Letter Duplicator

World's Simplest Text Tool

World's simplest browser-based utility for duplicating letters in text. Load your text in the input form on the left and you'll instantly get new text with the original letters repeated several times in the output area. Powerful, free, and fast. Load text – multiply its letters. Created by developers from team Browserling.

᠎᠎᠎          Tool Options

Letters to Duplicate

Don't duplicate these letters.
Letters that should be duplicated.

Number of Copies

Create this number of
letter copies.

Letter Case

When replicating letters, keep
the same letter case as
the original letters.

What Is a Letter Duplicator?

With this online tool, you can replace certain characters and symbols in the given text with multiple copies. For example, you can turn the word "bear" into the word "bbeeaarr" (all characters are doubled) or "bbbeeeaaarrr" (all characters are tripled). You can specify the exact character copy count you need, and the program will multiply and replicate the characters. By default, the program uses the "Duplicate All Letters" mode, which creates copies of all letters in the given text. In this mode, you can also make exceptions for one or more letters by entering them in the "Don't Duplicate These Letters" option. For example, if you ignore the letters "e" and "a" in the word "bear", then the repeated word will be "bbearr". Alternatively, you can switch to the "Duplicate Certain Letters" mode where you can list all the characters that need to be repeated. For example, if you specify only the letter "b", then the word "bear" will become "bbear". Additionally, the program has a "Preserve Letter Case" option, which creates copies of letters in the same case as the original character. For example, when this option is active, the word "Bear" will turn into "BBBear", and when it's disabled, then this word will turn into "Bbbear". Textabulous!


Letter Duplicator Examples

Triple Letters in Text

In this example, we triple all letters in the name of an Internet cat meme. To do this, we turn on the "Duplicate All Letters" mode and enter "3" for the number of copies in the options. We also activate the "Preserve Letter Case" mode which creates copies of the letters "B" and "C" in uppercase.

Double Characters of a Proverb

In this example, we load a proverb into the input area and multiply the characters by two, except for those characters that are found in the word "Rome". That is, the letters "R" (and "r"), "o", "m", "e" are left in their original count.

All roads lead to Rome.

Enhance a Spell

This example reinforces a spell from Harry Potter by quadrupling the number of vowels in the magic phrase. To do this, it uses the "Duplicate Certain Letters" mode, specifies all vowels "aeou" in the option, and sets a four-fold repetition.

Duplicate Vowels in a Name

In this example, we double up all vowels in the name of the only daughter of the Addams Family. There are five vowels in English, which are "aeiou" and we enter these characters in the options. Additionally, we disable the "Preserve Letter Case" option so that the letter "A" is duplicated as "a".

Duplicate All Consonants

This example duplicates the consonants in a one-liner joke about atoms. The consonant letters are all letters of the alphabet except the letters "aeiou" so we enter the alphabet without these letters "bcdfghjklmnpqrstvwxyz" in the options.

Never trust atoms; they make up everything.
