Convert text between uppercase, lowercase, title case, sentence case and other common capitalization styles.
Input: plain text whose capitalization you want to change.
Output: the same text transformed to the selected case style.
How to use it
- Paste the text and choose the case style that matches your destination.

Privacy, accuracy and limits
Automated title/sentence case cannot know every proper noun, acronym or editorial style rule. Review names and branded terms manually.
WebToolMint keeps this workflow local in the browser where the feature allows it. Network-dependent tools are labelled separately. Keep originals and independently verify results that affect legal, financial, medical or business decisions.
Frequently asked questions
Does Title Case follow AP, Chicago or another style guide?
Generic title case is rule-based and may not match every editorial style. Review small words, acronyms and proper nouns.
Can I convert a large block of text?
Yes for ordinary text sizes, though very large input can make any browser editor less responsive.
Will punctuation be removed?
Case conversion should change letter casing rather than intentionally remove punctuation.
