  🚀 Instant & Cursor-Driven
  No clunky UI to navigate. The conversion wheel appears exactly where your mouse is. Only compatible formats for your dragged files will show up.

✨ Core Features

• The Smart Format Donut: Hold your designated hotkey and drag a file. NextFilee analyzes the file header and instantly displays a radial menu of conversion options.
• Batch Processing on Steroids: Drag 50 images at once. NextFilee utilizes multi-threading to convert them all in parallel, saving the results right next to the originals.
• Watch Folders: Set a specific directory (e.g., your Downloads folder). NextFilee will silently monitor it and auto-convert specific incoming files (like .heic to .jpg) instantly.
• Advanced Tuning: Press Tab or scroll the mouse wheel while the donut is open to flip it. Access advanced settings like PDF compression levels, video bitrates, or image DPI.
• Browser Drag & Drop: Drag an image directly from Chrome, Edge, or Firefox into the NextFilee drop zone. It downloads and converts in one seamless motion.
