Ecommerce image optimization, shopify image compressor, amazon image optimizer, product image compressor, thumbnail image compressor, hero image optimizer, blog image optimizer, and portfolio image optimizer all share one idea: an image bandwidth optimizer / lightweight image creator / website speed image compressor that protects rankings.

How it works

  1. 1

    Choose the slot (hero, thumb, SKU)

    Hero image optimizer needs sharper settings; thumbnail image compressor can go smaller. Drop JPG/PNG/WebP into the website image optimizer flow.

  2. 2

    Compress for web performance

    Web image compression and page speed image optimization happen in Wasm so seo image optimization does not require a CMS plugin install.

  3. 3

    Publish lighter assets

    Upload lightweight website images to WordPress, Shopify, or Amazon. Resize/crop first when dimensions dwarf the layout.
