URL extractor

Paste text with links in it and they're listed on the right, once each. Links starting www. count too, unless you tell it to skip them.

Tracking tags strips utm_source, fbclid, gclid and the other parameters that only exist to track a click, and keeps the ones the page needs, like an id. The page opens with it on. List switches to Sites only for one line per website.

Nothing is visited or checked, and nothing you paste leaves your browser.

The hard part of extracting links is knowing when to stop. A sentence that ends with a link ends with a full stop, and the full stop isn't part of the address. Plenty of extractors keep it, and the link then fails.

Brackets are harder. Wikipedia's page on the planet Mercury is at /wiki/Mercury_(planet), so a closing bracket can belong to the link. But a link written in brackets in a sentence ends with one that doesn't. This tool keeps a closing bracket only when the link opened one.

It also never changes the case of a link. Domains don't care, but the part after them can, and /ReadMe.PDF and /readme.pdf can be different files.

Take this: New post (see https://example.com/blog/post-1?utm_source=newsletter&utm_medium=email). Older ones: www.example.com/archive#2025, and https://shop.example.org/item?id=42&gclid=Cj0K. Same post again: https://example.com/blog/post-1?utm_source=x

With tracking tags kept, four links come out. The first loses the closing bracket and full stop after it, the second loses its comma, and the third its full stop. The last is listed separately, because its utm_source differs.

Strip the tracking tags and it's three. Both utm_ tags go from the first link, which leaves it identical to the last, so it's listed once. The shop link keeps id=42, which picks the item, and loses gclid. The #2025 on the archive link stays. Switch List to Sites only and it's two lines: example.com and shop.example.org.

The email extractor does the same for email addresses. If a link comes out full of %20 and %2F, the URL decoder turns it back into readable text.
