How to Use the American-British Spelling Converter
Writing in English often means mixing spellings that differ between American and British English — color vs. colour, organize vs. organise, and dozens more. A document meant for American readers with British spellings scattered through it (or vice versa) can look inconsistent. Paste your text here, choose a direction, and this tool automatically finds and converts every matching word.
Here's how it works: paste your English sentence or document into the text box, then choose "American → British" or "British → American." The tool recognizes more than 55 real, commonly used word pairs — color/colour, organize/organise, center/centre, theater/theatre, traveling/travelling, and more — and preserves the original capitalization in the output (Color becomes Colour, COLOR becomes COLOUR). Words outside this list are left exactly as written.
Alongside the converted text, you'll see how many words were changed, making it easy to check spelling consistency across an entire document. It's handy for tailoring content, papers, or emails for a specific regional audience before you send them out.
