URL component encoding keeps a value from being mistaken for URL syntax when placed in a query or path segment.

Good to know

Frequently asked questions

Does this encode a complete URL?

It encodes the full input as one URL component. Use it for query values or path segments; it does not parse a URL into separate parts.

What happens to plus signs?

Plus signs are encoded as %2B so they remain literal plus signs when decoded.

Why did decoding fail?

The input may contain an incomplete percent escape such as %2. Check that every percent sign is followed by two hexadecimal characters.
