Overview

ESRGAN Image Upscaler enhances and upscales a source image using Real-ESRGAN with configurable scale, model variant, tiling, face enhancement, and PNG/JPEG output. Use it when a campaign visual, product image, thumbnail, or social asset needs a larger or cleaner image for review or reuse.

Use cases

  • Upscale a low-resolution campaign image before using it in a deck, landing-page mockup, or social post.
  • Compare Real-ESRGAN model variants for general, anime, or detail-sensitive source images.
  • Use face enhancement for portrait-style assets when facial detail matters.
  • Use tiling when a larger source image needs smaller processing chunks.

Input tips

  • Provide a public image_url that can be fetched without login.
  • Choose scale from 1-8; default is 2.
  • Pick a model variant that matches the source image, such as general or anime-oriented variants.
  • Enable face enhancement only for portraits or people-focused images.
  • Use tile only when a large image needs chunked processing; 0 means no tiling.
  • Choose png for most review outputs or jpeg when file size matters.

Expected output

The AI Tool returns one upscaled image with a downloadable URL, optional content type, file name, file size, width, height, the original image URL for comparison, and cost metadata. The output view shows a before/after comparison slider plus dimensions, file size, format, and Real-ESRGAN model label when available.

Caveats

  • Source image URLs must be public and reachable.
  • Upscaling can sharpen or enlarge an image, but it cannot recover details that were never present.
  • Face enhancement can change appearance; review portraits carefully.
  • Model, scale, tile, and output format settings can affect texture, artifacts, and file size.
  • Text, logos, product details, and rights-sensitive content should be reviewed before use.
