URLs from a crawler, analytics and a sitemap never match. Normalise them all to one format and every comparison starts working.
The example below is already loaded, so you can see exactly what you get. Replace it with your own list and the result updates as you type.
🔗 Doing the whole job? Clean a URL list → every fix for it, ticked and in the right orderGot a bigger job? The full Notepad runs the same engine on lists of any size — chain this with dedupe, sort and filter, undo any step, and save the whole routine as a recipe for next time.
HTTP://WWW.Example.com//Blog//Post
example.com/shoeshttps://example.com/Blog/Post
https://example.com/shoesSettings used: www.: Remove www.
Makes URLs consistent so duplicates can be found: lowercases the domain, adds or removes www, forces https, collapses double slashes and optionally lowercases the path.
Gives a messy list of URLs one consistent format: adds https:// where the scheme is missing or http, lowercases the host, adds or removes www. as you choose, and collapses doubled slashes in the path. Lowercasing the path is optional because paths can be case-sensitive.
Normalising first is what makes Remove Duplicates and list comparisons work on URLs from different sources.
Yes. Normalise URLs runs entirely in your browser, on this page and in the full Notepad, with no sign-up, no limits, and nothing sent to a server.
No, it only rewrites the text. Nothing is fetched.
Only if your server treats paths case-insensitively. Otherwise /Blog/ and /blog/ can be different pages.
Links scraped from HTML come as /about and ../shop/. Turn them into full, crawlable URLs in one click.
Backlink exports list every linking page; you need the linking domains. Paste the URLs and get clean domains …
Get clickable homepage URLs from any list of deep links — the protocol and domain stay, everything after goes.
Tracking tags turn one page into fifty “different” URLs. Strip everything after the ? and they collapse back …
