How do you convert ROT13 to text?
ROT13 shifts every letter thirteen places, so Uryyb decodes to Hello and Hello encodes to Uryyb using the identical operation. Thirteen is half the alphabet, which is why one tool handles both directions. Digits, spaces and punctuation pass through untouched. Use it for spoilers and puzzle answers; it hides text from a glance, not from anyone determined.
How to use the ROT13 to Text
- 1 Paste either plain text or ROT13 text; the operation is the same.
- 2 Each letter rotates thirteen places; everything else stays.
- 3 Apply it a second time if you need the original back.
- 4 Copy the converted message.
What you can use it for
- Hiding spoilers or punchlines in forum posts.
- Obscuring puzzle or quiz answers.
- Decoding ROT13 text you have received.
- Demonstrating a basic substitution cipher.
Frequently asked questions
Why is there no separate encode and decode mode?
Shifting by thirteen twice moves each letter the full twenty-six places, back to its start. One operation covers both directions, so one button is enough.
Are numbers and symbols rotated as well?
No, only A to Z in either case. Everything else, including digits, spacing and punctuation, passes through, which preserves the layout of the message.
Should I use ROT13 to protect anything sensitive?
Never. It is a readability screen, not encryption: anyone can reverse it in a second. It suits spoiler warnings and puzzle answers, nothing more.
