There’s something timeless about the ROT cipher. Maybe it’s the way it brings a touch of old-school cryptography to your everyday tasks, or maybe it’s just the fun of seeing your words transformed with a single click. I built this ROT Encoder & Decoder for those moments when you want to play with text, hide a message, or just experiment with the basics of encryption—without any hassle.

What makes this tool special is the freedom it gives you. Choose any ROT value from 1 to 25—maybe you want the classic ROT13, or maybe you’re feeling adventurous and want to try ROT7 or ROT21. Type your text, pick your rotation, and watch the magic happen. Need to decode? Just switch tabs, paste your cipher, and you’re back to the original in seconds.

Everything happens right in your browser. No data leaves your device, so you can experiment, encode, and decode with total privacy.
