About URL Encoder / Decoder

Wondering what and when to use URL encoders and decoders? For better understanding let's start this from URL. URL is known as uniform resource locator is the web address of a website or a webpage. URL can either be as names (ex: https://seo-tools.mixtart.com/) or as an IP address (123.456.7890). Names are easier so we usually use the name to browse the website. Here in find DNS records tool page you'll find detailed explanation of how domain name works and how your web browser connects with the web server and displays the webpage. Your web browser requests web pages from servers using URL.

What is URL encoding or Percent-encoding?

URL encoding or percent encoding is a mechanism of encoding text or information in Uniform Resource Identifier. This is done to convert any special characters in URL to standard URL format so that it can be transmitted through internet. Your website's URL must follow certain standards in order to be SEO and user friendly such as keeping it short, using keywords and removing special characters. Apart from this there are certain URL rules which is specified by RFC 1738 for worldwide interoperability.  By encoding URIs uniformly according to international standards their value will not be misinterpreted and there won't be any confusion transmitting data over the internet.

According to internet standards of URL specification an URL can only contain certain set of characters that is ASCII character sets. If the URL contains non ASCII characters then it has to be converted to standard ASCII format and this is where URL encoding or percent encoding comes in. URL containing non ASCII characters will be replaced by "%" along with two hexadecimal digits. This encoding system is not just for URLs (Uniform resource locators) but it also applies to URIs (Uniform Resource Identifiers) and URNs (Uniform Resource Names). So rather than calling it as URL encoding, the term percent-encoding should be the preferred way.
