Free Image Tool – Compress, Convert, and Resize with No Uploads·smallimg.cc
SmallImg is a free, browser-based image tool that resizes, compresses, and converts JPG, PNG, WebP, GIF, and AVIF images. All processing happens locally in the browser using Web Workers, Canvas API, and WebAssembly, so images are never uploaded to a server. It supports batch processing, adjustable quality/size settings, and bulk ZIP downloads.
