How to Upscale Amazon Product Images for Main & Zoom Slots

Amazon's image guidelines push sellers toward high-resolution packshots — ideally 2000 px or more on the longest side so shoppers can zoom into texture, labels, and materials. Many catalogs start from manufacturer JPEGs, phone snapshots, or legacy 800 px assets that fail zoom tests and look soft next to competitors.

When upscaling beats reshooting

• Supplier assets below Amazon's recommended zoom resolution.
• Seasonal SKU updates where only packaging text changed.
• Variant listings that share the same angle but need larger masters.
• International marketplaces that require the same hero at higher DPI.

Recommended workflow

1. Crop to pure white or compliant background before upscale — Amazon rejects cluttered frames.
2. Use the General model at 4× on Starter or 8× on Pro for sub-500 px sources.
3. Compare label text at 100% zoom in the before/after slider.
4. Export PNG for maximum edge fidelity; convert to JPEG only if file size requires it.

Batch a few SKUs on the free tier to validate quality, then move high-volume catalogs to Starter or Pro for watermark-free 4×–8× output and higher daily limits.
