Quick Start

  1. Visit HeronTool homepage and select the "Decode" toolset.
  2. Choose the tool based on data type: plain text decode, URL decode, or QR code decode.
  3. Paste or upload the data, click "Decode", and the result appears instantly.

Specific Scenarios

  • Base64 / URL Decoding: Copy the encoded string, paste it into the text input, click "Decode", and see the original text. Great for handling garbled emails or link parameters.
  • JWT Decode: Paste a JWT token into the "JWT Decoder" tool; it automatically splits into Header, Payload, and Signature, helping you debug login logic quickly.
  • QR Code Decode: Upload a QR code image to the "QR Code Reader", or drag and drop the file, and the tool extracts embedded info like URLs, text, or contact data.

FAQ

  • Q: Garbled text after decoding? A: Check the original encoding (e.g., UTF-8, GBK), try switching encoding options or use "Auto Detect".
  • Q: Unclear QR code image? A: Ensure the image is sharp and unobstructed; try higher resolution or re-capture.
  • Q: JWT decode fails? A: Confirm the token is complete and not expired, and check for extra whitespace.
