How to use ROT47 Text
- 1. Paste the text to rotate. Paste text into the input pane, including numbers, punctuation and symbols, since ROT47 covers the full range of printable ASCII characters, not just letters.
- 2. Read how the rotation works. The tool has no settings; each printable ASCII character is rotated 47 positions within that range, and running the output through again restores the original.
- 3. Copy the rotated text. Copy the ROT47 result from the output pane and paste it wherever a slightly stronger obfuscation than ROT13, covering symbols and digits too, is useful.
When to use ROT47 Text
ROT47 Text encodes or decodes text with the ROT47 cipher, which extends the ROT13 idea across the full printable ASCII range instead of just letters. It scrambles numbers and symbols along with words, and applying it twice restores the original.
- Obscuring a message that includes numbers. A spoiler or answer includes numeric codes or symbols alongside words, and ROT13 alone would leave those characters readable, so ROT47 scrambles the whole string uniformly.
- Encoding a URL or email address playfully. You want to lightly obscure a link or address in a forum post so it isn't immediately clickable or searchable, and ROT47 handles the slashes and symbols too.
- Comparing cipher coverage in a lesson. Explaining the difference between ROT13 and ROT47 is clearer with a live example showing how ROT47 also scrambles digits and punctuation that ROT13 leaves alone.

About the ROT47 Text tool
ROT47 Text is a free online tool that works entirely inside your web browser. Encode or decode text with the ROT47 cipher over printable ASCII. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 211 Text utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
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.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is ROT47 Text 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.
