AliExpress shoppers scroll an endless grid of near-identical products at thumbnail speed, and the listings whose photos paint first are the ones that get the tap. Sellers load dozens of detail shots, size charts, and colour variants per item, and camera-original files turn that into a slow, heavy page for buyers on mobile data across every timezone. Skwish compresses images locally in your browser with a live before/after readout per file, so every variant and close-up stays crisp while the file drops to a fraction of its size. Compress a whole product set in one batch and export a ZIP. Nothing leaves your device.
