What does Base32 Encode do?

Base32 Encode encodes your text 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

Any text, including emoji and non-English characters (they are treated as UTF-8).

Example

Input

Hello

Output

JBSWY3DP

How to use Base32 Encode

    Paste the text you want to encode.

  2. Step 2

    Run Base32 Encode. Errors such as invalid characters are shown under the box.

  3. Step 3

    Copy the result with one click.

Good to know

  • Encoding is reversible and is not a way to hide secrets — use real encryption for anything sensitive.
  • Run the matching decoder on the output to check it round-trips back to your original text.

Frequently asked questions

Is Base32 Encode free?

Yes. Base32 Encode 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.
