URL Builder

What is URL Builder?

A URL builder is a tool that helps you construct Uniform Resource Locators (URLs) by combining different components like the protocol scheme, domain name, path, query parameters, and fragment identifiers. Unlike manually typing URLs, a URL builder ensures proper encoding of special characters and validates the URL structure according to web standards.

Common Use Cases

• API endpoint testing and development - quickly construct URLs with multiple query parameters
• Deep linking for mobile apps - create custom URL schemes with parameters
• Web development - build URLs for pagination, filtering, and search functionality
• Email marketing - construct tracking URLs with UTM parameters
• Testing redirect chains - build URLs to test HTTP redirects
• Social media sharing - create shareable URLs with pre-filled parameters

How It Works

The URL builder allows you to input each component of a URL separately: the scheme (http, https, etc.), hostname, optional port, path, query parameters as key-value pairs, and fragment. The tool automatically percent-encodes special characters in query parameters and paths according to RFC 3986 standards. It validates the URL structure and provides a real-time preview of the final URL that you can copy and use.

Examples

Scheme: https, Host: api.example.com, Path: /users, Query: page=1&limit=10&sort=name

https://api.example.com/users?page=1&limit=10&sort=name

Scheme: https, Host: app.example.com, Path: /product, Fragment: details

https://app.example.com/product#details
