Redfin puts the photo first: tap the listing, the gallery fills the screen. That first impression is a load-speed test as much as a taste test. Straight-from-camera real-estate photos are heavy enough that a full listing can take seconds to paint, and seconds is where buyers leave. Skwish compresses images in your browser with a live before/after size readout, so you keep a sharp, honest photo of every room while the file falls to a fraction of its weight. Compress a full gallery in one batch and export a ZIP. Nothing is uploaded to a server.
