Writing Utility
Case Converter
Convert text to uppercase, lowercase, simple title case, or simple sentence case directly in your browser.
Convert text case
Choose a conversion.
How the modes work
- UPPERCASE: uses the browser’s uppercase transformation.
- lowercase: uses the browser’s lowercase transformation.
- Title Case: lowercases each space-separated word and capitalizes its first character, line by line.
- Sentence case: lowercases the text and capitalizes the first character of each line. It is intentionally simple.
Limitations
Capitalization is language- and context-sensitive. The simple Title Case and sentence-case modes are not grammar-aware. Proper nouns, acronyms, brand names, abbreviations, and language-specific casing rules may need manual correction.
Privacy
The input and output text remain in the browser.
Common questions
Will Title Case follow a specific publishing style?
No. This is a mechanical capitalization tool, not APA, MLA, Chicago, AP, or another editorial title-capitalization standard.
Does the converter preserve line breaks?
Yes. The title and sentence modes process lines separately.
