FeatherFile is a browser-based tool that compresses and converts image and PDF files (JPEG, PNG, PDF, WebP, AVIF) entirely client-side using WebAssembly, so files never leave the user's device. It offers drag-and-drop compression with adjustable quality, resizing, and format conversion, plus bulk processing of multiple files.
