Ecommerce Product Image Guide (Spain Focus)
Best practices for Spanish ecommerce product images: sizes, formats, compression, marketplace readiness and conversion impact.
High‑quality product images drive trust and conversion, but oversized JPEG/PNG assets silently erode performance and SEO. This guide tailors optimization to Spanish & LATAM‑oriented stores.
Target dimensions
| Type | Recommended | Notes |
|---|---|---|
| Main product | 1200–1600px | Enables zoom, good for retina |
| Gallery thumbs | 300–400px | Keep aspect consistent |
| Hero / banner | 1600–2000px | Consider AVIF for extra savings |
Formats
- WebP as baseline (broad support)
- AVIF for large hero/product if ≥10% smaller than WebP
- PNG only for transparency / UI overlays
Compression workflow
- Export high‑quality source (PNG/TIFF).
- Convert & compress locally with FotoLince (WebP q ~78–82).
- Batch rename with semantic slugs (product + attribute).
- Lazy load below‑the‑fold; always include explicit
width/height.
Marketplace specifics
- Amazon / ML: Prefer square 1200×1200; pure white (#FFFFFF) background.
- Shopify: Serve responsive
srcset(theme optimization). - WooCommerce: Regenerate thumbnails after bulk changes.
Checklist
- Descriptive filenames (brand-model-keyword.webp)
- Consistent aspect for variants
- Use modern formats for mobile bandwidth
- Audit top exit pages for image weight
Summary
Optimize once, reuse across marketplaces. A disciplined format + dimension + compression approach compounds into faster pages and higher conversion.
