    What is Bulk image compression and what is it for?

    Shrinks several images at once, converts them to WebP and scales them to the width you want; the result downloads as a ZIP. More than half of a website's weight usually comes from images, so this is the step with the fastest return on page speed.

    Frequently Asked Questions
