URL Decode

What is URL Decode?

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 Decode

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

When to Use URL Decode

Use URL decoding to read query parameters, extract data from URLs, or convert percent-encoded strings back to readable text.

How URL Decode 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
