “I” rule — in this browser only.

The character, word, and line counts update as you type. They are the same kind of check as the dedicated word counter: useful, not a ranking score.

FAQ

Does this case converter upload my text?

No. Conversion happens in your browser. Scriplit does not receive the draft unless you later paste it into a form on another page.

What is the difference between title case and capitalized case?

Capitalized case uppercases the first letter of every word. Title case leaves small words such as “and,” “of,” and “the” lowercase unless they start the title, which is closer to how essay titles are usually written.

Can I use this as an uppercase or lowercase converter?

Yes. The UPPER CASE and lower case buttons do that job. Searches for case changer, uppercase converter, and lowercase converter all belong on this same page — we do not publish lookalike URLs for each button.
