File Converter Pro is a free, fully offline Windows desktop application that converts documents, images, audio, and video, all from one polished tool, without a browser or uploading your files anywhere.

Built with Python and PySide6. Animated startup, system-aware dark/light theme, statistics dashboard, gamified achievements, multi-language support. Lightweight: ~250 MB as an exe, ~125 MB from source.

Core philosophy: ship nothing until it runs perfectly on a clean machine, with zero preinstalled dependencies.

• All-in-one: documents, images, audio, video, batch supported
• 100% offline & private: no telemetry, no uploads, no internet required
• Statistics & achievements: animated dashboard and SQLite-backed gamification
• Automation: watch folders and scheduled tasks, runs as a background daemon
• Windows context menu: right-click any supported file → Convert with FCP
• Community i18n: drop a .lang JSON file to add a language, no code needed
