What is image upscaling?
Definition
Image upscaling is making an image larger by adding pixels. Simple methods stretch existing pixels and look soft. AI upscaling predicts detail for the new pixels, so the larger image looks sharper. The added detail is generated, not recovered from the scene.
Why it matters for sellers
Sellers sometimes only have a small image, such as a supplier photo or an old product shot, and a marketplace asks for a larger size. Upscaling can bring such an image closer to the needed size when a reshoot is not possible.
Upscaling has limits. It can sharpen edges and textures, but it can also invent details that were not in the original, such as smoothed fabric or altered text. For a listing, check the result closely so the product still looks like the real item.

Examples
Small supplier photo
A reseller gets a small product image from a supplier. Upscaling gives it more pixels so it can meet a larger listing size.
Old catalog scan
A shop owner scans a printed catalog page and upscales the scan to reuse the product picture online.
Label text check
After upscaling a bottle photo, the seller zooms in and finds the small label text slightly altered, so reshoots that one photo.
Frequently asked questions
Does upscaling restore lost detail?
No. It estimates plausible detail from patterns it has learned. The result can look sharper, but it may differ from the real product.
Is upscaling better than resizing larger?
A plain resize stretches pixels and tends to look soft. AI upscaling usually looks sharper, though it can introduce errors.
When should I reshoot instead?
If the photo is blurry, badly lit or the product details matter, such as printed text or small parts, a new photo is more reliable.
Does upscaling cost credits?
AI tools in Instasize run on credits on paid plans. See the pricing page for the current plans.
