URL Encoder/Decoder

Easily encode or decode URLs to handle spaces, symbols, and special characters in web links and parameters.

The URL Encoder / Decoder tool allows you to safely convert text into a format that can be transmitted over the internet. URLs can only be sent over the web using a limited set of ASCII characters, which means any spaces, symbols, or special characters must be encoded into a compatible format. This process is known as percent-encoding, where unsafe characters are replaced with a "%" followed by their hexadecimal value.

For example, a space is encoded as %20, while characters like "&", "=", and "?" are encoded to prevent them from interfering with query parameters in a URL. Without proper encoding, URLs can break, data can be misinterpreted, or requests may fail entirely—especially when working with APIs, form submissions, or dynamic links.

This tool is useful in a wide range of development scenarios. You can use it to encode query string values before sending them in HTTP requests, sanitize user input for URLs, or debug issues where encoded values appear unreadable. On the other hand, decoding helps convert encoded URLs back into a human-readable format, making it easier to understand parameters, troubleshoot bugs, and inspect data being passed between systems.

Whether you're building web applications, integrating third-party APIs, or simply testing URL behavior, this tool provides a fast and reliable way to encode and decode data without relying on external libraries or browser console commands. It’s especially helpful for frontend developers, backend engineers, and QA testers who frequently work with dynamic URLs and need quick, accurate results.
