Smart Title Case Conversion

One thing that sets our tool apart: smart title case. Most converters capitalize every word, including small words like "and," "the," "of," and "in." Our tool knows the rules and properly handles:

• Small words that should stay lowercase (a, an, the, and, or, but, for, nor, so, yet)
• Prepositions under 5 letters (at, by, for, in, of, on, to, up)
• The first and last words always get capitalized
• Words after colons get capitalized

This follows Chicago Manual of Style and AP Style guidelines the standards most publications use.

Privacy-Focused

Like all our tools, this case converter runs entirely in your browser. Your text never leaves your device, and there's no way for us (or anyone else) to see what you're converting.
