Word Shuffler is a free tool that runs entirely in your browser, with no data ever sent to a server. Shuffle the letters of each word at random, keeping the ends in place if needed.

What it's for

Create a little word-guessing game, or illustrate a well-known reading effect: as long as the first and last letter stay in place, most readers decode the word effortlessly, even with the middle completely scrambled.

What this tool does not do

This tool only applies the transformation described, with no spellchecking and no interpretation of the text's meaning. A text of several tens of thousands of lines processes instantly; beyond that, the only limit is your device's memory.

Frequently asked questions

Are words of two letters or fewer shuffled?

No: a word of at most two letters has no middle to shuffle, so it stays unchanged.

Is my data sent to a server?

No: the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?

No: the tool works directly in this page, with no sign-up and nothing to install.
