## How to Upscale an Image in 3 Steps

Increasing image resolution with AI only takes a moment.

1. **Upload your image** - Choose a JPG, PNG or WEBP image up to 16 MB.
2. **Let AI upscale it** - The AI enlarges your image up to 4x and restores sharp edges and fine details.
3. **Download the HD result** - Save the upscaled image as a PNG, up to 4096 px on the long side.

## Upscale Images 4x Instantly

Upload a small or low-resolution image and the AI enlarges it up to four times in seconds. Get a larger, clearer version of your photo without resizing it by hand in an editor.

## Sharper Details, Not Just Bigger Pixels

Traditional resizing makes images blurry. AI super-resolution based on Real-ESRGAN-type models predicts missing detail to restore crisp edges, clean textures and readable text.

## Frequently Asked Questions

### What does the image upscaler do?

It enlarges your image four times with AI, reconstructing edges and textures so the result looks sharper than a simple resize.

### What is the maximum output size?

The output is up to 4096 pixels on the longest side. Larger uploads are scaled to fit before upscaling.

### Can upscaling restore any detail?

AI upscaling reconstructs plausible detail, but it cannot recover information that was never captured. Very small or heavily compressed images improve, but will not look like a professional high-resolution photo.

### Which images benefit most?

Product photos, logos, screenshots, illustrations and older low-resolution photos you want to print or use on large screens.

### Does it keep transparency?

Yes. Transparent PNGs keep their alpha channel after upscaling.

### Is the upscaler free?

Yes. You can upscale images online for free, without creating an account.
