Drop images here to compress to 20 KB
JPG · PNG · WebP · AVIF — up to 20 files, 50.00 MB each. Nothing is uploaded.
What 20 KB is usually for
A 20 KB ceiling shows up wherever a form or a platform decides for you: upload caps on marketplaces, maximum attachment sizes in webmail, profile pictures that must stay small, or a CMS that silently rejects anything larger. Instead of loading the picture into an editor and saving at random quality levels until it fits, you set the ceiling once here and the tool does the guessing.
The search runs quality-first, resolution-second, so 20 KB is reached with the sharpest possible result. If you need a different ceiling, the other sizes are one click away.
Frequently asked questions
How do I compress an image to 20 KB?
Drop your images into the box above. The tool starts at full resolution and the highest quality, then lowers the quality and — only if that is still not enough — the dimensions, until every file lands under 20 KB. The exact output size is shown next to each file before you download it.
Are my images uploaded anywhere?
No. Everything happens in your browser on your own device. There is no upload step and no copy of your file on a server.
What if the image cannot reach 20 KB?
Very large photos occasionally cannot be squeezed that far without becoming unusable. When that happens the result is marked with a note instead of pretending it worked, and the smallest file the tool could produce is offered for download.
Does it cost anything?
No. The tool is free, needs no account, and adds no watermark. Because the processing happens on your device, there is no per-file cost that would justify a paywall or a limit.
