Title Case Converter

What the Title Case Converter Does

Type or paste your text and every word comes back with its first letter capitalised and the remaining letters lowercased. It is the quick way to tidy an all-lowercase or shouty heading into a consistent capitalised form.

This is 'capitalise each word' style — sometimes called start case. It is simple and predictable, but it is not the title case a style guide would apply, which keeps certain small words lowercase. If you need strict AP or Chicago title case, you will tweak a few words by hand.

How It Works

The tool finds each word — a run of characters starting with a letter or digit — and rewrites it so the first character is uppercase and everything after it is lowercase. Punctuation and spacing are left in place, so hyphenated and apostrophised words keep their shape.

Because it lowercases the rest of each word, anything that was intentionally capitalised inside a word is flattened: an acronym like NASA becomes Nasa, and a name like iPhone becomes Iphone. The rule is purely mechanical — first letter up, rest down — with no dictionary of exceptions.

Data source & conversion logic

1. Find each word. Split the text into words, starting at each letter or digit.
2. Capitalise the first letter. Make the first character of each word uppercase.
3. Lowercase the rest. Make the remaining characters of each word lowercase.
4. Keep spacing and punctuation. Leave spaces, hyphens and other punctuation exactly as they were.

Worked example

It capitalises every word; a style guide would keep small words like 'of' and 'the' lowercase.

Technical Details

Standards & references

• Title case (editorial) — in AP and Chicago style, title case capitalises the main words but keeps articles (a, an, the), short conjunctions and short prepositions lowercase — unless they are the first or last word. This tool does not apply those exceptions.
• Capitalise each word (start case) — this tool uses the simpler rule of capitalising the first letter of every word, which is consistent but not what a style guide calls title case.
• First-letter only — it lowercases the rest of each word, so acronyms and mid-word capitals (NASA, iPhone) are flattened and need fixing by hand.

Accuracy & Limitations

It capitalises every word, including small words that editorial title case keeps lowercase. So it gives The Lord Of The Rings, where AP or Chicago style would give The Lord of the Rings. For strict style-guide title case, lowercase the minor words yourself afterwards.

It lowercases the rest of each word, which flattens intentional capitals. NASA becomes Nasa, iPhone becomes Iphone, and PhD becomes Phd; restore those by hand if they matter.

There is no dictionary of exceptions. The rule is mechanical — first letter up, rest down — so it cannot know that a particular word is a brand, an acronym or a minor word.

It works word by word using letters and digits as boundaries, so hyphenated words have each part capitalised (well-known becomes Well-Known) and apostrophised words keep their shape (don't becomes Don't).

It is for Latin-script and similar cased text. Capitalisation only applies to scripts that have upper and lower case; characters in scripts without case pass through unchanged.

Real-World Use Cases

When to use it — and when not to

Need true editorial title case with lowercased minor words? Apply this first, then lowercase the small words by hand, or use a style-specific title-case tool. Want only the first letter of the sentence capitalised? Use a sentence-case option.
