Drop your images and each one comes back at or below 20 KB, at the best quality that fits. 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.
Exam, visa and job application portals often cap photos and signatures at 20 KB and reject the upload outright when a file is a single byte over.
At this size a photo has to be small. Setting the longest edge to about 400 pixels usually looks better than letting the quality drop that far.
The whole picture has to fit into about 20,000 bytes. A smaller picture at good quality looks sharper than a large one at very low quality, so cap the longest edge.
Each result is at or below 20 KB, counted as 1024 bytes per KB the way Windows shows it. A portal that counts 1000 bytes per KB allows slightly less, so enter 19 KB to be safe. Check the pixel size it asks for as well.
No. Every attempt at the target size is encoded by your own browser, so the picture never leaves your device.

Below 30% quality the search stops lowering quality and shrinks the picture instead, which looks better at the same size. A result that still cannot get there says so.
