URL Encoder & Decoder

Encode text strings into percent-encoded format or decode URL query strings back to readable characters instantly.

Converts instantly as you type

URL Delimiters

Certain characters have specific syntactic meaning in URLs. For example, ? starts the query string, & separates key-value parameters, and = links values. Encoding prevents overlaps.

Common Escapes

  • Space: %20
  • Slash (/): %2F
  • Question (?): %3F
  • Ampersand (&): %26
  • Equals (=): %3D

Complete Guide: How to Use the URL Encoder & Decoder

Formatting strings for API endpoints, encoding search queries, and resolving percent-encoded redirect chains are standard requirements in modern web development. Our free URL Encoder and Decoder translates URL component paths or parameter query strings in real-time, executing securely on client-side JS.

Step-by-Step Instructions

  1. Choose the encoding mode: 'Encode Component' (escapes all special characters, ideal for query parameters) or 'Encode Full URI' (preserves protocol scheme, slashes, and question marks).
  2. To Encode: Enter or paste your standard text or URL in the 'Decoded Plain Text' input field. The percent-encoded result generates instantly in the 'Encoded URL Output' box.
  3. To Decode: Paste a percent-encoded string (containing characters like %20, %2F) in the 'Encoded URL Output' field. The parsed readable text appears instantly.
  4. Click 'Copy' next to either input box to save the respective outputs.

Key Features & Benefits

  • Instant Fluid Conversions: Encodes or decodes text dynamically as you type.
  • Dual Encoding Modes: Choose between encoding query parameters (`encodeURIComponent`) or whole URL paths (`encodeURI`).
  • Error-Tolerant Decoder: Handles malformed percent escapes and reports issues without breaking page logic.
  • No Network Overhead: Evaluates conversions strictly on the client side, keeping secret tokens or query parameters confidential.
