BIP39 Word Selector

Bidirectional Bitcoin BIP39 mnemonic word selector and converter tool

An interactive, privacy-focused web application for exploring the BIP39 wordlist. Type words or click numbers. Perfect for understanding how Bitcoin seed phrases work.

How It Works

Method 1: Type a Word

Simply type any BIP39 word in the input field. The numbers will automatically update to show the binary pattern.

Method 2: Click Numbers

Click the number boxes (2048, 1024, 512, etc.) to create a binary pattern. The corresponding BIP39 word appears automatically.

Each number represents a binary bit. Combining them creates values from 1-2048, matching the 2048 BIP39 words.
