URL encoding (also called percent encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Special characters, spaces, and non-ASCII characters are converted to a format that can be safely transmitted in URLs. This tool provides bidirectional conversion between plain text and URL-encoded strings, making it essential for web developers, API developers, and anyone working with URLs.

Use Cases

  • Web development: Encode query parameters and URL components for safe transmission
  • API integration: Encode data in API requests and decode responses
  • Form data: Encode form values before submitting to servers
  • Link generation: Create safe URLs with special characters
  • Data parsing: Decode URL-encoded data received from web requests
  • Email links: Encode email addresses and other data in mailto links
  • Social media: Encode URLs for sharing on social platforms
