What is URL encoding?

URL encoding (percent-encoding) replaces unsafe characters in a URL with a percent sign followed by two hexadecimal digits. For example, a space becomes %20.

When should I URL-encode a string?

You should URL-encode strings when passing them as query parameters, form data, or any part of a URL that may contain special characters like &, =, or spaces.

Does this tool handle Unicode characters?

Yes. encodeURIComponent converts Unicode characters to their UTF-8 percent-encoded representation.

Is my data processed on a server?

No. All encoding and decoding runs entirely in your browser. Nothing is sent to any server.
