DiffMill

This Windows desktop application compares Word, Excel, PDF, text, code, and image files locally, revealing edits through plain-text diffs, Word-style redlines, spreadsheet grids, OCR for scanned PDFs, and pixel-accurate image views. It helps people review revisions, spot missing or changed content, and protect sensitive documents without uploading them to the cloud, making it useful for writers, editors, developers, analysts, and anyone managing document workflows.
