When to use Resize Image by Percentage

Make an image 50% smaller or 200% larger in one step. Enter a percentage and the new width and height are calculated for you.

The best image settings depend on where the picture will be used. Pixel dimensions describe width and height; file size describes bytes. Changing one does not guarantee a particular value for the other. Keep the original, compare the result at its intended size, and choose a format accepted by the destination.

Frequently Asked Questions

Does 50% mean half the file size?

50% halves width and height, so the image has about a quarter of the pixels and usually a much smaller file.
