Low-resolutionproduct photos, fixed.
Supplier photos are often small and soft. Here is when upscaling rescues them, and when you need a better file.
Updated 10 November 2026
The pixel floors that catch small photos.
Marketplaces judge product photos in pixels, and low-resolution supplier images are where that bites. A thumbnail-sized file can fail at upload, or get through and then look soft with no zoom. These are the figures each platform’s own help pages give:
| Platform | Smallest accepted | What it recommends |
|---|---|---|
| Amazon | 500 px on the longest side; anything smaller cannot be uploaded | 1,000 px or more, which enables zoom |
| TikTok Shop | Asks for 600 × 600 px | Up to 9 images, JPG or PNG, each under 10 MB |
| Shopify | No minimum given for images | 2,048 × 2,048 px for square photos |
First, try for a bigger file.
Ask the supplier for originals
Request the files from their shoot, not the pictures on their website, which are usually resized and compressed.
Skip screenshots
A screenshot records your screen’s pixels, not the photo’s.
Save JPEGs once
Amazon’s file guide advises the highest quality setting and no repeated JPEG saves while editing, since each save costs detail.
Check the pixel size
Open the file’s properties. The longest side is the number marketplaces check.
When upscaling is the right fix.
Sometimes the small file is all there is. Upscaling rebuilds it at a bigger size so it holds up on a product page. Sizzle Photo includes a 4× upscale in every clean-up, inside Shopify, WooCommerce, Wix, PrestaShop, Shoper and Base.
512 px becomes 2,048 px
The size Shopify suggests for square product photos, from a typical supplier thumbnail.
Background included
The same 2 credits also swap the background for white or transparent.
Whole categories at once
Select a supplier’s entire range and apply once. The price shows first.
Originals kept
The small files stay until you choose to replace them, so a weak result costs nothing but credits.
What upscaling cannot fix.
- Missed focus or motion blur. A soft photo comes back larger, and it may still look soft.
- A product that is tiny in the frame. Amazon flags products shown too small, and cropping in discards most of the pixels.
- Supplier watermarks, logos and text burnt into the image.
- The wrong colour, or a variant other than the one you sell.
- Blocky compression from a file saved again and again. Find a cleaner copy if one exists.
- A cropped product. Parts outside the frame stay missing.
Amazon has its own rule here: its Product image guide tells sellers not to artificially enlarge small images, and blurry or pixelated images are a listed reason for suppression. For Amazon, get the larger original first.
Questions about small, blurry photos.
What resolution should product photos be?
Enough for each platform’s recommendation: 1,000 px on the longest side for zoom on Amazon, 2,048 × 2,048 px for square photos on Shopify.
Can AI upscaling fix a blurry product photo?
It helps small, slightly soft files. It cannot bring back detail lost to missed focus or camera shake.
Why does Amazon reject my product images?
Files under 500 px on the longest side are refused at upload. Blurry or pixelated images can also be suppressed after they go live.
Does 72 dpi matter for online product photos?
Amazon asks for at least 72 dpi, but on screen the pixel dimensions decide how sharp a photo looks.
How much does it cost to upscale product photos with Sizzle?
The 4× upscale is part of the 2 credit clean-up, background removal included. A $9 pack covers 500 photos.
