What This Tool Does

Frequently Asked Questions
What is a progressive JPEG?
A progressive JPEG loads in multiple passes — first a low-quality preview of the full image, then progressively sharper versions. This creates a better user experience compared to baseline JPEGs that load top-to-bottom.
Are progressive JPEGs smaller?
Often yes — progressive JPEGs can be 2-10% smaller than equivalent baseline JPEGs, especially for larger images.
