Deduplicate huge URL lists instantly. IndexVero can ignore case, www, and trailing slashes so near-identical links collapse into one — cleaning your list before it wastes credits or clutters a report.
How it works
Paste your URLs
Drop in a list that may contain repeated or near-identical links.
Set normalization
Choose whether to ignore case, www, and trailing slashes when deciding what counts as a duplicate.
Copy the unique list
The deduplicated list appears instantly with a duplicate count. Copy all or download as TXT.
Features
Smart duplicate matching
Treat http/https, www, casing, and trailing-slash variants as the same link so true duplicates are actually removed.
Keeps original order
The first occurrence of each URL is kept in place, so your list stays in the order you pasted it.
Instant, private & exportable
Deduplication runs live in your browser on lists of any size, and you can copy or download the clean result.
FAQ
How does duplicate detection work?
Each line is normalized using your chosen rules (case, www, trailing slash) and the first occurrence of each normalized key is kept; later repeats are removed.
Will it treat www and non-www as duplicates?
If you enable “Ignore www”, then example.com/page and www.example.com/page are treated as the same URL and collapsed to one.
Does it keep the original order?
Yes. The tool preserves the order of first appearance, so your list structure is maintained after dedup.
How big a list can I dedupe?
Because it runs live in your browser, you can deduplicate very large lists instantly without waiting on a server job.
