Prepare your images
Choose up to 20 images (20 MB each). Compression may change format and image quality.
No images selected
Target KB is a goal, not a guarantee. Complex images, browser encoders and PNG lossless output can exceed it. For best compression, use JPG or WebP. Enlarging pixels will not improve image detail.
