Clean URLs

2 tracking parameters removed

Use this utility only with data and systems you are authorized to assess. Formatting a URL list does not grant permission to test its destinations.

Six output formats from one URL list

Switch the workspace output without editing your input. Every format is normalized and deduplicated automatically.

Clean URLs

Lowercase schemes and hostnames, sorted query strings, no fragments, credentials or repeated lines.

Domains

Collapse a mixed list into a unique hostname inventory, ready for scope reviews and asset lists.

Endpoints

Keep origin and path, drop every query string, so the same endpoint is only listed once.

Paths

Extract route structures across hosts to compare environments or map an application surface.

Parameters

Turn a URL list into a deduplicated query key wordlist without writing a single regular expression.

FUZZ templates

Swap every parameter value for the FUZZ placeholder used by common authorized testing workflows.

Private by design

A URL utility that never sees your list

No account, no upload and no request to the domains you paste—only text processing in your own browser tab.

100%

Local processing

Every URL is parsed by your browser. Nothing is uploaded to DorkPlus and no pasted domain is contacted.

How to deduplicate a URL list

Standardize superficial URL differences first, then return each remaining normalized address exactly once.

01

Paste the complete list

Add repeated URLs one per line or paste text containing links. The workspace counts valid, invalid and duplicate outputs.

https://example.com/?b=2&a=1 https://EXAMPLE.com/?a=1&b=2
02

Set the comparison rules

Choose whether tracking keys, fragments, credentials and trailing slashes should be removed before URLs are compared.

03

Review the unique output

Exact normalized matches collapse to one line. The duplicate counter shows how many repeated output lines were removed.

https://example.com/?a=1&b=2
04

Copy or export the list

Download the deduplicated URLs as text or copy them into the next authorized workflow.

Why it matters

Why normalize before removing duplicates?

String-only deduplication misses URLs that differ in hostname capitalization, parameter order or removable campaign tags. Normalization exposes those equivalent representations before comparison.

Two URLs are not guaranteed to serve the same response merely because they look similar. The optional controls let you choose the definition of a duplicate that fits your dataset.

  • Count removed duplicate outputs
  • Control normalization before comparison
  • Preserve one stable URL per exact result

Common use cases

Crawler exports

Reduce repeat URLs before a second processing pass.

Content inventories

Remove formatting variants from a page list.

Redirect migrations

Prepare stable old and new URL sets for comparison.

Research datasets

Save one normalized copy of each collected link.
