What is URL Encoder/Decoder?

URL Encoder/Decoder translates special characters into a URL-safe format using percent-encoding (e.g., a space becomes %20), and reverses the process. This ensures that query parameters, complex paths, and API requests transmit correctly over the internet.

  1. Choose to either Encode or Decode
  2. Paste your string or URL into the text area
  3. Click to convert
  4. Copy the resulting URL-safe string
