Duplicate Remover

Paste or drop a list of URLs, domains, or keywords. Remove duplicates locally — prefix/field match, optional fuzzy near-dupes, two-list compare, and download TXT/CSV/JSON. No signup, no upload, no daily limit.

Mode

Input list (one item per line) Choose .txt / .csv or drop a file below

Trim whitespace Case-insensitive Drop blank lines SEO URL / domain normalize

Keep Sort

Match mode

When prefix or field match is on, exact full-line match is replaced by that keying strategy.

Near-duplicate (fuzzy) match

Similarity threshold

Fuzzy uses Levenshtein similarity locally after exact keying. Large lists are expensive (O(n²)).

Output

Line numbers Annotate duplicate frequency

Option presets

SEO normalize strips protocol, leading www, trailing slash, and lowercases the host so URL variants collapse to one line.
