Frequently asked questions
What is URL encoding used for?
URL encoding (percent-encoding) is used to safely transmit special characters in URLs, query parameters and API requests.
Does it encode the entire URL or just the parameters?
The tool encodes the exact text you provide. It is best used for encoding query parameter values rather than the base URL structure.
