URL Encoder

About this tool

Percent-encode text so it can be used safely inside a URL, for example as a query string value. It applies JavaScript's encodeURIComponent: letters, digits and the characters - _ . ! ~ * ' ( ) stay as they are, and everything else, including spaces and non-ASCII letters, becomes %XX using UTF-8. Encoding runs in your browser as you type. Because it encodes slashes, colons and question marks too, it is meant for individual values, not whole URLs.

How to use it

1. Paste the text or value to encode.
2. Copy the encoded result.
3. Insert it into your URL, for example after ?q=.

Example

hello world&x=1/é

hello%20world%26x%3D1%2F%C3%A9

Common problems

Whole URL no longer works

Characters such as : / ? & = are encoded too, so https://example.com/a b becomes https%3A%2F%2Fexample.com%2Fa%20b. Encode only the parts that need it, such as a query value.

Spaces appear as %20, not +

This tool uses %20. Most servers accept it in query strings, but form-style encoding uses +.

Result gets encoded twice

Encoding already-encoded text turns % into %25. Encode raw text only once.
