Frequently Asked Questions
What is text case conversion?
Text case conversion changes the capitalization of letters in your text. This includes converting to all uppercase, all lowercase, capitalizing the first letter of each word (title case), or capitalizing the first letter of each sentence.
How does real-time conversion work?
As you type or change the case style selection, the conversion happens instantly in your browser. No need to click buttons or submit forms - see results immediately as you work.
What text formats are supported?
Our tool works with any text content including plain text, code snippets, documents, social media posts, and more. It preserves formatting like line breaks and handles special characters correctly.
Is there a limit to text length?
There are no artificial limits on text length. The tool processes everything locally in your browser, so performance depends on your device's capabilities. For very large texts, consider splitting them into smaller chunks.
