One recommendation for this tool
I would consider renaming the page title from “Remove Duplicates” to “Remove Duplicate Lines” if the tool only removes duplicate lines rather than duplicate words, sentences or paragraphs. It’s much clearer for users and targets a more specific search intent. If you plan to expand the tool later to support duplicate words or paragraphs, then keeping the broader name “Remove Duplicates” is the better long-term choice.
