A few useful details.
How do I change uppercase text to lowercase?
Paste or type in Original text. Lowercase is selected by default. The converted text appears instantly on the right, ready to copy or download.
What is the difference between title case and sentence case?
Title case capitalizes the first letter of every word. Sentence case capitalizes the first letter at the start of a sentence or line. These are automatic transformations; review names, abbreviations and acronyms yourself.
Can I convert non-English text?
Letters with Unicode case mappings are supported, including many accented letters. Scripts without uppercase and lowercase stay unchanged. Language-specific rules such as Turkish dotted and dotless I may require manual review.
Is my text stored or sent anywhere?
No. Conversion and file imports happen in this browser. The tool does not upload or save your document.
