Resizing without distortion or quality loss

Making an image smaller is safe — the browser samples the original pixels down, keeping the result crisp. Enlarging beyond the original dimensions can't add real detail, so upscaled images look softer as new pixels are interpolated.

Keeping 'Lock aspect ratio' on scales width and height together so nothing is stretched. Common targets: 1920px wide for full-screen web images, 1080×1080 for square social posts, or a specific size an upload form requires. The resized file is generated entirely on your device.

Frequently asked questions

Will resizing reduce image quality?

Making an image smaller keeps it crisp. Enlarging beyond the original size can look soft, since new pixels are interpolated.

Can I keep the aspect ratio?

Yes. With aspect lock enabled, changing one dimension updates the other automatically.

What formats can I resize?

JPG, PNG and WebP. The output keeps the original format unless you convert it afterward.
