How It Works

Your image is loaded and redrawn onto a Canvas at the requested dimensions using high-quality browser scaling.

With aspect ratio locked, only the width is used and the height is calculated automatically so the image is never stretched.

The result is encoded as a JPG at your chosen quality and downloaded immediately.

Larger reductions mean faster page loads, at the cost of some sharpness.

Frequently Asked Questions (FAQ)
