Is the comparison case-sensitive?

By default yes — 'Apple' and 'apple' are treated as different lines. A case-insensitive option is also available.

Does it remove blank lines too?

Blank lines are treated as duplicates if they appear more than once and can be removed along with other duplicates.

The tool handles thousands of lines without slowdown — suitable for large log files and keyword lists.
