URL Encoder/Decoder - Encode and Decode URLs Online Free

What is URL Encoder/Decoder?

Our URL Encoder/Decoder is a 100% free, browser-based tool that allows you to easily encode plain text into URL-safe formats (converting spaces to %20, special characters to hex values, etc.) or decode complex percent-encoded strings back to human-readable text. It operates entirely client-side, using standard JavaScript APIs (`encodeURIComponent` and `decodeURIComponent`) for instantaneous processing without any network overhead, ensuring your data remains fully private.

Key Advantages of Client-Side URL Conversion

  • 100% Client-Side & Private: All encoding/decoding processes run inside your browser. No URLs or queries are sent to our servers.
  • Instant Processing: Built-in high-performance browser functions convert long text payloads in milliseconds.
  • Granular Encoding Modes: Choose between `encodeURIComponent` (encodes all special characters) and `encodeURI` (retains standard URL structure keys like /, ?, &, =).
  • Offline Capability: Works completely without an active internet connection.
  • Error Detection: Catches malformed percent-encoding anomalies and displays friendly troubleshooting tips.

How to use URL Encoder/Decoder

  1. Step 1: Choose your conversion mode - 'Encode' or 'Decode' using the main buttons.
  2. Step 2: Enter or paste your string/URL into the Input panel.
  3. Step 3: Select your preferred setting (Encode component vs. full URL).
  4. Step 4: The result displays immediately in the Output panel (if Auto-Convert is enabled), or click 'Convert' manually.
  5. Step 5: Copy the result to your clipboard or download it as a text file.
