🔤 Base32 Encoder / Decoder
Convert binary data to/from clean alphanumeric Base32 (RFC 4648). Supports text and file input. Fully client‑side, no data leaves your device.
📖 How to Use Base32 Encoder / Decoder (Step by Step)
- Step 1: Enter text or upload a file into the left panel.
- Step 2: Click "Encode → Base32" to convert to Base32, or "Decode ← From Base32" if you have a Base32 string.
- Step 3: The result appears in the right panel. You can copy it or swap it with the input field.
- Step 4: Use the "Load Example" button to test with a sample text.
- Step 5: For binary files (images, documents), the tool will decode Base32 to a hex preview if the data is not plain text.
💡 What is Base32?
- ✔️ Base32 uses a 32‑character set (A‑Z, 2‑7) – compact and URL‑safe.
- ✔️ Commonly used for TOTP secrets, DNS records, and email hashes.
- ✔️ This tool follows RFC 4648 with padding (=).
💡 Pro Tip: Base32 is case‑insensitive and ignores spaces. Use it when you need alphanumeric encoding that is safer than Base64 in some contexts (e.g., DNS, filenames).
🔒 100% client‑side • Your data never uploaded • RFC 4648 compliant • Zero tracking
