How does URL encoding work?

URL encoding replaces special characters with percent-encoded equivalents (e.g., spaces become %20). Toollo's tool lets you encode or decode URL strings instantly in your browser for free.

When do I need to URL encode a string?

URL encoding is necessary when passing special characters in query parameters, form data, or API requests. Characters like &, =, spaces, and non-ASCII characters must be encoded to work correctly in URLs.

Does Toollo's URL encoder handle all special characters?

Yes, it handles all reserved and unsafe characters as defined by the RFC 3986 standard. Processing happens entirely in your browser with no data sent to any server.
