URL Encoder / Decoder
Encode or decode URL components using encodeURIComponent / decodeURIComponent.
What is the URL Encoder / Decoder?
A URL encoder converts characters that are not allowed or have special meaning in a URL — spaces, ampersands, question marks and so on — into a safe percent-encoded form, and decodes them back again. It is essential when building links with query parameters or reading encoded URLs. This tool uses the same encoding the browser does (encodeURIComponent / decodeURIComponent), so results match what your code and browser expect. It runs locally and needs no account.
How to use the URL Encoder / Decoder
- Paste the text or URL component.
- Choose Encode or Decode.
- Copy the converted value.

Frequently asked questions
What does URL encoding do?
It replaces unsafe characters with a percent sign followed by a code, so the URL stays valid — a space becomes %20, for example.
When do I need to encode a URL?
Whenever you put text with spaces or special characters into a query parameter or path segment.
Does it encode the whole URL or just parts?
It encodes components, like a single query value, which is what you usually want rather than mangling the whole address.
Is it free?
Yes, free with no sign-up.
