Full URL Encoding (encodeURI)

Encodes special characters but preserves the URL structure. Characters like /, :, ?, # are not encoded.

Use for: Complete URLs that you want to encode while maintaining their structure.

Component Encoding (encodeURIComponent)

Encodes all special characters including /, :, ?, #, etc. This is more aggressive encoding.

Use for: Query parameters, fragments, path segments, or any component of a URL.

Common Use Cases

• Encoding query parameters in API requests
• Preparing URLs for HTTP requests
• Storing URLs in databases or configuration files
• Debugging URL-related issues
• Processing user input that will be used in URLs
