Uppercase Converter: what to know

The uppercase converter turns every letter in your text into a capital letter, keeping numbers, punctuation, spacing and line breaks exactly as they were.

It handles more than A to Z: accented letters (é to É), German ß (to SS), Greek and Cyrillic letters all convert correctly, because it uses the full Unicode case rules rather than a simple English-only table.

Capitals work best in small doses, such as labels, short headings, acronyms and buttons. If you need other cases, the case converter has eleven more, including Title Case and Sentence case.

Popular uses

  • Making headings, labels and signs in capitals
  • Formatting product codes, postcodes and reference numbers
  • Preparing text for forms that require block capitals
  • Creating CONSTANT names for code (or use CONSTANT_CASE)

Tips for the best result

  • Long passages in capitals are harder to read; keep ALL CAPS for short text.
  • Some fonts style text in capitals with CSS instead; changing the text itself is permanent once you paste it.
  • Use CONSTANT_CASE in the case converter if you need underscores between words too.
