About the Swap Letters in Words
Our free tool swaps letters within each word of your text according to a simple rule, rearranging characters to create scrambled or altered versions of your words. Type or paste your text and the tool transforms each word instantly while keeping the words in their original positions. It is a fun tool for word games and puzzles, creating obfuscated or playful text, generating typo-style variations, and exploring how readable a word stays when its letters move. Because each word is processed on its own, the overall sentence structure and word count remain the same while the letters within shift. You can copy the result with one click. The whole process runs in your browser and updates the instant you type, so it is immediate, free, and never sends your text to a server.

Which characters are processed?
