Key Capabilities
What is ROT13?
ROT13 is a simple letter substitution cipher that replaces each letter with the letter 13 positions ahead in the alphabet. Since the alphabet has 26 letters, applying ROT13 twice returns the original text. It's used to hide spoilers, puzzle answers, and mildly obscure text — not for security.
Who uses this tool professionally?
Online forum moderators encode spoiler content so readers can choose to decode it. Puzzle designers create ROT13-encoded hints and answers. Programmers use ROT13 as a simple obfuscation for test strings and email address harvesting prevention.
Is ROT13 secure encryption?
No. ROT13 provides zero security — it's trivially reversible and is not encryption by any modern definition. It's purely a text obfuscation convention used for casual concealment of text content, not for protecting sensitive information.
Is my text kept private?
Yes. All encoding/decoding happens locally in your browser. Text is never sent to any server.
