Why use this Capitalize Words tool?
Manually capitalizing the first letter of each word is tedious and error‑prone. This tool does it instantly, with an option to also lowercase the rest of the letters for a clean, consistent look. It's perfect for titles, headings, or fixing caps‑lock mistakes.
- Smart word detection – recognizes words separated by spaces, punctuation, and newlines.
- Optional lowercasing – when enabled, the rest of each word is converted to lowercase, giving you proper title case (e.g., "hELLO" → "Hello").
- Instant preview – output updates as you type (with a short delay) or when you click Capitalize.
- 100% private – all processing is done locally; your text never leaves your device.

Common use cases
- Title formatting: Quickly format blog post titles, article headlines, or book titles.
- Name correction: Fix lowercase names in a list before importing into a CRM.
- Accidental caps lock: Repair text that was typed in all caps or all lowercase.
- Data cleaning: Standardize the casing of keywords or product names.
Pro tips
- Words connected by hyphens or apostrophes (like "self-aware" or "don't") are treated as single words. The first letter of the entire word is capitalized.
- If you need different title case rules (e.g., lowercasing short words like "a", "an", "the"), you might combine this tool with a manual edit afterwards.
