Dynamically Compress Images & Adjust Quality

Web sites and applications need images both to look great and display quickly. Perfectly balance image quality against image size on any JPG or WEBP file. For even smaller downloads, Filestack can also losslessly compress JPGs or PNGs with the highly-optimzed mozjpeg compression algorithm. (If the image has already been compressed, the API is intelligent enough to skip this step and not re-apply compression.)

XS to XL, responsive Images made entirely automatic

Website speed is critically important—especially for mobile users. One of the best techniques to improve the performance of your website and applications is to create responsive image sets—serving the exact amount of pixels for each different device. Rather than scaling a large image down (and wasting bandwidth), you can use Filestack to instantly and automatically generate a new version of the image at the perfect size.
