Frequently Asked Questions
No. URL encoding and decoding happen entirely in your browser. Nothing you enter is uploaded or stored.
URL encoding (percent-encoding) replaces characters that are unsafe in a URL — like spaces and symbols — with a percent sign followed by their hex value, so the URL stays valid.
Encoding a component escapes characters like & and = that are meaningful in a full URL, so use component encoding for query values and full-URL encoding for whole addresses.
