A duplicate URL remover keeps the first copy of each address and drops the rest. You use it when a crawl, export, or sheet has the same page more than once.

Why you need a duplicate URL remover

The same URL arrives in different clothes: a trailing slash, a capital letter in the host, a tracking query, a www. If you treat every string as unique, you count one page three times and you paste the same link twice. Cleaning the list first is cheaper than fixing it on a live page.

This page only dedupes. It does not rewrite the line it keeps. The first original string stays as you pasted it.

Who this tool is for

SEOs use it on crawler exports and broken-link sheets. Editors use it when sources were copied from more than one doc. Affiliates use it when two networks list the same landing page. Analysts use it before they count “unique URLs” in a report.

How to use this tool

  1. Paste one URL per line on the left. Blank lines are ignored.
  2. Leave Ignore case and Ignore trailing slash on unless you need those differences to count as two pages.
  3. Turn on Ignore www when apex and www are the same site for your job.
  4. Turn on Ignore query or Ignore hash when campaign parameters or in-page jumps are not real duplicates you want to keep.
  5. Click Remove duplicates. Copy the unique list. The count shows how many lines stayed and how many were dropped.

How this fits SEO and marketing work

Duplicate hrefs on one page look sloppy and they waste crawl and reporting time. A unique list is what you want before you write anchors, before you submit a sitemap, and before you upload destinations to an ads account. Search Console and crawlers will still show their own duplicate clusters. This tool only cleans the list in front of you.

Do not ignore query strings if those parameters change the content. A filter URL can be a different page. Ignore query when the extra keys are only utm or click ids.

Other tools people use around this job

Deduping does not replace a crawler, a spreadsheet, or Search Console’s page indexing report. Those tools find duplicates on the web. This page finds duplicates in the text you pasted. After the list is unique, people usually sort it, check status codes, or turn the lines into links in their CMS.

Frequently asked questions

It takes a list of URLs and keeps each address once. Extra copies are dropped so you can publish or crawl a clean list.

Exports, crawls, and spreadsheets repeat the same page. Duplicates waste time, inflate link counts, and make you add the same href twice.

SEOs cleaning crawl or export lists, editors preparing source lists, and marketers who merged several campaigns into one sheet.

Paste one URL per line. Choose whether to ignore case, trailing slashes, www, query, or hash. Click Remove duplicates, then Copy.

The first one in the list. Later lines that match under your options are removed.

If you ignore case, yes for the host text. Scheme is still compared. Turn on ignore www to treat www and the apex as the same host.

Yes. Ignore query treats /page?a=1 and /page?a=2 as the same path. Ignore hash drops #section. Use those when tracking parameters are the only difference.

It is free. Deduping runs in the browser. The list is not sent to a server.

No. Options only decide what counts as a match. The line you keep is the original text of the first copy.

Empty lines are ignored. They do not appear in the output.
