ImgMin Pro

ImgMin Pro is a fast, privacy-first web application for batch image compression and format conversion that runs 100% locally inside your browser. Using modern HTML5 Canvas and WebAssembly codecs, it compresses and converts JPG, PNG, WebP, and AVIF images without ever uploading files to an external server. Users can process up to 20 high-resolution images (up to 25 MB each) simultaneously, dial in an exact target file size in KB (such as under 100 KB or 200 KB for web forms and portals), compare before-and-after visual quality with an interactive split-screen slider, resize dimensions proportionally, and export all optimized assets as a single ZIP archive.
