## Description

This extension makes it easy to work with encoded or formatted text without leaving your browser. Just highlight some text, right-click, and choose Decode to automatically detect the format — or use Encode to convert it into something else.

It supports many common formats, including:

Base64

Hexadecimal

Binary (8-bit)

ASCII codes

URL encoding

Morse code

ROT13 / Caesar cipher

Text transformations (uppercase, lowercase, reverse)

Whether you’re a developer checking encoded data, a student experimenting with ciphers, or just curious what a string of symbols means, this add-on saves time by keeping everything one click away.

No complicated settings, no clutter — just highlight, right-click, and go.
