Resize an image by percentage
Scale an image by a percentage rather than to a fixed size.
This is the right tool when you do not care about the exact pixel dimensions and only want the picture smaller — halving a set of screenshots, say, or cutting a batch of photographs down for a document.
Fifty percent means half the width and half the height. That is a quarter of the pixels, which usually means a dramatically smaller file.
Percentages compound. Two passes at fifty percent leave you with a quarter of the width, not half, so resize once from the original whenever you can.
Accepts: image/png, image/jpeg, image/webp
