How to use ROT47 a String
- 1. Paste your text. Enter the text you want to encode or decode into the input pane, such as Hello, including any punctuation or symbols you want rotated too.
- 2. Read how the cipher works. There are no settings; every printable ASCII character from the visible range is rotated 47 positions within that range, covering letters, digits and punctuation together, unlike ROT13 which only touches letters.
- 3. Copy the transformed text. Copy the scrambled result from the output pane, such as w6==@, and run it back through the same tool to decode it since ROT47 is symmetric.
When to use ROT47 a String
ROT47 a String extends the ROT13 idea to the whole printable ASCII range, rotating letters, digits and punctuation alike, which makes it obscure more of a message than ROT13's letters-only rotation. Use it for spoilers, puzzle answers and playful obfuscation that includes symbols and numbers.
- Obscuring a message that relies on punctuation. A joke or spoiler message depends on specific punctuation, like an emoticon or symbol, that ROT13 would leave untouched and readable. ROT47 rotates those characters too for fuller obfuscation.
- Hiding a code snippet from a casual glance. You want to share a short code snippet in a forum post without it being immediately legible or accidentally executed by a copy-paste. ROT47 scrambles it while keeping it reversible.
- Comparing ROT13 and ROT47 side by side. You're demonstrating the difference between letter-only and full-ASCII rotation ciphers, and running the same input through both tools shows exactly what each one leaves untouched.
- Encoding a puzzle answer that includes symbols. A puzzle's answer includes special characters as part of the format, and you want the published solution to stay obscured until a solver decides to decode it.

About the ROT47 a String tool
ROT47 a String does its work locally, right in the browser. Encode or decode a string with the ROT47 cipher over printable ASCII. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the String Tools collection on EditSafely, a set of 159 small, focused String utilities that share the same instant, private workspace.
There is nothing to configure. Provide the input and the result appears on its own. 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
Is ROT47 a String free to use?
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?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
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?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
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.
