What is a capitalize text tool?
A capitalize text tool changes the letter case of your text without retyping it. It can capitalize the first letter of every word, capitalize only the first letter of each sentence, or switch everything to uppercase or lowercase. It is handy for headlines, product names, social posts, spreadsheet cleanup, and text pasted from sources with messy formatting.
How to capitalize text online

- Choose a conversion mode: Title Case, Sentence case, UPPERCASE, or lowercase.
- Check the converted text. It updates as you type.
- Select “Copy result” and paste the text where you need it.
Title Case vs. Sentence case
Title Case capitalizes the first letter of every word. Sentence case capitalizes only the first letter of each sentence, the way normal writing works.
| Mode | Input | Output |
|---|---|---|
| Title Case | hello WORLD | Hello World |
| Sentence case | hello world. welcome back. | Hello world. Welcome back. |
| UPPERCASE | hello world | HELLO WORLD |
| lowercase | Hello World | hello world |
What to check by hand
This tool uses simple, predictable rules. Title Case here capitalizes every word, so small words such as “and”, “of”, and “the” are capitalized too. Style guides like APA, AP, and Chicago handle those words differently. Brand names such as iPhone or OpenAI are lowercased and then re-capitalized by the same rule, so review them before publishing. In Sentence case, abbreviations like “e.g.” can trigger a capital letter on the next word.
