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.
How Nventory Helps
Nventory automatically optimizes product images when you upload them to your catalog. Combined with our built-in CDN, your product photos load instantly on every sales channel — from your own storefront to Amazon, eBay, and beyond.

At quality settings above 80%, compression is virtually invisible to the human eye. The before/after preview lets you judge the tradeoff. Product images typically compress well since they have clean backgrounds.
Yes. The compression process strips all EXIF metadata (camera info, GPS data, etc.) from your images, which is recommended for privacy when uploading to marketplaces.
JPG is the most widely accepted format across all marketplaces. WebP offers better compression at the same quality but isn't accepted by all platforms. PNG is lossless but produces larger files.
