Uppercase Converter

Convert all letters in the text to uppercase.

How to use Uppercase Converter

1. Enter Text. 2. Text remains in the browser. Words are groups of letters or numbers. Apostrophes, hyphens and underscores stay inside a word. Character counts use Unicode code points, which can differ from visible symbols. Some mappings expand a character and proper names/acronyms need review. 3. Select Convert or press Enter from a single-line field. In multiline text fields, Enter inserts a line break. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
