About Resize Image
Resizing changes an image's pixel dimensions — its width and height — which is different from compression (changing file size at the same dimensions). You resize to fit a photo into a layout, meet an upload's maximum dimensions, make a thumbnail, or shrink a huge camera image that's far larger than any screen needs. This tool lets you set an exact width or height and, with aspect ratio locked, calculates the other side automatically so the image never looks stretched.
Downscaling vs upscaling
Making an image smaller is safe and usually improves sharpness for its new size. Making it larger can't invent detail that wasn't captured, so an upscaled image looks soft or blocky — start from the highest-resolution original you have whenever you need something bigger. Resize first, then compress if you also need a smaller file.
