How to use Duplicate Letters in Text
- 1. Paste the text to stretch. Paste a word or phrase into the input pane, one you want stretched by repeating some or all of its letters a set number of times.
- 2. Choose which letters and how many copies. Type specific letters into Only these letters (blank = all), leaving it blank to duplicate everything, and set Copies to how many times each targeted letter repeats.
- 3. Copy the stretched text. Copy the result from the output pane, with letters repeated the number of times you chose, and paste it into a message, caption or stylized text.
When to use Duplicate Letters in Text
Duplicate Letters in Text repeats each letter, or only the letters you choose, a set number of times, stretching out words for emphasis or effect. Reach for Duplicate Letters in Text whenever you want text drawn out the way excited speech reads.
- Writing an excited exclamation for social media. A caption reading 'so goooood' or 'yesss' captures excitement better than the plain word, and setting a duplicate count stretches specific letters exactly how you want.
- Stylizing a word for a header or logo mockup. A playful header design stretches out select letters of a word for visual emphasis, and choosing which letters to duplicate keeps the rest of the word intact.
- Generating stuttered dialogue for a script. A character's stuttered speech in a script or story needs a specific letter repeated at the start of a word, and targeting just that letter here produces the effect.
Examples
Double every letter
Input
hello

hheelllloo
About the Duplicate Letters in Text tool
Duplicate Letters in Text does its work locally, right in the browser. Repeat each letter (or only chosen letters) a number of times. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Text Tools collection on EditSafely, a set of 211 small, focused Text utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Only these letters (blank = all) and Copies, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does Duplicate Letters in Text cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
