Frequently Asked Questions
Are my files uploaded?
No. The entire process uses HTML5 APIs to compress the images utilizing your device's own CPU. It is completely offline-capable and highly secure.
Why should I use maximum dimensions?
Sometimes an image taken from a phone is 4000x4000 pixels. Capping the dimension (e.g., 1920px HD) allows the compressor to achieve drastically smaller sizes.
Does it work on Mobile?
Yes, this tool is fully optimized for iOS and Android web browsers.
Why settle for massive image payloads when you can intelligently shrink them with our **Smart Bulk Image Compressor**? CosmoxHub provides unmatched image optimization technology directly embedded in your browser. With advanced WebAssembly techniques, we guarantee your JPG, WebP, and PNG visuals are compressed significantly (often by up to 80%) while maintaining striking visual accuracy.
Security and speed are at the heart of our mission. Unlike older image minification methods that force you to upload precious content to an insecure remote cloud, the **Smart Image Compressor** performs memory-safe compression exclusively on your own desktop or mobile processor. Use the custom MB/KB sliders to meet strict upload size constraints on portals, job applications, or forums with absolute ease, and export dozens of processed results in a neat `.zip` package.
