Can I control how many times each letter is repeated?

No, the tool doubles every character in the input; there is no setting to adjust the repetition count beyond this default behavior.

Does the tool preserve spaces and punctuation in the output?

Yes, spaces and punctuation marks are treated as characters and are repeated twice along with the letters, maintaining the original structure of the text.

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

The material does not specify a character limit, but very long inputs will produce proportionally longer outputs that may be difficult to manage or copy.

Can I use this tool for languages other than English?

The tool processes any characters provided in the input field, so it should work with text in various languages, repeating each character according to the same rule.

What Duplicate Letters does

Duplicate Letters is a straightforward text expansion tool that repeats every character in a given string. Users paste their desired message into the input field, and the tool generates a new sequence where each letter appears twice in its original order. This process effectively lengthens the text, doubling every character while preserving the overall structure of the input. It serves as a simple utility for creating visually expanded text versions of any message or phrase.
