Text Case Converter
Convert text between UPPERCASE, lowercase, Title Case, Sentence case, and other styles in one click. It saves the tedious manual retyping when text arrives in the wrong case.
Text Case Converter
Enter your text once and instantly generate multiple case variations with one-click copy.
The cases you actually need
Text often comes in the wrong case: a heading typed in all caps, a name in lowercase, a sentence shouting. Rather than retype it, you pick the target case and the tool rewrites it. The common styles are UPPERCASE, lowercase, Title Case (each major word capitalized), and Sentence case (first letter capitalized).
Title Case has a subtlety: strict style guides do not capitalize small words like 'and', 'of', or 'the' unless they start the title. Simple converters capitalize every word, so review headlines if you follow a specific style.
Where it helps
It is a small task that comes up constantly.
- Fixing headings and titles pasted from another source.
- Normalizing names or data that arrived in inconsistent case.
- Toning down text that was typed in all caps.

FAQs
What is the difference between Title Case and Sentence case?▼
Title Case capitalizes the first letter of each major word, used for headings. Sentence case capitalizes only the first letter of the sentence (and proper nouns), like normal prose.
Does Title Case follow style-guide rules for small words?▼
Basic conversion capitalizes every word. Strict styles (like AP or Chicago) leave short words such as 'and', 'of', and 'the' lowercase unless they begin the title, so review headlines manually.
Is my text sent to a server?▼
No. The conversion runs in your browser, so the text stays on your device.
Will it fix proper nouns in Sentence case?▼
It cannot reliably know which words are proper nouns, so names may need a manual capital after converting to Sentence or lowercase.
Can it handle accented or non-English letters?▼
Yes. Accented letters are uppercased and lowercased correctly for most languages, since it uses standard case mapping.
What does 'toggle case' do?▼
It flips the case of each letter, making uppercase lowercase and vice versa. It is mainly useful for fixing text typed with the caps lock accidentally on.
Does converting to UPPERCASE lose any information?▼
It loses the original capitalization, so you cannot perfectly reverse it back to mixed case automatically. Keep the original if you might need it.
Can I convert a large block of text at once?▼
Yes. Paste any amount and convert it in one action; there is no need to do it line by line.
Does it change punctuation or spacing?▼
No. It only changes letter case. Punctuation, numbers, and spacing are left exactly as they were.
