About Base32 Decode

Base32 Decode is a free online tool that converts Base32-encoded strings back into readable plain text. Base32 is a binary-to-text encoding scheme that uses 32 characters (A-Z and 2-7) and is commonly used in two-factor authentication (TOTP/HOTP) secret keys, DNS records, and case-insensitive systems where Base64 would not be appropriate.

All decoding happens entirely in your browser using JavaScript — no data is ever sent to a server. The tool correctly handles padding characters and supports UTF-8 encoded content, so it can decode text in any language that was originally Base32-encoded.

Frequently Asked Questions

What is Base32 Decode? expand_more
Base32 Decode is a free online tool that converts Base32-encoded strings back into their original plain text form. It reverses the Base32 encoding process, transforming the 32-character representation (A-Z, 2-7) back into readable text.
What is Base32 used for? expand_more
Base32 is commonly used for TOTP/HOTP secret keys in two-factor authentication apps like Google Authenticator, DNS record encoding, Onion addresses in Tor, and any system that requires case-insensitive encoding.
Is my data secure? expand_more
Yes. All decoding happens entirely in your browser using JavaScript. No data is sent to any server, ensuring your encoded data remains completely private and secure.
What if my Base32 string is invalid? expand_more
If the input contains characters outside the Base32 alphabet (A-Z, 2-7, =), the tool will display a clear error message identifying the invalid character.
