How it works

Drop an image to resize.
Enter a target width/height in pixels, or a percentage of the original.
Keep the aspect-ratio lock on to avoid stretching, or turn it off for exact dimensions.
Choose PNG, JPEG, or WebP output and download the resized image.

What people use it for

Fitting an image to an exact pixel size for a website or upload form.
Scaling a photo down by a percentage without doing the math.
Producing a specific dimension like an avatar or header image.

Good to know

Enlarging past the original resolution interpolates pixels. It cannot add real detail that was not captured.
Turning off the aspect-ratio lock lets you set exact dimensions but can distort the image.

Frequently asked questions

Can I resize to exact pixels?

Yes, enter the exact width and height. Keep the lock on to preserve proportions, or turn it off when you need precise dimensions even if it changes the aspect ratio.

Which output format should I pick?

PNG for sharp graphics and transparency, JPEG for photos, WebP for the smallest file at good quality.

Is my image uploaded?

No. Resizing is a local canvas operation in your browser.
