Why Compress Product Images?
Large product images slow down your listings and frustrate shoppers. Studies show that a one-second delay in page load time can reduce conversions by up to 7%. Compressing images keeps your pages fast while maintaining the visual quality buyers expect.
Marketplace File Size Limits
- Amazon — Up to 10 MB per image. Recommended under 1 MB for fast listing load times and mobile performance.
- eBay — Maximum 7 MB per image. Listings with optimized images rank higher in search results.
- Shopify — Allows up to 20 MB, but Shopify recommends keeping product images under 500 KB for the fastest storefront performance.
- Etsy — Strict 1 MB limit per image. Compression is essential for high-resolution product photography on Etsy.
How This Tool Works
This compressor runs entirely in your browser — your images are never uploaded to a server. It uses advanced algorithms to reduce file size while preserving visual fidelity. EXIF metadata is automatically stripped to save additional bytes and protect your privacy.
