How does image compression work?

We use smart lossy compression techniques to reduce the file size of your JPEG and PNG images. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data with almost no visible difference.

What is the best format for web images?

WebP is generally the best format for web images as it offers superior compression (typically 26% smaller than PNGs and 25-34% smaller than JPEGs) whilst maintaining high quality.

Lossy compression (like JPEG/WebP) removes some data to reduce size, which can slightly affect quality. However, at 80% quality, the difference is usually indistinguishable to the human eye.

PNG is a lossless format. To significantly reduce file size, it's recommended to convert PNG to WebP or JPEG using the "Output Format" option.
