What is URL Encode?

URL encoding (percent-encoding) converts characters into a format that can be safely transmitted over the Internet in URLs. It replaces unsafe ASCII characters and non-ASCII characters with a "%" followed by two hexadecimal digits representing the character's byte value.

How to Use URL Encode

1. Enter or paste your text into the input field. 2. The URL encoded result appears instantly in the output field. 3. Click "Copy" to copy the encoded text to your clipboard. 4. Use "Clear" to reset and start over.

When to Use URL Encode

Use URL encoding when building query strings, encoding form data for POST requests, or including special characters in URLs. Essential for API calls with parameters.

How URL Encode Works

Reserved characters (like ?, &, =, #, /), unsafe characters (like spaces, quotes), and non-ASCII characters are converted to %XX format where XX is the hexadecimal value. For example, a space becomes %20, and "hello world" becomes "hello%20world". This ensures URLs remain valid across different systems.

Common Use Cases

  • Query string parameters
  • Form data submission (application/x-www-form-urlencoded)
  • Encoding file names in URLs
  • API request parameters
  • OAuth redirect URIs
  • Search engine queries
  • Deep linking with special characters

FAQs

1 What is URL used for?

URL is primarily used for query string parameters, form data submission (application/x-www-form-urlencoded), and many other applications where url encoding is needed.

2 Is URL secure?

URL is an encoding method, not encryption. It provides no security and can be easily reversed.

3 Is this tool safe to use?

Yes! All encodeing happens in your browser. Your data never leaves your device and is not sent to any server.
