• Case transforms use standard JavaScript string methods.
• Title case capitalizes the first letter of each whitespace-separated word.
• Sentence case capitalizes the first letter after sentence-ending punctuation.
• Whitespace cleanup collapses repeated spaces and trims ends while preserving paragraph breaks where practical.

• Any plain text pasted or typed into the browser

• Title case does not apply language-specific rules for names, particles, or acronyms.
• Results may look imperfect for some non-English scripts or mixed-language text.
• This tool does not rewrite grammar or meaning, only case and spacing.

This tool runs in local-only mode. Your text or files are processed in your browser and are not uploaded to our servers for this feature. Keep originals on your device; downloads create a separate copy.

Does title case handle names correctly?

Not always. Title case here is a simple word-by-word capitalization. Names like McDonald or particles like von may need manual adjustment.

Is text stored anywhere?

No. Conversion happens locally in your browser and is not uploaded.
