Using this site with the just the Address Bar:
You can add any link you want cleaned after baptize.link/ and it will open this page with the link already cleaned.
baptize.link/https://example.com/page?utm_source=…
If you put a # in between baptize.link and the link you want cleaned you'll avoid using the server (uses the browser stored version of this page).
