Complete Guide: Image Optimization for E-commerce
Learn step by step how to optimize your product photos for online stores. From ideal size to perfect compression without losing quality.
1Why is image optimization crucial?
Product images are the most important factor in online purchasing decisions. 93% of consumers consider images as the decisive element. Poorly optimized images can slow down your site, affect SEO, and reduce conversions.
Practical tips
- Use high resolution images (minimum 1000px)
- Maintain consistency across all products
- White background increases conversions by 20%
2Recommended sizes by platform
Each marketplace has specific requirements. Amazon recommends minimum 1000x1000px, Shopify 2048x2048px for zoom, and WooCommerce suggests 1500x1500px. Using the correct size improves user experience and avoids rejections.
Practical tips
- Amazon: 1000x1000px minimum, 2000x2000px ideal
- Shopify: 2048x2048px for zoom function
- eBay: 1600x1600px recommended
3Image formats: PNG vs JPG
PNG offers better quality and supports transparency, ideal for logos and products with defined edges. JPG is lighter, perfect for photographs with many colors. WebP combines the best of both but not all browsers fully support it.
Practical tips
- PNG for transparent backgrounds
- JPG for large photographs
- Compress without losing visible quality
4SEO file naming
The file name directly influences how Google indexes your images. Instead of IMG_001.jpg, use descriptive names like white-nike-air-max-sneaker.jpg. This improves your ranking in Google Images.
Practical tips
- Use relevant keywords
- Separate words with hyphens
- Include brand and product model
