Numbers are written differently around the world: Brazil uses a dot for thousands and a comma for decimals, the US does the opposite, and much of Europe uses a space. Documents like CPF, CNPJ, CEP, phone numbers and credit cards each have their own mask. Getting these right by hand is fiddly and error-prone. This free Number Formatter formats numbers in Brazilian, US and European styles, converts between common currencies, and masks Brazilian documents — all instantly in your browser.

How to use the number formatter

  1. Pick a tab: Format a number, convert a Currency, or apply a document Mask.
  2. Type your value — the result updates instantly in every style.
  3. Copy any result with one click.

Why use this tool

  • Brazilian, US and European number styles side by side.
  • Quick currency estimates and CPF/CNPJ/CEP/phone/card masks in one place.
  • Fully client-side: fast, private and free.
