DEV 🔐 Encoding

URL Encoder / Decoder

URL encoding (percent-encoding) converts special characters into a safe format for web transmission. Spaces become %20, ampersands become %26, etc. This is essential for building query strings and safe URL construction.

How to Use

  1. Select Encode to percent-encode a URL or text string, or Decode to reverse the process.
  2. Enter your URL or text in the input panel.
  3. Click Transform to encode or decode.
  4. Encoded URLs can be safely used in query strings, forms, and API calls.

How It Works

Each byte of the input string is converted to a two-digit hexadecimal value prefixed with a percent sign (%). Characters that are already safe for URLs (letters, numbers, - _ . ~) may be preserved or encoded depending on the implementation.
