What does Base32 Decode do?

Base32 Decode turns encoded text back into the original instantly, as you type or when you press the button.

Base32 uses only capital letters A–Z and digits 2–7, so it survives case-insensitive systems. You’ll see it in two-factor (TOTP) secret keys.

What you can use

Encoded text, exactly as you copied it — extra spaces or missing characters at the end will cause errors.

Example

Input

JBSWY3DP

Output

Hello

Good to know

  • Encoding is reversible and is not a way to hide secrets — use real encryption for anything sensitive.
  • If the output looks like random symbols, the input was probably encoded with a different scheme or was cut off.

Frequently asked questions

Is Base32 Decode free?

Yes. Base32 Decode is completely free, with no sign-up, no watermark and no daily limit.

Is the data I paste sent to a server?

No. Conversion runs in JavaScript inside this browser tab and nothing you paste is sent or stored. Even so, avoid pasting live passwords, API keys or private customer data into any website.

Why do I get an error?

Almost always the input isn’t quite valid: a missing comma or quote in JSON, an unclosed tag in XML, or a tab in YAML. The error message shows where parsing stopped — fix that spot, or press “Load example” to compare with input that works.

Does it work on my phone?

Yes. It works in any modern browser on Android, iPhone, tablets and computers — nothing to install.
