Encode text to Base32 or decode Base32 strings back — the alphabet TOTP apps and authenticator URIs use. Both directions, fully local.

Encode special HTML characters into entities (& < >) or decode them back to readable text — display code safely and neutralize injection vectors.
Encodes text or small files into Base64 strings and decodes them back with automatic MIME-type detection for binary safety. Code never leaves your device — formatting and validation run locally in your browser.
Encode or decode URLs with percent-encoding. Swaps input/output for quick bidirectional conversion. Code never leaves your device — formatting and validation run locally in your browser.
Convert between plain text and binary in both directions — encode text into its base-2 representation or decode binary strings back to readable text, byte by byte. Files are converted locally in your browser — nothing is uploaded.
Decode binary strings back to readable Unicode text with strict validation. Recover messages from bit dumps — local decoding, free, no signup.
Base32 encodes binary data into 32 ASCII characters (A-Z, 2-7). It produces longer output than Base64 but is human-readable and avoids ambiguous characters.
Use Base32 when you need human-readable encoding (TOTP secrets, QR codes) or systems that only support uppercase letters. Base64 is more compact for general use.
Yes. UTF-8 text is properly encoded to Base32 and decoded back to the original text, preserving all characters including non-ASCII.
Yes. Paste a Base32 string and the tool decodes it to the original text. The tool handles both standard and padded Base32 formats.
Yes. All encoding and decoding happens in your browser. No data is transmitted to any server.
