Why encoding and decoding URLs ?

URL encoding is essential because certain characters in a URL have special meanings or may not be supported in all contexts.

• Preserving Data Integrity:
  Characters like spaces, &, ?, =, or # need to be encoded to avoid misinterpretation by web servers or browsers. For instance, a space in a URL is replaced with %20.
• Ensuring Safe Transmission:
  Encoding makes URLs safe to use across the web, in emails, or within APIs without corrupting the data or causing errors.
• Complying with URL Standards:
  URLs must adhere to the format specified by the standards (RFC 3986). Encoding ensures compliance, making URLs universally readable.

URL decoding is equally important to interpret and process encoded data accurately.

• Reading Human-Friendly Data:
  Encoded URLs are difficult to read. Decoding converts %20 back to a space, or %3D back to = for better understanding.
• Processing User Input:
  When URLs or query parameters are encoded during transmission, decoding restores the original data, such as names or search terms.
• Debugging and Analysis:
  Developers and analysts often need decoded URLs to understand or troubleshoot how data is passed in applications or APIs.

What is the URL encoder and decoder and how it works ?

The URL encoder converts characters in a URL into a format that is safe for transmission over the internet.
It replaces special characters (such as spaces, &, and =) with percent-encoded representations (e.g., %20 for a space).
This process ensures the URL is properly interpreted by web servers and browsers, preserving the integrity of data included in query strings, form submissions, or API requests.
The URL decoder reverses URL encoding by converting percent-encoded characters back into their original form. For example, it translates %20 back into a space.
URL decoders are essential for interpreting and processing data embedded in URLs, such as query parameters or encoded user input, to make the information readable and usable.
The data are processed on the fly and we don't store any data on our servers.
