One install, every conversion category
File Converter Pro covers six format families with a single Windows 10 / 11 desktop app: image, PDF, document, data, video and audio. The same drag-and-drop queue handles a folder of 4 GB MKV files and a batch of 32 KB ICO icons in identical UI flow. Settings persist per category, so you can switch between encoding tasks without rebuilding configurations every time.
Web converters force you to pick a single tool per format — and each one has its own upload limit, watermark policy, daily quota and login flow. A desktop app collapses that surface into one workflow: pick a folder, pick a target format, click Convert. Nothing uploads. Nothing watermarks. Nothing caps.
