URL Percent Encoder & Decoder

Safely format web URLs and API query strings by encoding reserved characters into percent-encoded entities or decoding URL strings back to clean text.

  • Choice between component encoding or full URL sanitization.
  • Real-time live processing.
  • Handles multilingual UTF-8 characters.

How to Use:

  1. Paste your URL or parameter text.
  2. Select Encode or Decode.
  3. Copy your sanitized URL parameter instantly.

Why URL Encoding is Necessary

URLs can only be sent over the internet using the ASCII character-set. Non-ASCII and reserved symbols (like ?, &, =) must be percent-encoded.

Frequently Asked Questions:

%20 is standard percent-encoding in URL paths and queries; the plus symbol (+) is commonly used in query string forms (application/x-www-form-urlencoded).
