URL Encoder Decoder is a free online tool that converts unsafe URL characters into encoded format and decodes encoded URLs back into readable text. It is useful for developers, marketers, SEO specialists, testers, and anyone working with web links.
URL encoding, also known as percent encoding, converts special characters into a format that can be safely transmitted in URLs. For example, spaces may become %20, and special symbols can be represented using encoded sequences.
