Compress OpenCart product images before you upload to image/catalog
OpenCart stores originals in image/catalog and only generates the smaller cache sizes. The original stays on disk and in the page weight. Compress the set locally first and every cached size, every grid tile, and every product page ships a lighter file without extra extensions.
