About this tool
Percent-encode text for a URL. Choose component, full-URI or form encoding depending on where the value is going.
When you would use it
- Encoding a query parameter
- Building a URL that carries user input
- Preparing a form body
Worked example
name=Ada Lovelace&city=London
name%3DAda%20Lovelace%26city%3DLondon
Things worth knowing
- Component mode is the safe default for a single value inside a query string.
- Encoding works on UTF-8 bytes, so non-ASCII text produces correct multi-byte sequences.
Questions
Frequently asked
When should I use form mode?
When building an
application/x-www-form-urlencoded request body, where spaces are conventionally + rather than %20.Is my data uploaded anywhere?
No. Every tool on JSONWorks runs entirely in your browser using JavaScript. Your input is never sent to a server, never logged and never stored. The simplest proof is to disconnect from the internet — the tools keep working. The site does load Google Fonts and a Google Analytics page-view tag, so you will see those two requests in your network tab, but neither receives anything you type or paste.
