Say how big the file may be and the quality is found for you. Nothing is sent anywhere unless you ask for it.

Or click to choose them. Several at once is fine, and you can drop more later.
Everything re-runs as you change it
JPEG cannot be transparent, so whatever was see-through gets this colour.
Optional. A picture is shrunk on its own anyway when quality alone cannot reach the target, but capping it here usually looks better than letting the quality drop that far.
More than one image comes back as a single .zip.

An encoder takes a quality and answers with a size, never the other way round. So the page tries a quality, looks at the result and halves what is left to search, about nine times per image. Each row says which quality it settled on.
A large photo pushed towards a small target runs out of quality before it runs out of pixels. Below 30% the search stops lowering quality and starts shrinking the picture instead, which looks better at the same size. A row that still could not get there says so rather than pretending.
