From 8.2s to 2.1s: Image Compression Changed a Store Conversion Rate

Audited a Shopify store. Homepage: 22MB. Product images: 4MB each. Load time: 8.2 seconds.

The Fix

Lossless compression. Same quality. 4MB to 400KB per image. Load time dropped to 2.1 seconds.

compress2png.com handles lossless PNG compression in the browser. No upload needed.

Run Lighthouse before and after compressing. The score jump alone is worth showing clients.
