Can I swap letters across word boundaries or only within words?

The tool swaps adjacent letters within each individual word, keeping word boundaries intact so that letters do not move between separate words.

What happens if a word has an odd number of letters?

In words with an odd number of characters, the final letter stays in its original position while all preceding pairs are swapped.

Does the tool handle punctuation and numbers within text?

Punctuation and numbers are treated as part of the word structure, so they are swapped along with adjacent letters within each word token.

Is there a limit to how much text I can process at once?

The material does not specify a character limit, but very large passages may take longer to process depending on the site's implementation.

What Swap Letters in Words does

Swap Letters in Words is a straightforward text utility that reverses the order of every adjacent character pair within each word of a given passage. Users input their text and receive a transformed version where letters like "ab" become "ba" throughout, preserving the original word structure while altering the visual arrangement. This creates a simple form of wordplay that can produce humorous or cryptic effects without changing the underlying vocabulary. The output maintains the same word boundaries and spacing as the input, making the results immediately comparable to the source material.
