What is URL Encoding?
URL encoding (also called percent encoding) converts special characters in URLs into a format that can be safely transmitted over the internet. Certain characters have special meanings in URLs and must be encoded to avoid conflicts.
For example, spaces become %20, and ampersands become %26. This ensures that URLs work correctly across all browsers and systems.
