Our marketing emails often include images—headers, product photos, and promo banners. But image size directly affects email load time and deliverability.

I used to ask designers to re-export smaller versions. Now I just drop them into ImgZipper, use the live compression slider, and optimize them down from 800 KB to 120 KB without losing visual appeal.

I can see exactly when the image starts to blur and stop right there. This “control with confidence” wasn’t possible before.

Hot tip: For emails, keep each image under 150 KB for best performance across mobile clients.

Thanks to ImgZipper, I can manage assets quickly, reduce bounce rates, and keep emails looking sharp and snappy.
