Case Converter FAQs

Simple answers about changing letter case.

How do I convert uppercase to lowercase?

Paste your text into the box and click lowercase. Every capital letter turns into a small letter in one step, which makes this the easiest way to fix all caps to lowercase. It works the same as any uppercase to lowercase converter, with no download.

How do I change lowercase to upper case?

Paste the text and click UPPERCASE. The tool changes small case to uppercase instantly, so you can convert to capital letters for headings, labels or codes without retyping. It's a simple upper case converter that works on any device.

What is sentence case?

Sentence case capitalizes only the first word of each sentence, plus any names, like a normal paragraph. Example: "the meeting starts at noon. bring your laptop." becomes "The meeting starts at noon. Bring your laptop." Check proper nouns afterwards, because the tool can't know which words are names.

What's the difference between Capitalized Case and Title Case?

Capitalized Case capitalizes every word, including short ones like "and", "of" and "the". Title case usually keeps those short words lowercase unless they start the title. If you need a title case converter or developer formats like camelCase, open our Text Case Converter.

How do I change case in Microsoft Word or Google Docs?

In Word, select the text and press Shift + F3 to cycle through lowercase, UPPERCASE and Capitalize Each Word, or use the Change Case (Aa) button on the Home tab. In Google Docs, go to Format, then Text, then Capitalization. For text from anywhere else, paste it here.

How do I fix text typed with Caps Lock on?

Paste it into the case converter and click Sentence case. It changes capital to lowercase and restores capitals at the start of each sentence, so you don't have to retype anything. Then check names and brands.

Will it change numbers, symbols or spacing?

No. Only letters change. Numbers, punctuation, line breaks and spaces stay exactly as you pasted them, so lists, addresses and code snippets keep their layout.

Is this caps converter free on phones too?

Yes. The tool is free, needs no signup and works in any mobile browser. Use it as a lower case converter, an uppercase converter or a lowercase converter whenever you need to convert to lowercase or lower to upper case on the go.
