Supplier images often arrive at 800px. Shopify themes look best at 2048px. Real-ESRGAN closes the gap without blur.
Shopify recommends 2048×2048 product images so they stay crisp on retina screens and in theme zoom. Dropshipping and wholesale suppliers rarely provide that — most images are small, compressed JPGs.
Stretching them in an editor just enlarges the blur. An AI upscaler reconstructs edges and texture so a 1000px image becomes a convincing 2000px+ image suited to product pages.
Upload the product image: PNG, JPG or WebP. Transparent PNGs keep their transparency.
Choose 2x or 4K: 2x takes a 1000px image to 2000px; 4K output suits hero banners and collection headers.
Re-upload to Shopify: Replace the product media; Shopify generates the smaller sizes from your large original.
Zoom that holds up: Texture and edges are rebuilt, so shoppers zooming in see detail rather than mush.
Alpha preserved: Cut-out products on transparent backgrounds stay transparent after upscaling.
Batch a catalogue: Upscale an entire collection in one pass.
What image size does Shopify recommend? 2048×2048 pixels for square product images. Shopify accepts up to 4472×4472 and 20MB.
Will upscaling slow my store down? No. Shopify serves resized, compressed versions to each device automatically; the large original is only used for zoom.
Can it fix heavy JPEG compression? It reduces blockiness noticeably. For very compressed images, run the Image Denoiser first, then upscale.
