Upscale product photos to 4K without fake textures

Marketplaces enable hover-zoom when the image is large enough, and zoom sells materials. But an upscaler can invent texture: knit turns into noise, leather turns into plastic, small print turns into gibberish. The rule is upscale once, at the very end, and compare against the real product.

Name the material in the instruction so the model reinforces the right detail. If there is small print on the product, check it after upscaling — if letters changed, fall back to a lower factor or fix the text with a Qwen text edit afterwards.

You'll need

Finish edits first

Cutout, relight and text edits on the original size. Upscaling is the last step.

Choose the factor

2× for images around 1000 px, 4× for very small sources. Aim for 2000–4000 px on the long side.

Name the material

Full-grain leather, rib knit cotton, brushed aluminium — so detail is restored, not invented.

Compare at 100%

Side-by-side with a close-up of the real item. Check stitching, grain and any printed text.

Export

High-quality JPEG or WebP. Keep the master PNG for future edits.

Paste this instruction

Upscale this product photo 4x. Restore real material detail: full-grain leather texture, visible stitching, brushed metal buckle. Keep colours, shape and any printed text exactly the same. No added noise, no over-sharpening, no plastic look.

Don't stack

Do not upscale, then edit, then upscale again — each pass adds artefacts. Do not sharpen faces or labels until they look etched.
