FAQs

What's the difference between "Keep First" and "Keep Last"?

"Keep First" preserves the first occurrence of each line. "Keep Last" keeps the last occurrence instead.

What does "Show Counts" do?

Adds counts to each line showing how many times it appeared: "apple (x3)". Helps identify most common duplicates.

Does it work with partial duplicates?

No, it removes exact line duplicates only. For partial duplicates, use our "Text Comparison" tool (coming soon).

Can I see which lines were removed?

Yes! Use "Highlight Duplicates" to see analysis. The "Duplicate List" section shows all found duplicates.
