Input
What is Base32 Encode?
Base32 is a binary-to-text encoding using 32 printable characters (A-Z and 2-7), designed to be more human-readable and error-resistant than Base64. It's commonly used in applications where data might be manually typed or spoken, like two-factor authentication (2FA) codes.
How to Use Base32 Encode
1. Enter or paste your text into the input field. 2. The Base32 encoded result appears instantly in the output field. 3. Click "Copy" to copy the encoded text to your clipboard. 4. Use "Clear" to reset and start over.
When to Use Base32 Encode
Use Base32 encoding for 2FA secret keys, QR codes, or when you need case-insensitive encoding that's easy to type manually.
How Base32 Encode Works
Base32 divides binary data into 5-bit chunks (2^5=32 values), maps each to characters A-Z and digits 2-7 (avoiding 0/O and 1/I/L confusion), and pads with "=" to complete 40-bit blocks. The encoding expands data size by approximately 60%.
Common Use Cases
- Two-factor authentication (TOTP/HOTP)
- QR codes for 2FA apps
- Human-readable identifiers
- DNS-safe encoding
- Case-insensitive systems
- Torrent magnet links
Security Note
⚠️ Base32 is encoding, not encryption. It provides no security and is easily decoded.
FAQs
1 What is Base32 used for?
Base32 is primarily used for two-factor authentication (totp/hotp), qr codes for 2fa apps, and many other applications where base32 encoding is needed.
2 Is Base32 secure?
Base32 is an encoding method, not encryption. It provides no security and can be easily reversed. Never use it to protect sensitive data.
3 Is this tool safe to use?
Yes! All encodeing happens in your browser. Your data never leaves your device and is not sent to any server.
