About this tool
Set a max width and/or height and the image is scaled down to fit within them (never scaled up), keeping its aspect ratio — leave either blank to only constrain the other. The quality slider controls JPEG/WebP compression: lower it for a smaller file at the cost of some visible detail, higher for a closer-to-original look at a larger size. PNG stays lossless regardless of the slider, so resizing is the main way to shrink a PNG here.
Nothing is uploaded anywhere — the file never leaves your device. Everything here runs as JavaScript in your browser tab.
