URL Encoder

Encode special characters in URLs for safe use in links and APIs. Free online URL encoder tool.

Everything runs in your browser. Your input is not sent to a server.

How to use the URL Encoder

Paste the string or URL component to encode.
Press Encode.
Copy the percent-encoded result.
Use it in query parameters or path segments as needed.

How it works

Unsafe or reserved characters are replaced with %HH sequences so the value can travel safely in a URL. Spaces often become %20 (or + in some form encodings).

Essential when building query strings and API requests.

Examples

“hello world” → hello%20world
“a&b=c” → encoded so & and = do not break the query structure
Already-safe alphanumeric characters stay unchanged

URL Encoder FAQ

Should I encode a full URL?

Usually you encode components (query values), not the entire URL including https:// and slashes—unless you have a specific nested-encoding need.

Is this the same as Base64?

No. URL encoding uses percent-sequences for URL safety; Base64 is a different alphabet for binary data.

Is the URL Encoder free?

Yes.
