AI Image Enhancer

AI Image Enhancer is a free browser tool that sharpens low-resolution or heavily compressed pictures with the Real-ESRGAN super-resolution model. It can keep the original size or upscale 2× or 4×, and the whole computation runs on your own device: on the GPU through WebGPU when available, otherwise on the CPU.

What it does

Original-size enhancement, or 2× and 4× upscaling
Adjustable enhancement strength
Before/after slider and a 100% view for checking fine detail
Keeps transparency (alpha channel)
Automatic GPU (WebGPU) or CPU processing, with a cancel button
Export as WebP

How to use it

Step 1

Open the tool and upload a PNG, JPG or WebP image, or load the built-in low-resolution example.
Step 2

Pick the output size (original, 2× or 4×), the enhancement strength and the device, then start enhancing.
Step 3

Drag the comparison slider and check faces and text at 100%, then download the result as WebP.

Limits and notes

Input: up to 25 MB, 4 megapixels and 4096 px on the longest side.
Output: up to 16 megapixels and 8192 px per side; scales that would exceed this are disabled.
The first run downloads about 27 MB of model files. CPU mode and large images are noticeably slower.
The AI invents plausible texture. It cannot recover detail lost to strong blur, and it may change faces, small text or patterns.

Privacy

Your image never leaves the browser. The site only serves static files and the AI model; all enhancement happens on your device.

Questions

Can it fix a badly out-of-focus photo?

Only partly. Super-resolution works best on low-resolution and compression damage. Information lost to heavy blur is gone, so the model guesses texture instead. Always inspect the result at 100%.

Do I need a graphics card?

No. With a WebGPU-capable browser such as current Chrome or Edge it uses your GPU; otherwise, or if the GPU run fails, automatic mode switches to the CPU, which is slower but works.
