Usage and safety notes

When to encode a component

Encode a single path segment or parameter value; for example a/b becomes a%2Fb。

Repeated parameters are preserved

Parsing and building preserve repeated parameters in order, such as tag=one&tag=。

Inspect redirect targets

Encoding is not a security check. Verify the scheme and host before opening an untrusted link.

Clean share link

Remove UTM and common ad click IDs and embedded URL credentials while keeping other parameters and fragments. Signed links may stop working after cleaning.
