About the Duplicate URL Remover

Duplicate URL Remover strips repeated addresses out of a list. Plain deduplication is the easy part. The useful part is deciding what counts as the same URL, because the same page routinely appears in a list five times wearing slightly different clothes.

Switches let you ignore the differences that usually do not matter: http against https, a www prefix or none, a trailing slash or none, letter case in the domain, a fragment on the end, and tracking parameters such as utm_source. With those enabled, five variants of one page collapse into a single entry.

The first form of each address is what survives, so the list keeps the version you actually wrote, and a summary reports how many rows went in, how many unique addresses came out, and how many duplicates were removed.

Frequently asked questions

Why would the same page appear several times in my list?

Because a URL has many equivalent spellings. Add or drop a trailing slash, switch http for https, add www, append a campaign parameter, and you have five strings that all load one page. Tools that compare raw text treat them as five pages.

Which tracking parameters are removed?

The common campaign and click identifiers, including the utm family, gclid, fbclid, msclkid and a few others. Removal is only for comparison; the surviving URL keeps whatever you wrote unless you ask for the cleaned form.

Does ignoring the fragment matter?

Often yes. The part after a hash is handled in the browser and never sent to the server, so two URLs differing only by fragment are usually the same page as far as a crawler is concerned.

Is a trailing slash really the same URL?

Technically it can differ, and a badly configured server can serve different content for each. In practice almost every site treats them as one page and redirects between them, which is why ignoring the difference is the sensible default.

Which copy is kept?

The first one in your list, in its original form, so order and spelling are preserved.

Is there a size limit?

No. Lists of hundreds of thousands of rows deduplicate quickly, because the work happens in your browser.
