Convert images, data files and documents straight from your terminal: PNG, JPG, WebP, AVIF, BMP, TIFF and GIF for images; JSON, CSV and XML for data; plus clean Markdown→HTML and HTML→text for documents. Convert a single file or entire folder trees — FileFlow Pro preserves your subfolder structure, keeps aspect ratios, never upscales and prints a clear summary with savings. Built for developers and content teams who batch-process files daily, with zero telemetry and no uploads: everything runs locally on your machine.
