Free Image Compressor
Compress images automatically in the browser. Drop files, compare before and after, adjust quality, and save optimized results without uploading originals.
A free image compressor reduces image file size - JPEG, PNG, or WebP - so web pages load faster, storage shrinks, and image-heavy galleries publish without lag. This tool compresses in your browser with Canvas (no uploads), batches up to 20 files, and shows a before/after comparison so you control the quality-vs-size trade-off. Optimized files then flow into CyberStock for buyer-data keywording from 50M+ real searches.
