About this Base32 Encoder / Decoder

Encode any text or binary data to Base32 (RFC 4648) and decode Base32 back to plain text — all inside your browser. Base32 uses 32 case-insensitive characters (A–Z and 2–7) which makes it safer than Base64 for URLs, DNS names, filenames and OTP secrets, since it avoids look-alike characters and works when case is not preserved. Paste input on the left, get the result instantly on the right, and copy with one click. Nothing is uploaded — the whole conversion runs locally.

Frequently asked questions

How is Base32 different from Base64?

Base32 uses 32 characters instead of 64 and is case-insensitive, so it survives systems that upper-case text (DNS, some filesystems). Output is roughly 60% longer than Base64, but far safer for URLs, IDs and OTP secrets.

Does this support TOTP / 2FA secrets?

Yes. TOTP shared secrets are Base32-encoded by convention. Paste the Base32 string to see the raw bytes, or encode raw bytes to a Base32 secret you can paste into Google Authenticator, Authy or 1Password.

Is my data uploaded?

No. Encoding and decoding happen 100% in your browser using JavaScript — no request is ever sent, and nothing is stored.
