WebP to PNG: How I Saved Our Email Campaign in 10 Minutes

I spent weeks optimizing our landing page images as WebP. Page load dropped 40%. Lighthouse score hit 95. Then marketing sent the weekly newsletter. Every product image was broken. The Problem Nobody Talks About Email clients do not render WebP. Gmail, Outlook, Mailchimp — none of them support it. All that optimization meant nothing when our customers saw broken image placeholders. The Emergency Fix I batch-converted 200 product photos back to PNG in one go. The tool preserved alpha channels on transparent product shots, which was critical — our previous converter flattened them to white backgrounds. What I Use Now webp2png.io handles batch WebP-to-PNG conversion including transparency. No upload, runs in the browser. My rule: WebP for the web, PNG for everything else. What format headaches have you dealt with?
