how to

How to resize an image by a percentage

Drop your images in the box above.
Move the Scale slider. It starts at 50%, which halves the width and height.
Click Resize images and save, or download all as a ZIP.

Scaling by percent keeps the exact shape of every image, so a batch of different sizes all shrink by the same amount. 50% makes the file roughly a quarter of the pixels.

FAQ

Resize image by percent: questions

Does 50% make the file half the size?

Usually smaller than that: half the width and half the height is a quarter of the pixels.

Can I make an image bigger?

Yes, up to 400%. Enlarging can't add real detail, so it may look soft.
