How to Use the URL Encoder & Decoder

When sending data through a web link (URL), you can only use a specific set of safe ASCII characters. If your URL contains spaces, special symbols, or foreign characters, they must be translated into a format that web browsers and servers can understand. Our free URL Encoder / Decoder instantly handles this translation, known as "percent-encoding."

Step-by-Step Instructions:

• Step 1: Paste Your Data. Click inside the top text box and paste the text, query string, or URL you want to convert.
• Step 2: Choose Your Action.
  • Click Encode URL (Blue Button) to translate standard text into a safe format for web transmission (e.g., turning a space into %20).
  • Click Decode URL (Green Button) to translate an ugly, percent-encoded URL string back into human-readable text.
• Step 3: Copy Your Output. Your processed text will appear in the bottom box. Click "Copy Result" to securely save it to your clipboard.
