How to use it

1

Upload your photo

Drop in a JPG, PNG, or WebP up to 25 MB. Use the best original you have; the cleaner the input, the better the result.

2

Pick 2x or 4x

2x is right for most photos around 600–1000px. Use 4x for very small images. Output is capped at 4000px on the longest side.

3

Compare and download

Drag the slider to compare before and after, check the new size against Amazon's zoom guidance, then download the PNG.

Why image resolution matters on Amazon

Amazon only enables hover-to-zoom on product images that are at least 1000px on the longest side, and recommends 1600px or more (up to around 2000px) for the best zoom experience. Shoppers use zoom to inspect texture, stitching, and finish, so a small image quietly costs you conversions.

This tool uses AI upscaling to enlarge your photo while sharpening edges and reducing blur and compression artefacts, rather than simply stretching pixels. It works well on supplier photos, older shots, and images saved at web size.

Be realistic about what upscaling can do: it makes an image larger and crisper, but it cannot invent real detail that the camera never captured. Fine text, tiny labels, or heavily blurred areas may still look soft. For best results, start from the highest-quality original you have.

Once your image is big enough, run it through the Amazon Image Fixer to square it and put it on a pure white background for your main image.

Frequently asked

Is this product image upscaler free?

Yes. This tool is free to use with no sign-up, with a fair-use limit of a few upscales per hour so it stays fast for everyone.

What size do Amazon product images need to be?

Amazon needs at least 1000px on the longest side for zoom to work, and recommends 1600px or larger (around 2000px is ideal). Images can be up to 10,000px, but bigger than about 2000px rarely adds visible benefit.

Should I choose 2x or 4x?

Choose 2x if your image is already 500–1000px; that usually lands you in Amazon's recommended range. Choose 4x for very small images, such as 300–500px thumbnails. Output is capped at 4000px on the longest side.

Can upscaling add detail that isn't in my photo?

No. AI upscaling sharpens edges and cleans up blur and compression, but it cannot recover detail that was never captured. If your original is very blurry or tiny, reshooting or using a better source will always look better.

Do you store my images?

No. Your image is processed to create the upscaled version and is not stored. Download your result before leaving the page.

Why does my large image get reduced first?

To keep the tool fast, images longer than 1500px are scaled down to 1500px before upscaling. If your image is already over 1500px it probably meets Amazon's zoom requirement, so upscaling may not be needed.
