What is URL encoding?
URL encoding (percent-encoding) converts characters that aren't allowed in URLs — like spaces, & and non-English letters — into % codes (a space becomes %20). This free tool encodes and decodes URLs instantly, right in your browser.
How to use it
- Encode: paste text or a URL with special characters; get the encoded version live as you type.
- Decode: switch modes and paste a %20-style URL to read the original.
When you need it
Encoding matters when building links with query parameters (?q=hello world), handling non-English characters in URLs, or debugging redirect chains. Unencoded special characters break links or get misinterpreted by servers.
Private by design
Everything runs locally. URLs you paste are never uploaded.
Frequently asked questions
Is this URL encoder free?
Yes — free forever, no signup.
What does %20 mean in a URL?
It's an encoded space. URL encoding represents a space as %20, and other special characters get their own % codes.
Why encode URLs at all?
URLs may only contain a limited character set. Spaces, ampersands, question marks and non-ASCII characters must be encoded or the link breaks.
What's the difference between encodeURI and encodeURIComponent?
This tool uses encodeURIComponent, which encodes every special character — the right choice for query values and individual parameters.
Does it handle non-English characters?
Yes — characters are encoded as UTF-8, so Arabic, Chinese, emoji and accented letters all work.
Does it work offline?
Yes, once the page has loaded.
