URL Encoder / Decoder

URL encoding, also known as percent-encoding, is a process used to convert special characters and non-ASCII characters into a format that is safe for transmitting over the internet. URLs (Uniform Resource Locators) are web addresses that contain specific characters, and not all characters are allowed in a URL.

URL encoding replaces non-alphanumeric characters with a "%" followed by two hexadecimal digits. For example, the space character " " is encoded as "%20". This encoding ensures that URLs are properly formatted and can be understood by web servers and browsers.

URL decoding, on the other hand, is the reverse process of URL encoding. It involves converting the encoded characters back to their original form. For example, "%20" would be decoded as a space character.

URL encoding and decoding are commonly used in various scenarios, such as:

Handling query parameters: When passing data via a URL's query parameters, special characters and spaces need to be encoded to ensure they are correctly interpreted by the receiving server.

Form submission: When submitting form data through HTML forms, the data is URL-encoded before being sent to the server.

URL construction: When constructing dynamic URLs programmatically, URL encoding is necessary to handle any special characters that may be included in the data.

There are online tools and programming libraries available that provide URL encoding and decoding functionality, allowing you to encode or decode URLs easily
