Compress JPG and WebP
Each format uses the best compression method automatically.
JPG Image Compressor
JPG is the most common photo format. Our compressor adjusts quality using a canvas-based re-encoder. Image dimensions never change. Ideal for product photos, blog images, and social media.
WebP Compressor
WebP is 25–35% smaller than JPG at the same visible quality. Supported in all modern browsers. The compressor applies quality optimization while keeping transparency intact.
