Frequently Asked Questions

What's the difference between Title Case and Capitalized Case?

Title Case capitalizes the first letter of most words (following standard title formatting rules), while Capitalized Case capitalizes the first letter of every word regardless of grammar rules. Our tool offers both options for different needs.

Can the tool handle special characters or formatting?

Yes. The tool preserves numbers, symbols, and special characters while only modifying the letter casing. Basic formatting like line breaks and paragraphs are maintained, though advanced formatting (bold, italics, etc.) in rich text may be lost when pasting from formatted sources.

Is there a limit to how much text I can convert at once?

There is no practical limit for standard use. You can convert entire documents, chapters, or lengthy articles. The tool processes text efficiently regardless of length, though extremely large texts (over 1 million characters) may experience slight browser performance considerations.

Does the tool work with non-English languages?

The basic case conversion functions work with any language using the Latin alphabet. For languages with different capitalization rules or non-Latin scripts, the UPPERCASE and lowercase functions will work, but Title Case may not apply language-specific rules correctly.

Is my text secure when using this tool?

Absolutely. Unlike many online tools, our Case Converter processes your text entirely in your browser—your text never leaves your device or gets transmitted to our servers. This provides maximum privacy and security for sensitive or confidential content.
