Legacy File Converter

Legacy File Converter is a Windows desktop app that batch-converts old and proprietary file formats — WordPerfect, Lotus 1-2-3, Quattro Pro, legacy Microsoft Office, HEIC images, and more — into modern formats such as DOCX, XLSX, PPTX, PDF, PNG, JPG, HTML, and Markdown. It runs fully offline using bundled LibreOffice and ImageMagick engines, supports batch and folder conversion, and can look inside archives.
