Best Image Format for eCommerce Product Photos in 2026

The best image format for eCommerce product photos depends on where the images are going. For your own Shopify or custom store, AVIF delivers the smallest files and fastest load times. For marketplace uploads to Amazon, Etsy, or eBay, stick with high-quality JPG — those platforms re-compress your images anyway and do not accept AVIF. Here is the full breakdown for each platform.

Shopify: Use AVIF for Your Own Store

Shopify added AVIF support in 2022. When you upload a product image in JPG or PNG format, Shopify's CDN automatically serves AVIF to browsers that support it — meaning Chrome, Firefox, and recent Safari. Older browsers still receive JPG automatically.

This means:

• You do not need to upload AVIF files manually — Shopify handles the conversion.
• But if you upload high-quality JPGs (vs highly compressed ones), the AVIF output quality is better.
• Start with the best possible JPG source — at least 1000x1000 pixels, quality 90+. Shopify's CDN handles downscaling and format conversion from there.

If you are running a custom store (not Shopify), manually converting your product JPGs to AVIF and uploading the AVIF files directly gives you the same result without relying on CDN transformation.

Amazon Product Images: JPG or PNG, No AVIF

Amazon requires product images in JPG (JPEG), PNG, TIFF, or GIF format. AVIF is not accepted. For Amazon specifically:

• Main image: JPG on pure white background (RGB 255,255,255), minimum 1000px on the longest side for zoom capability, recommended 2000–3000px.
• Additional images: JPG or PNG, same resolution requirements.
• File size: Amazon does not publish a maximum file size for uploads, but smaller files upload faster. A 2000x2000 JPG at quality 90 is typically 500 KB–1.5 MB — a good range.

Amazon re-compresses and serves your images through their own CDN regardless of what you upload. Focus on resolution and white background compliance, not format optimization — Amazon handles the rest.

Etsy Product Photos: JPG Works Best

Etsy accepts JPG, PNG, and GIF. AVIF is not supported for uploads. For Etsy product photos:

• Use JPG at quality 85–90 for photographs — good balance of quality and file size.
• Use PNG for designs, flat graphics, or any image needing a transparent or clean background.
• Recommended resolution: at least 2000px on the longest side. Etsy's listing page displays images at various sizes and zoom-capable thumbnails benefit from higher resolution.

Etsy compresses and serves images from their own CDN, similar to Amazon. Your upload quality matters most — upload the best JPG you have, and Etsy handles delivery optimization.

Custom Store or WooCommerce/Magento: AVIF Wins

If you run your own e-commerce site outside a major platform, AVIF is the best format for product images. The direct impact:

• Page speed: Product listing pages often load 20–50 images. Converting from JPG to AVIF cuts the total image payload by 50–70%, which directly improves page load time — especially on mobile.
• Google Shopping: Google evaluates page speed as a quality signal. Faster product pages can improve your Google Shopping visibility.
• Conversion rate: Studies consistently show that faster pages convert better. A 1-second improvement in load time can increase conversions by 7% or more.

For a WooCommerce store, install a plugin like Imagify or ShortPixel to automatically serve AVIF. Or pre-convert your product JPGs to AVIF before uploading — the free converter handles batch conversion with no upload limit.

Practical Image Workflow for eCommerce Sellers

A simple workflow that covers all platforms:

1. Shoot or create your product image at high resolution (2000x2000+).
2. Edit in your preferred tool, export as high-quality JPG (quality 90+) as your master file.
3. Upload the master JPG to Amazon, Etsy, and any marketplace — they handle their own optimization.
4. Convert the master JPG to AVIF for your own website product pages using the free converter.
5. Upload AVIF to your CMS or store — serve AVIF to modern browsers with a JPG fallback for older ones.

This gives you one master file for marketplaces and an optimized AVIF for your own site — the best of both worlds without maintaining multiple copies of every product image.

Frequently Asked Questions

Does Shopify automatically convert my product images to AVIF?

Yes, Shopify's CDN automatically generates and serves AVIF versions of your uploaded product images to browsers that support the format (Chrome, Firefox, recent Safari). You upload a JPG and Shopify handles the rest — no manual AVIF conversion needed for Shopify stores.

Can I upload AVIF images to Amazon?

No. Amazon does not currently accept AVIF uploads. Use JPG or PNG for all Amazon product image uploads. Amazon re-compresses and serves images from their own CDN regardless of the format you upload.

What resolution should product photos be for the best results?

Aim for at least 2000x2000 pixels for product photos. This enables zoom functionality on most platforms and ensures sharp display on high-DPI screens. Higher resolution gives you more flexibility without requiring separate uploads for different display sizes.

Does image format affect product page SEO?

Format itself is not a direct SEO signal, but page speed is — and AVIF images load faster. Google uses Core Web Vitals (including LCP, which is often a product image) as ranking factors. Faster product pages rank better and convert at a higher rate.
