About this tool
The PixelForge Duplicate Line Remover scans any block of text and removes repeated lines, keeping only the first occurrence of each. It is useful for deduplicating word lists, removing repeated log entries, cleaning up CSV data, and merging lists from multiple sources. Options include case-insensitive matching, trimming whitespace before comparison, and sorting the output after deduplication. All processing is instant and entirely in the browser.
