Choose the smallest enlargement that passes your final-size check

HD Upscaler uses Real-ESRGAN to enlarge an existing image. It does not need a text prompt. Start with the cleanest original you have, decide where the result will be used, and compare detail at that viewing size. More pixels do not prove that lettering, a face or a product detail has been recovered correctly.

Creative job Start with Decision rule
Choose between 2×, 4× and 8× Compare scale on the same source A fictional 1,000 × 750-pixel source becomes 2,000 × 1,500 at 2× or 4,000 × 3,000 at 4×. That is dimension arithmetic, not a quality score. Start at the smallest scale that meets the delivery size.
Prepare a print or large display Check the final layout Place the enlarged file in the real design before approval. Inspect important edges and text at the intended print size or display size; a zoomed-in preview alone does not establish that the asset is ready.
Handle damage before enlargement Review restoration first Enlarging a scratch or compressed face can make the defect more obvious. Keep an untouched master and compare a restoration candidate before deciding whether it also needs more pixels.

A controlled workflow that wastes fewer generations

  1. Keep the original file and record its pixel dimensions. This QuestStudio upscaler accepts a single image up to 2,000,000 input pixels. A 1,400 × 1,400 image is 1,960,000 pixels; a 2,000 × 2,000 image is 4,000,000 and must be resized first. Preserve the original when making that smaller working copy.
  2. Choose the scale in the Upscaler Options. Leave face enhancement off for the first comparison. If a portrait needs a second audition, change that setting alone so you can see which result changed the eyes, mouth or skin texture. Do not use face enhancement to certify identity.
  3. Use the same crop to compare the source and candidate at a common display size. Check three areas: fine edges such as hair or stitching, text such as a label, and a smooth area where compression or sharpening halos may appear. A sharper invented character or altered seam is a rejection, not a successful repair.
  4. Inspect the downloaded file in its intended layout. For a product listing, read the actual label and compare the silhouette against the source. Keep the smaller acceptable version when a larger version adds halos, false texture or an impractical file size. Save the source, scale, face setting and selected result together.

Questions before you generate

Do I write a prompt for HD Upscaler?

No. Supply an image, select the scale and review the optional face-enhancement setting. This tool enlarges an existing image; text-to-image generation is a different workflow.

Why is my source image rejected?

QuestStudio checks this upscaler's source before processing. Use a supported single-image file with no more than 2,000,000 pixels. Width multiplied by height gives the input pixel count. Resize a copy if necessary and keep your original.

Is 8× always better than 2×?

No. A larger image can still contain incorrect texture, changed text or sharpening artifacts. Choose the smallest scale that meets your delivery size and passes a comparison against the source.

Can upscaling recover the exact original face or lettering?

Do not assume that generated detail is the lost original. Compare identity, spelling and product geometry with a reliable source. Reject a plausible-looking result when those details have changed.
