Is Tunable Image Block safe?

Clean risk

Tunable Image Block redirects quality-limited image requests through wsrv.nl with the original image URL in the query string.

When quality limit mode is enabled for a site, Tunable Image Block rewrites image requests so wsrv.nl receives and processes the original image URL. The extension applies this through browser request rules for configured sites, while its byte-limit mode only changes the Range header.
