What is URL Encoding and Decoding?
URL encoding, also known as percent encoding, converts special characters in URLs into a format that can be safely transmitted over the internet. Our free online URL encoder and decoder tool helps developers and web professionals encode URLs, query parameters, and URI components instantly.
URL encoding is essential for web development, API integrations, and handling special characters in URLs. Characters like spaces, ampersands, and international characters must be encoded to prevent breaking URL structure. Our tool supports both URI encoding and component encoding methods.
