URL Encoder & Decoder
Percent-encode a query value or a whole URL, and decode it back. Component mode encodes everything reserved; full-URL mode keeps the URL’s structure readable.
Runs 100% in your browser. Encoding and decoding happen on this device, character by character.
Your input never leaves this page — there is no Hermet server to send it to, and nothing you paste is saved anywhere. Reload with your browser’s Network tab open and watch: no request carries your data, because no request is made at all.
