What is the difference between the two scopes?

Component also escapes & = ? / : and suits a parameter value; Full URL keeps those and only escapes spaces, Unicode, etc., for a complete link.

Why does decoding fail?

The text contains a malformed % escape (for example a lone %). Check that it was copied in full.

Are my files or data uploaded?

No. Everything runs locally in your browser with no network upload, and is discarded when you close the page.

Do I need to sign up or pay?

No. The site is completely free, needs no account and has no usage limits.

🔗URL Encode & Decode - Online URL Encoder / Decoder

Percent-encode and decode URLs or query parameters. Two scopes: Component encodes delimiters like & = ? / (for a single value), while Full URL keeps those structural characters (for a whole link). Chinese, spaces and symbols are escaped correctly.
