About the Text Case Converter
A text case converter changes capitalization without requiring you to retype content. It is useful for headings, labels, titles, interface strings, notes and copied text that uses inconsistent capitalization.
How to use this tool
Paste your text and choose the desired case. Uppercase and lowercase are direct transformations. Title Case capitalizes major words using a practical word-based rule, while Sentence case capitalizes the beginning of sentences. Review names, abbreviations and technical terms after conversion.
- Open the Text Case Converter page on Tervilo.
- Enter or paste the text you want to work with.
- Choose any options relevant to the task.
- Run the tool and review the result before copying or publishing it.
How the calculation or transformation works
Case conversion operates on Unicode characters supported by the browser. Title and sentence case are heuristic transformations rather than language-aware editorial proofreading, so proper nouns and acronyms may require manual correction.
Common uses
- Headings and titles
- UI labels
- Content cleanup
- Email and document editing
- Normalizing copied text
Privacy and browser-side processing
