Optimizilla
Optimizilla is a web-based image optimization tool that employs an effective combination of top-tier optimization techniques and lossy compression methods to reduce the file sizes of JPEG, GIF, and PNG images to their smallest viable dimensions while maintaining acceptable quality. Users have the convenience of uploading up to 20 images at once, and the platform cleverly assesses these images, minimizing their file sizes without compromising overall visual integrity.

Once users are content with the adjustments, they have the option to download the compressed images either as a single ZIP file or one by one.
