Percent-encode text so it can be dropped safely into a URL or a query string. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.
How to do it
- Paste the text or value you need to put in a URL.
- Read the encoded version.
- Press Copy and paste it into your link.
Questions
What is percent encoding?
URLs can only contain a restricted set of characters. Everything else — spaces, accents, ampersands, anything non-English — has to be written as % followed by its byte values. café becomes caf%C3%A9.
Should I encode the whole URL or just part of it?
Just the part you are inserting — a query value, a path segment, a search term. Encoding a whole URL would escape the :// and the slashes that make it a URL.
Why does this encode more characters than some other tools?
Characters like !, ', ( and * are legal in a URL but not safe in every position. Encoding them is the conservative choice and never changes the meaning.
