Increase an image's resolution

Increase an image's resolution 2x or 4x with AI, without it looking pixelated, directly in your browser.

Processed on your device via WebAssembly. Nothing is sent to any server.

or click to select it

Uses a super-resolution model (Real-ESRGAN, compact variant) running in your browser via WebAssembly: it reconstructs plausible detail instead of simply stretching existing pixels, unlike classic resizing.

Use cases

  • Enlarging a small photo to print it bigger.
  • Preparing a low-resolution image for a large screen.
  • Enlarging an icon or logo without losing sharpness.

How it works

  1. 1

    Upload the image

    You'll see its original dimensions.

  2. 2

    Choose 2x or 4x

    4x gives maximum detail; 2x is faster.

  3. 3

    Click "Enhance"

    The first time it downloads an AI model (~5 MB).

Frequently asked questions

How is this different from "Resize Image"?

Resize Image stretches the existing pixels (faster, but can look blurry when enlarging a lot). This tool uses AI to reconstruct plausible detail, giving a better visual result when increasing size.

Why does 4x take longer than 2x?

The model always computes at 4x internally; 2x simply rescales that result down by half, so the computation time is the same either way.
