ABOUT
What this site does
StringMash turns text into Morse, runes, Ogham, Base64, binary, character codes and the classic puzzle ciphers. Type on one side and the result appears on the other. There's no convert button anywhere on the site.
Every converter that can run backwards does, and the arrows between the boxes re-run what you typed in the other direction. Where a conversion only goes one way, like Pig Latin, the page says so instead of guessing.
Holding something unreadable? Start at the cipher identifier, which tries every conversion here and ranks what comes back.
