About Multi Text Encoder/Decoder

Process text using various encoding and decoding methods for web development, data processing, and security applications.

Supported Operations:
URL Encoding/Decoding
  • URL Encode: Convert special characters to percent-encoded format (%20, %21, etc.)
  • URL Decode: Convert percent-encoded characters back to original form
  • Use Case: Preparing text for URL parameters, form data transmission
HTML Entity Encoding/Decoding
  • HTML Encode: Convert special HTML characters (<, >, &, etc.)
