ImgLab tool

AI Image Upscaler

Enlarge images with browser-based Real-ESRGAN processing and compare the result before downloading.

Use case

Choose the right scale before enhancing an image

Photo enhancement works best when it solves a specific output-size problem instead of simply making every image larger.

Set the required output size first, choose the smallest scale factor that reaches it, and judge the result around faces, hair, product labels and high-contrast edges.

  • Use 2x for modest enlargement and 4x only when it is necessary.
  • Compare before and after at the same display size.
  • Export a practical format for the final destination.

How to get better results with this tool

Best use cases

  • Small photos that need a larger preview.
  • Old product images, screenshots or social assets.
  • Comparing 2x and 4x enlargement before download.

Recommended settings

  • Use Fast for quick drafts and batches.
  • Use Detailed when edge quality matters more than speed.
  • Choose the smallest scale that meets the destination size.

Common sizes and limits

  • Very blurry sources may not recover clean detail.
  • Large outputs can use significant browser memory.
  • JPG is practical for photos; PNG is useful for graphics.

Quality checks

  • Inspect faces, hair, text, edges and fine patterns.
  • Watch for artificial texture.
  • Keep the original source file.

Workflow

  1. Upload the image or batch.
  2. Choose a scale factor and mode.
  3. Compare the original and result.
  4. Download the version that passes review.

FAQ

Does upscaling create real detail?

It estimates plausible detail from the source; it cannot restore information that was never captured.

Should I use 2x or 4x?

Use the smallest scale that meets the need for a more natural result.

Why can an upscaled image look artificial?

Very blurry or heavily compressed sources can produce invented texture. Review important details before using the output.

Should I compress after upscaling?

Usually yes for web publishing, because upscaling increases pixel count and file size.
