What It Does
Encode or decode text using ROT47 cipher, which rotates ASCII printable characters by 47 positions. This extended version of ROT13 handles numbers and symbols in addition to letters, making it useful for obfuscating a wider range of text content while remaining easily reversible.
Common Use Cases
- Obfuscating text that includes numbers and special characters
- Creating reversible encoding for ASCII content
- Hiding spoilers or answers that contain symbols
- Learning about extended rotation ciphers
- Processing data that ROT13 cannot fully handle
How to Use
- Enter or paste the text you want to encode or decode
- ROT47 transformation is applied automatically
- The same operation decodes previously encoded text
- Copy the result for sharing or storage
Features
- Handles all 94 printable ASCII characters
- Self-reversing - apply twice to get original
- Includes numbers and punctuation in rotation
- Instant encoding and decoding
Examples
Below is a representative input and output so you can see the transformation clearly.

Edge Cases
- Very large inputs may take a few seconds to process in the browser. If performance slows, split the input into smaller batches.
- Mixed formatting (tabs, line breaks, or inconsistent delimiters) can affect output. Normalize spacing first if needed.
- ROT47 Text follows the selected options strictly. If the output looks unexpected, re-check option settings and input format.
Troubleshooting
- Output looks unchanged: confirm the input contains the pattern this tool modifies and that the correct options are selected.
- Unexpected characters: check for hidden whitespace or encoding issues in the input and try normalizing first.
- Slow processing: reduce input size or try a modern browser with more available memory.
Frequently Asked Questions
Is my input stored or logged?
No. This tool is designed to run in your browser, and we do not store or log your content during processing.
Is conversion instant?
Yes for most inputs. Output updates immediately, and large inputs may take a moment depending on your device.
Can this handle large text?
It can handle large text, but performance depends on your browser and device. For very large files, consider splitting the input.
Does it support mobile?
Yes. The interface is responsive and works on phones and tablets, so you can use it on the go.
Can I use it for commercial projects?
Yes. You are free to use the output in personal or commercial projects without attribution.
Does this affect numbers or punctuation?
Only if the selected options target them. Otherwise, numbers and punctuation are preserved as-is.
