About URL Encoder & Decoder

URL encoding (also called percent-encoding) converts characters into a format that can be safely transmitted over the internet. This tool helps you encode text for URLs or decode URL-encoded strings.

Key Features

• Bidirectional Conversion: Encode to URL format or decode URL strings
• Component vs Full URL: Choose between encoding URL components or full URLs
• Real-time Conversion: Instant results as you type
• Copy to Clipboard: One-click copying of encoded/decoded output
• UTF-8 Support: Handles all Unicode characters
• No Data Storage: All processing happens locally in your browser

Common Use Cases

• Encode query parameters for URLs
• Decode URL parameters from browser address bar
• Prepare form data for HTTP requests
• Debug API endpoint URLs
• Encode special characters in URLs

Encoding Types

Component Encoding (encodeURIComponent):

• Encodes all special characters except: A-Z a-z 0-9 - _ . ! ~ * ' ( )
• Use for encoding values in query strings and path segments
• Example: hello world → hello%20world

Full URL Encoding (encodeURI):

• Preserves URL structure characters: : / ? # [ ] @ ! $ & ' ( ) * + , ; =
• Use for encoding complete URLs
• Example: https://example.com/path?q=hello world → https://example.com/path?q=hello%20world

FAQ

What’s the difference between component and full URL encoding? Component encoding is stricter and encodes more characters. Use it for query parameters. Full URL encoding preserves URL structure.

Why do I see %20 instead of + for spaces? Both are valid, but %20 is the standard percent-encoding format. The + is specific to application/x-www-form-urlencoded format.

Is URL encoding secure? URL encoding is for data formatting, not security. It doesn’t encrypt or hide data. Don’t use it for sensitive information.
