ROT47 Encoder and Decoder
What is ROT47 Encoder and Decoder
ROT47 is a variant of ROT13 that rotates the 94 printable ASCII characters (from '!' to '~') by 47 places, so it scrambles letters, digits, and punctuation alike. Like ROT13 it is its own inverse, so one tool encodes and decodes. Spaces and control characters are left unchanged. It runs entirely in your browser.
How to use
- Type or paste your text.
- Read the ROT47 result, updated as you type.
- Paste ROT47 text to decode it: the same rotation reverses it.
- Copy the result or share the link with your text filled in.
When to use it
Need to obscure text that includes numbers and symbols, not just letters? ROT47 scrambles the whole printable ASCII range, so 'Hello' becomes 'w6==@' and digits change too. It is common in CTF puzzles and on Unix systems. Because it is self-inverse, paste the scrambled text back into the same box to recover the original.
Frequently asked questions
How is ROT47 different from ROT13?
ROT13 rotates only the 26 letters. ROT47 rotates all 94 printable ASCII characters, so digits and punctuation change too, and the output looks more scrambled.
How do I decode ROT47?
Paste the ROT47 text into the box. ROT47 is its own inverse, so the same rotation that encodes also decodes.
Is ROT47 secure?
No. It is light obfuscation, not encryption, and takes seconds to reverse. For real protection, use the AES text encryption tool.
Can I share this with my text pre-filled?
Yes. The URL updates automatically as you type. Copy it from the address bar or use the Copy link button, and anyone who opens it sees your exact text ready to go.
