5 WooCommerce Image Optimization Tips

1
Target 800×800px for product images
WooCommerce displays product images at 300–600px on most themes. 800×800px gives 2x retina quality without excessive file size.
2
Use WebP format
WebP is 30% smaller than JPEG at the same quality. All modern browsers support it. Switch from JPEG to WebP to cut your page size significantly.
3
Compress to under 100KB per image
Product pages with 5–10 images should keep each image under 100KB. This keeps total page weight under 1MB for fast loading.
4
Use consistent aspect ratios
WooCommerce looks best with square product images (1:1). Set all images to the same dimensions before uploading.
5
Batch compress before uploading
Compress all images before uploading to WordPress. Our batch tool handles up to 50 images at once — faster than any WordPress plugin.

FAQ

❓ What is the best image size for WooCommerce?

WooCommerce recommends 800×800 pixels for product images. Compress each image to under 100KB in WebP or JPEG format for fast page loading and better Google rankings.

❓ Does image size affect WooCommerce SEO?

Yes. Page speed is a Google ranking factor. Large uncompressed images slow down your WooCommerce store and hurt both SEO and conversion rates.

❓ Should I use WebP or JPEG for WooCommerce?

WebP is recommended for WooCommerce in 2025. It produces files 25–35% smaller than JPEG at the same quality. All major browsers support WebP.

❓ Is it better to compress before or after uploading to WordPress?

Before. Pre-compressing images gives you full control over quality and file size. WordPress plugins like Smush recompress already-compressed images, which can reduce quality.
